| 4 | gcp \- global file copy |
| 5 | .SH SYNOPSIS |
| 6 | .B gcp |
| 7 | file1 file2 |
| 8 | .br |
| 9 | .B gcp |
| 10 | [ |
| 11 | .B \-r |
| 12 | ] file ... directory |
| 13 | .SH DESCRIPTION |
| 14 | .I gcp |
| 15 | works just like rcp(1C) except that you may specify a set of hosts to copy files |
| 16 | from or to. |
| 17 | The host sets are defined in the file /etc/ghosts. |
| 18 | (An individual host name can be used as a set containing one member.) |
| 19 | You can give a command like |
| 20 | |
| 21 | gcp /etc/motd sun: |
| 22 | |
| 23 | to copy your /etc/motd file to /etc/motd on all the Suns. |
| 24 | If, on the other hand, you say |
| 25 | |
| 26 | gcp /a/foo /b/bar sun:/tmp |
| 27 | |
| 28 | then your files will be copied to /tmp on all the Suns. |
| 29 | The general rule is that if you don't specify the destination directory, |
| 30 | files go to the same directory they are in currently. |
| 31 | .P |
| 32 | You may specify the union of two or more sets by using + as follows: |
| 33 | |
| 34 | gcp /a/foo /b/bar 750+mc: |
| 35 | |
| 36 | which will copy /a/foo to /a/foo on all 750's and Masscomps, and then copy |
| 37 | /b/bar to /b/bar on all 750's and Masscomps. |
| 38 | .P |
| 39 | Commonly used sets should be defined in /etc/ghosts. |
| 40 | For example, you could add a line that says |
| 41 | |
| 42 | pep=manny+moe+jack |
| 43 | |
| 44 | Another way to do that would be to add the word "pep" after each of the host |
| 45 | entries: |
| 46 | |
| 47 | manny sun3 pep |
| 48 | .br |
| 49 | moe sun3 pep |
| 50 | .br |
| 51 | jack sun3 pep |
| 52 | |
| 53 | Hosts and sets of host can also be excluded: |
| 54 | |
| 55 | foo=sun-sun2 |
| 56 | |
| 57 | Any host so excluded will never be included, even if a subsequent set on the |
| 58 | line includes it: |
| 59 | |
| 60 | foo=abc+def |
| 61 | .br |
| 62 | bar=xyz-abc+foo |
| 63 | |
| 64 | comes out to xyz+def. |
| 65 | |
| 66 | You can define private host sets by creating .ghosts in your current directory |
| 67 | with entries just like /etc/ghosts. |
| 68 | Also, if there is a file .grem, it defines "rem" to be the remaining hosts |
| 69 | from the last gsh or gcp that didn't succeed everywhere. |
| 70 | .PP |
| 71 | Interrupting with a SIGINT will cause the rcp to the current host to be skipped |
| 72 | and execution resumed with the next host. |
| 73 | To stop completely, send a SIGQUIT. |

| 76 | .SH BUGS |
| 77 | All the bugs of rcp, since it calls rcp. |
