You can always find the latest version at +.nf + http://www.wg.omron.co.jp/~jfriedl/perl/index.html +.fi + +.SH "QUICK EXAMPLE" +Basic use is simple: +.nf + % search jeff +.fi +will search files in the current directory, and all sub directories, for +files that have "jeff" in them. The lines will be listed with the +containing file's name prepended. +.PP +If you list more than one regex, such as with +.nf + % search jeff Larry Randal+ 'Stoc?k' 'C.*son' +.fi +then a line containing any of the regexes will be listed. +This makes it effectively the same as +.nf + % search 'jeff|Larry|Randal+|Stoc?k|C.*son' +.fi +However, listing them separately is much more efficient (and is easier +to type). +.PP +Note that in the case of these examples, the +.B \-w +(list whole-words only) option would be useful. +.PP +Normally, various kinds of files are automatically removed from consideration. +If it has has a certain ending (such as ".tar", ".Z", ".o", .etc), or if +the beginning of the file looks like a binary, it'll be excluded. +You can control exactly how this works -- see below. One quick way to +override this is to use the +.B \-all +option, which means to consider all the files that would normally be +automatically excluded. +Or, if you're curious, you can use +.B \-why +to have notes about what files are skipped (and why) printed to stderr. + +.SH "BASIC OVERVIEW" +Normally, the search starts in the current directory, considering files in +all subdirectories. + +You can use the +.I ~/.search +file to control ways to automatically exclude files. +If you don't have this file, a default one will kick in, which automatically +add +.nf + -skip .o .Z .gif +.fi +(among others) to exclude those kinds of files (which you probably want to +skip when searching for text, as is normal). +Files that look to be be binary will also be excluded. + +Files ending with "#" and "~" will also be excluded unless the +.B -x~ +option is given. + +You can use +.B -showrc +to show what kinds of files will normally be skipped. +See the section on the startup file +for more info. + +You can use the +.B -all +option to indicate you want to consider all files that would otherwise be +skipped by the startup file. + +Based upon various other flags (see "WHICH FILES TO CONSIDER" below), +more files might be removed from consideration. For example +.nf + -mtime 3 +.fi +will exclude files that aren't at least three days old (change the 3 to -3 +to exclude files that are more than three days old), while +.nf + -skip .* +.fi +would exclude any file beginning with a dot (of course, '.' and '..' are +special and always excluded). + +If you'd like to see what files are being excluded, and why, you can get the +list via the +.B \-why +option. + +If a file makes it past all the checks, it is then "considered". +This usually means it is greped for the regular expressions you gave +on the command line. + +If any of the regexes match a line, the line is printed. +However, if +.B -list +is given, just the filename is printed. Or, if +.B -nice +is given, a somewhat more (human-)readable output is generated. + +If you're searching a huge tree and want to keep informed about how +the search is progressing, +.B -v +will print (to stderr) the current directory being searched. +Using +.B -vv +will also print the current file "every so often", which could be useful +if a directory is huge. Using +.B -vvv +will print the update with every file. + +Below is the full listing of options. + +.SH "OPTIONS TELLING *WHERE* TO SEARCH" +.TP +.BI -dir " DIR" +Start searching at the named directory instead of the current directory. +If multiple +.B -dir +arguments are given, multiple trees will be searched. +.TP +.BI -ddir " DIR" +Like +.B -dir +except it flushes any previous +.B -dir +directories (i.e. "-dir A -dir B -dir C" will search A, B, and C, while +"-dir A -ddir B -dir C" will search only B and C. This might be of use +in the startup file (see that section below). +.TP +.B -xdev +Stay on the same filesystem as the starting directory/directories. +.TP +.B -sort +Sort the items in a directory before processing them. +Normally they are processed in whatever order they happen to be read from +the directory. +.TP +.B -nolinks +Don't follow symbolic links. Normally they're followed. + +.SH "OPTIONS CONTROLLING WHICH FILES TO CONSIDER AND EXCLUDE" +.TP +.BI -mtime " NUM" +Only consider files that were last changed more than +.I NUM +days ago +(less than +.I NUM +days if +.I NUM +has '-' prepended, i.e. "-mtime -2.5" means to consider files that +have been changed in the last two and a half days). +.TP +.B -older FILE +Only consider files that have not changed since +.I FILE +was last changed. +If there is any upper case in the "-older", "or equal" is added to the sense +of the test. Therefore, "search -older ./file regex" will never consider +"./file", while "search -Older ./file regex" will. + +If a file is a symbolic link, the time used is that of the file and not the +link. +.TP +.BI -newer " FILE" +Opposite of +.BR -older . +.TP +.BI -name " GLOB" +Only consider files that match the shell filename pattern +.IR GLOB . +The check is only done on a file's name (use +.B -path +to check the whole path, and use +.B -dname +to check directory names). + +Multiple specifications can be given by separating them with spaces, a'la +.nf + -name '*.c *.h' +.fi +to consider C source and header files. +If +.I GLOB +doesn't contain any special pattern characters, a '*' is prepended. +This last example could have been given as +.nf + -name '.c .h' +.fi +It could also be given as +.nf + -name .c -name .h +.fi +or +.nf + -name '*.c' -name '*.h' +.fi +or +.nf + -name '*.[ch]' +.fi +(among others) +but in this last case, you have to be sure to supply the leading '*'. +.TP +.BI -path " GLOB" +Like +.B -name +except the entire path is checked against the pattern. +.TP +.B -regex " REGEX" +Considers files whose names (not paths) match the given perl regex +exactly. +.TP +.BI -iname " GLOB" +Case-insensitive version of +.BR -name . +.TP +.BI -ipath " GLOB" +Case-insensitive version of +.BR -path . +.TP +.BI -iregex " REGEX" +Case-insensitive version of +.BR -regex . + +.TP +.BI -dpath " GLOB" +Only search down directories whose path matches the given pattern (this +doesn't apply to the initial directory given by +.BI -dir , +of course). +Something like +.nf + -dir /usr/man -dpath /usr/man/man* +.fi +would completely skip +"/usr/man/cat1", "/usr/man/cat2", etc. +.TP +.BI -dskip " GLOB" +Skips directories whose name (not path) matches the given pattern. +Something like +.nf + -dir /usr/man -dskip cat* +.fi +would completely skip any directory in the tree whose name begins with "cat" +(including "/usr/man/cat1", "/usr/man/cat2", etc.). +.TP +.BI -dregex " REGEX" +Like +.BI -dpath , +but the pattern is a full perl regex. Note that this quite different +from +.B -regex +which considers only file names (not paths). This option considers +full directory paths (not just names). It's much more useful this way. +Sorry if it's confusing. +.TP +.BI -dpath " GLOB" +This option exists, but is probably not very useful.

Something like +.nf + -xflag1 -xflag2 +.fi +will turn on "flag1" and "flag2" in the startup file (and is +the same as "-xflag1,flag2"). You can use this to write your own +rules for what kinds of files are to be considered. + +For example, the internal-default startup file contains the line +.nf + <!~> option: -skip '~ #' +.fi +This means that if the +.B -x~ +flag is +.I not +seen, the option +.nf + -skip '~ #' +.fi +should be done. +The effect is that emacs temp and backup files are not normally +considered, but you can included them with the -x~ flag. + +You can write your own rules to customize +.I search +in powerful ways.

However, if this option +is given, the filename is printed and no searching takes place. This turns +.I search +into a 'find' of some sorts. + +In this case, no regular expressions are needed on the command line +(any that are there are silently ignored). + +This is not intended to be a replacement for the 'find' program, +but to aid +you in understanding just what files are getting past the exclusion checks. +If you really want to use it as a sort of replacement for the 'find' program, +you might want to use +.B -all +so that it doesn't waste time checking to see if the file is binary, etc +(unless you really want that, of course). + +If you use +.BR -find , +none of the "GREP-LIKE OPTIONS" (below) matter. + +As a replacement for 'find', +.I search +is probably a bit slower (or in the case of GNU find, a lot slower -- +GNU find is +.I unbelievably +fast). +However, "search -ffind" +might be more useful than 'find' when options such as +.B -skip +are used (at least until 'find' gets such functionality). +.TP +.B -ffind +(or +.BR -ff ) +A faster more 'find'-like find.

These +are described in more detail below. +.RE + +Blank lines and comments (lines beginning with '#') are allowed. + +If a line begins with <...>, then it's a check to see if the +directive on the line should be done or not. The stuff inside the <...> +can contain perl's && (and), || (or), ! (not), and parens for grouping, +along with "flags" that might be indicated by the user with +.BI -x flag +options. + +For example, using "-xfoo" will cause "foo" to be true inside the <...> +blocks. Therefore, a line beginning with "<foo>" would be done only when +"-xfoo" had been specified, while a line beginning with "<!foo>" would be +done only when "-xfoo" is not specified (of course, a line without any <...> +is done in either case). + +A realistic example might be +.nf + <!v> -vv +.fi +This will cause -vv messages to be the default, but allow "-xv" to override. + +There are a few flags that are set automatically: +.RS +.TP +.B TTY +true if the output is to the screen (as opposed to being redirected to a file). +You can force this (as with all the other automatic flags) with -xTTY. +.TP +.B -v +True if -v was specified. If -vv was specified, both +.B -v +and +.B -vv +flags are true (and so on). +.TP +.B -nice +True if -nice was specified. Same thing about -nnice as for -vv. +.PP +.TP +.B -list +true if -list (or -l) was given. +.TP +.B -dir +true if -dir was given. +.RE + +Using this info, you might change the last example to +.nf + + <!v && !-v> option: -vv + +.fi +The added "&& !-v" means "and if the '-v' option not given". +This will allow you to use "-v" alone on the command line, and not +have this directive add the more verbose "-vv" automatically. + +.RS 0 +Some other examples: +.TP +<!-dir && !here> option: -dir ~/ +Effectively make the default directory your home directory (instead of the +current directory). Using -dir or -xhere will undo this. +.TP +<tex> option: -name .tex -dir ~/pub +Create '-xtex' to search only "*.tex" files in your ~/pub directory tree. +Actually, this could be made a bit better. If you combine '-xtex' and '-dir' +on the command line, this directive will add ~/pub to the list, when you +probably want to use the -dir directory only. You could do +.nf + + <tex> option: -name .tex + <tex && !-dir> option: -dir ~/pub +.fi + +to will allow '-xtex' to work as before, but allow a command-line "-dir" +to take precedence with respect to ~/pub. +.TP +<fluff> option: -nnice -sort -i -vvv +Combine a few user-friendly options into one '-xfluff' option. +.TP +<man> option: -ddir /usr/man -v -w +When the '-xman' option is given, search "/usr/man" for whole-words +(of whatever regex or regexes are given on the command line), with -v. +.RE + +The lines in the startup file are executed from top to bottom, so something +like +.nf + + <both> option: -xflag1 -xflag2 + <flag1> option: ...whatever... + <flag2> option: ...whatever... + +.fi +will allow '-xboth' to be the same as '-xflag1 -xflag2' (or '-xflag1,flag2' +for that matter). However, if you put the "<both>" line below the others, +they will not be true when encountered, so the result would be different +(and probably undesired). + +The "magic" directives are used to determine if a file looks to be binary +or not. The form of a magic line is +.nf + magic: \fISIZE\fP : \fIPERLCODE\fP +.fi +where +.I SIZE +is the number of bytes of the file you need to check, and +.I PERLCODE +is the code to do the check. Within +.IR PERLCODE , +the variable $H will hold at least the first +.I SIZE +bytes of the file (unless the file is shorter than that, of course). +It might hold more bytes. The perl should evaluate to true if the file +should be considered a binary. + +An example might be +.nf + magic: 6 : substr($H, 0, 6) eq 'GIF87a' +.fi +to test for a GIF ("-iskip .gif" is better, but this might be useful +if you have images in files without the ".gif" extension). + +Since the startup file is checked from top to bottom, you can be a bit +efficient: +.nf + magic: 6 : ($x6 = substr($H, 0, 6)) eq 'GIF87a' + magic: 6 : $x6 eq 'GIF89a' +.fi +You could also write the same thing as +.nf + magic: 6 : (($x6 = substr($H, 0, 6)) eq 'GIF87a') || ## an old gif, or.. \e + $x6 eq 'GIF89a' ## .. a new one. +.fi +since newlines may be escaped. + +The default internal startup file includes +.nf + magic: 32 : $H =~ m/[\ex00-\ex06\ex10-\ex1a\ex1c-\ex1f\ex80\exff]{2}/ +.fi +which checks for certain non-printable characters, and catches a large +number of binary files, including most system's executables, linkable +objects, compressed, tarred, and otherwise folded, spindled, and mutilated +files. + +Another example might be +.nf + ## an archive library + magic: 17 : substr($H, 0, 17) eq "!<arch>\en__.SYMDEF" +.fi + +.SH "RETURN VALUE" +.I Search +returns zero if lines (or files, if appropriate) were found, +or if no work was requested (such as with +.BR -help ). +Returns 1 if no lines (or files) were found. +Returns 2 on error. + +.SH TODO +Things I'd like to add some day: +.nf + + show surrounding lines (context). + + highlight matched portions of lines. + + add '-and', which can go between regexes to override + the default logical or of the regexes. + + add something like + -below GLOB + which will examine a tree and only consider files that + lie in a directory deeper than one named by the pattern. + + add 'warning' and 'error' directives. + + add 'help' directive. +.fi +.SH BUGS +If -xdev and multiple -dir arguments are given, any file in any of the +target filesystems are allowed. It would be better to allow each filesystem +for each separate tree. + +Multiple -dir args might also cause some confusing effects. Doing +.nf + -dir some/dir -dir other +.fi +will search "some/dir" completely, then search "other" completely. This +is good. However, something like +.nf + -dir some/dir -dir some/dir/more/specific +.fi +will search "some/dir" completely *except for* "some/dir/more/specific", +after which it will return and be searched. Not really a bug, but just sort +of odd. + +File times (for -newer, etc.) of symbolic links are for the file, not the +link. This could cause some misunderstandings. + +Probably more.
