Top Forums Shell Programming and Scripting How To Run A For Loop In A Remsh? Post 302506178 by methyl on Friday 18th of March 2011 06:12:49 PM

My advice. Protecting Shell special characters in a complex "remsh" line will drive you nuts. It is so important to be aware which Shell special characters will be executed on the local computer and which will be executed on the remote computer. It is not impossible to achieve but please bear in mind the next administrator who reads your code.

The professional approach is to first proliferate the script to each of the remote servers and then invoke the script from a "remsh" command.
This approach means that you can test the script while logged in to the remote server.

RSH(1)							      General Commands Manual							    RSH(1)

NAME
rsh - remote shell SYNOPSIS
rsh [-n] [-l username] host [command] host [-n] [-l username] [command] DESCRIPTION
Rsh connects to the specified host, and executes the specified command. Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does. The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote name must be equivalent (in the sense of rlogin(1)) to the originating account; no provision is made for specifying a password with a com- mand. If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1). Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. Thus the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the localfile localfile, while rsh otherhost cat remotefile ">>" otherremotefile appends remotefile to otherremotefile. OPTIONS
-l username Specify the remote user name. -n Connect standard input of the remote command to /dev/null. Do this if rsh should not inadvertently read from standard input. SEE ALSO
rcp(1), rlogin(1), rhosts(5). BUGS
You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1). 4.2 Berkeley Distribution April 29, 1985 RSH(1)
