- .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.
