Unix Tip #4647- December 1, 2023

PIPES AND QUOTING


When you do rsh (remsh in HP-UX) followed by a series of
pipes, consider carefully whether you want the pipe processes
to run on the local or the remote host. If you quote the
pipes, then they become part of the arguments passed to
the remote host and evaluated there. E.g.

rsh myRemoteHost last "|" grep userName "|" head

(In this example, we pipe the output of last to grep,
because in Solaris "last userName" only shows console
logins, not FTP logins.)
