Thank you so much. This is what I was looking for.:)

Unfortunately the error message which i get is:

argv: Subscript out of range

Thank you for your response. I guess this partially work, but I was more looking for an error prompt to the user like:

Hi, Sorry about this but I didn't receive any script from you. Pardon me if I have missed something in your email.

The way it works is:
Example: If the user types:
cluster_on_lev3.csh -dir /home/shared -t 2.3 -p 0.05 -c 26 -l 2"
The above code checks for arguments such as -dir, -t, or -c in the Case statement...

The whole code is:

#!/bin/csh
if (${#argv} < 1) then
USAGE:
echo "USAGE: cluster_on_lev3.csh -dir <full_path Lev3 gfeat cope directory> [options]"
echo "USAGE: cluster_on_lev3.csh...

Thanks, It works now. Infact I had to use sed to insert one more back slash that is replace "\" by "\\" to make it look like set x = 0.314\\0.314.

set x = `command input | sed 's/\\/\\\\/g'`
...

The "double \\" works with floating point numbers which are greater than 1 but doesn't work for numbers between 0 and 1. Try:

set x = 0.314\2.314
echo $x
0.3142.314

I think I have to accept...

linux1% command input

0.48828125\0.48828125
But I want to save this variable using set in c shell and I am doing:
set x = `command input`
echo $x
Incorrect o/p: ...

Yes, You are absolutely correct that this kind of operation doesn't work in bash also.

xxx@linux1% command --i input [option]
o/p
0.48828125\0.48828125
What I tried was:
xxx@linux1% set x =...

Same operation in Bash gives me...

Yes but it didn't work.
when I try single quotes and do echo $x it says:
echo : No match.
The problem is the square brackets because when I remove the square brackets it works just fine.

Hi Guys,
I want to set a variable which happend to have square brackets in them. I tried multiple ways that is by escaping it with quotes (both single and double ) but it didn't help.
All I want...
