.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.
|
||
