Top Forums Shell Programming and Scripting Help me add Error Handling to my script Post 302681851 by Don Cragun on Saturday 4th of August 2012 03:46:05 PM

Of the rcp(1) man pages listed on this site, only the Solaris man page specifies exit codes. That man page also has the following warning:
Quote:
When rcp is used to perform third-party copies where either of the
remote machines is not running Solaris, the exit code cannot be relied
upon. That is, errors could occur when success is reflected in the exit
code, or the copy could be completely successful even though an error
is reflected in the exit code.
Your function looks OK, but it can't work if the command it follows doesn't reliably set its exit status.

NAME
rcp -- remote file copy SYNOPSIS
rcp [-px] [-k realm] file1 file2 rcp [-px] [-r] [-k realm] file ... directory DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rname@rhost:path'', or a local file name (containing no `:' characters, or a `/' before any `:'s). -r If any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a direc- tory. -p The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignor- ing the umask. By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file mod- ified by the umask(2) on the destination host is used. -k The -k option requests rcp to obtain tickets for the remote host in realm realm instead of the remote host's realm as determined by krb_realmofhost(3). -x The -x option turns on DES encryption for all data passed by rcp. This may impact response time and CPU utilization, but provides increased security. If path is not a full path name, it is interpreted relative to the login directory of the specified user ruser on rhost, or your current user name if no other remote user name is specified. A path on a remote host may be quoted (using , ", or ') so that the metacharacters are interpreted remotely. Rcp does not prompt for passwords; it performs remote execution via rsh(1), and requires the same authorization. Rcp handles third party copies, where neither source nor target files are on the current machine. SEE ALSO
cp(1), ftp(1), rsh(1), rlogin(1) HISTORY
The rcp command appeared in 4.2BSD. The version of rcp described here has been reimplemented with Kerberos in 4.3BSD-Reno. BUGS
Doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal. Is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host. The destination user and hostname may have to be specified as ``rhost.rname'' when the destination machine is running the 4.2BSD version of rcp.
