[ILUG] A little grep mystery

[Aidan Kehoe]

 Ar an 4u la de mi 6, scriobh Brian Foster :

 >      #!/bin/bash                 #/bin/bash
 >      export COLUMNS=1000         exec ps.real -w "$@"
 >      exec ps.real "$@"

As I understand it, the left-hand one of those won't work, because GNU
ps _ignores_ terminal settings (of which COLUMNS) is part when writing
to a pipe. Of course, my local GNU ps doesn't do any of this at all; 

$ ps --version
procps version 2.0.6
$ ps -ef | grep Maildir
