+.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.
