The theme throughout that was to find out what Shell you were running which could explain the anomolous behaviour and to actually see the script you were running, how you ran it, and any output messages.

We are unwilling to embark on another guessing game. I don't even think we managed to find out what Operating System you had - only that you were using "tcsh".
Methyl,
I apologise and I see where you are coming from. I understand and all I can say is that I am sorry that my knowledge when it comes to unix is not the same as yours, I apologise for ever thinking I could further it by asking questions, I apologise for having the nerve to come onto this forum in the first place, I apologise for not having told you clearly enough in post 9 on that thread that I was using Solaris, but most of all, I apologise for having found out the problem and found the solution, and then having the bloody nerve to ask why it works like that.
I hope with time you can forgive me, and that one day you will realise the world is also full of people who are not as brilliant as you. Next time please try not to put someone down, as thats how I feel. I have just got off the phone from my mother, adn she would like ot apologise for ever giving birth to me.
Regards

NAME
shell-quote - quote arguments for safe use, unmodified in a shell command SYNOPSIS
shell-quote [switch]... arg... DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands or files with embedded white space or shell globbing characters safely. Here are a few examples. EXAMPLES
ssh preserving args When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and passes them to "$SHELL -c". This doesn't work as intended: ssh host touch 'hi there' # fails It creates 2 files, hi and there. Instead, do this: cmd=`shell-quote touch 'hi there'` ssh host "$cmd" This gives you just 1 file, hi there. process find output It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote: eval set -- `find -type f -print0 | xargs -0 shell-quote --` debug shell scripts shell-quote is better than echo for debugging shell scripts. debug() { [ -z "$debug" ] || shell-quote "debug:" "$@" } With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can. save a command for later shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are things the user can't pass through), you can do something like this: user_switches= while [ $# != 0 ] do case x$1 in x--pass-through) [ $# -gt 1 ] || die "need an argument for $1" user_switches="$user_switches "`shell-quote -- "$2"` shift;; # process other switches esac shift done # later eval "shell-quote some-command $user_switches my args" OPTIONS
--debug Turn debugging on. --help Show the usage message and die. --version Show the version number and exit. AVAILABILITY
