-.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.
