perl 2.0 (no announcement message available)perl-2.0

Some of the enhancements from Perl1 included:

    * New regexp routines derived from Henry Spencer's.
          o Support for /(foo|bar)/.
          o Support for /(foo)*/ and /(foo)+/.
          o \s for whitespace, \S for non-, \d for digit, \D nondigit 
    * Local variables in blocks, subroutines and evals.
    * Recursive subroutine calls are now supported.
    * Array values may now be interpolated into lists: unlink 'foo', 'bar', @trashcan, 'tmp';
    * File globbing.
    * Use of <> in array contexts returns the whole file or glob list.
    * New iterator for normal arrays, foreach, that allows both read and write.
    * Ability to open pipe to a forked off script for secure pipes in setuid scripts.
    * File inclusion via do 'foo.pl';
    * More file tests, including -t to see if, for instance, stdin is a terminal. File tests now behave in a more correct manner. You can do file tests on filehandles as well as filenames. The special filetests -T and -B test a file to see if it's text or binary.
    * An eof can now be used on each file of the <> input for such purposes as resetting the line numbers or appending to each file of an inplace edit.
    * Assignments can now function as lvalues, so you can say things like ($HOST = $host) =~ tr/a-z/A-Z/; ($obj = $src) =~ s/\.c$/.o/;
    * You can now do certain file operations with a variable which holds the name of a filehandle, e.g. open(++$incl,$includefilename); $foo = <$incl>;
    * Warnings are now available (with -w) on use of uninitialized variables and on identifiers that are mentioned only once, and on reference to various undefined things.
    * There is now a wait operator.
    * There is now a sort operator.
    * The manual is now not lying when it says that perl is generally faster than sed. I hope.

+.SH NAME
+gsh \- global shell
+.SH SYNOPSIS
+.B gsh
+[options]
+.I host
+[options] 
+.I command
+.SH DESCRIPTION
+.I gsh
+works just like rsh(1C) except that you may specify a set of hosts to execute
+the command on.
+The host sets are defined in the file /etc/ghosts.
+(An individual host name can be used as a set containing one member.)
+You can give a command like
+
+	gsh sun /etc/mungmotd
+
+to run /etc/mungmotd on all your Suns.
+.P
+You may specify the union of two or more sets by using + as follows:
+
+	gsh 750+mc /etc/mungmotd
+
+which will run mungmotd on all 750's and Masscomps.
+.P
+Commonly used sets should be defined in /etc/ghosts.
+For example, you could add a line that says
+
+	pep=manny+moe+jack
+
+Another way to do that would be to add the word "pep" after each of the host
+entries:
+
+	manny	sun3 pep
+.br
+	moe		sun3 pep
+.br
+	jack		sun3 pep
+
+Hosts and sets of host can also be excluded:
+
+	foo=sun-sun2
+
+Any host so excluded will never be included, even if a subsequent set on the
+line includes it:
+
+	foo=abc+def
+	bar=xyz-abc+foo
+
+comes out to xyz+def.
+
+You can define private host sets by creating .ghosts in your current directory
+with entries just like /etc/ghosts.
+Also, if there is a file .grem, it defines "rem" to be the remaining hosts
+from the last gsh or gcp that didn't succeed everywhere.
+
+Options include all those defined by rsh, as well as
+
+.IP "\-d" 8
+Causes gsh to collect input till end of file, and then distribute that input
+to each invokation of rsh.
+.IP "\-h" 8
+Rather than print out the command followed by the output, merely prepends the
+host name to each line of output.
+.IP "\-s" 8
+Do work silently.
+.PP
+Interrupting with a SIGINT will cause the rsh to the current host to be skipped
+and execution resumed with the next host.
+To stop completely, send a SIGQUIT.
+.SH SEE ALSO
+rsh(1C)
+.SH BUGS
+All the bugs of rsh, since it calls rsh.
+
+Also, will not properly return data from the remote execution that contains
+null characters.
