- .SH NAME
- gcp \- global file copy
- .SH SYNOPSIS
- .B gcp
- file1 file2
- .br
- .B gcp
- [
- .B \-r
- ] file ... directory
- .SH DESCRIPTION
- .I gcp
- works just like rcp(1C) except that you may specify a set of hosts to copy files
- from or to.
- 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
-
- gcp /etc/motd sun:
-
- to copy your /etc/motd file to /etc/motd on all the Suns.
- If, on the other hand, you say
-
- gcp /a/foo /b/bar sun:/tmp
-
- then your files will be copied to /tmp on all the Suns.
- The general rule is that if you don't specify the destination directory,
- files go to the same directory they are in currently.
- .P
- You may specify the union of two or more sets by using + as follows:
-
- gcp /a/foo /b/bar 750+mc:
-
- which will copy /a/foo to /a/foo on all 750's and Masscomps, and then copy
- /b/bar to /b/bar 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
- .br
- 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.
- .PP
- Interrupting with a SIGINT will cause the rcp to the current host to be skipped
- and execution resumed with the next host.
- To stop completely, send a SIGQUIT.
- .SH SEE ALSO
- rcp(1C)
- .SH BUGS
- All the bugs of rcp, since it calls rcp.
