I missed the shebang. It works now!

I dont need to make it an environment variable

I have a simple script that sets a value and reads the value in csh:

set -x
set a = 10
echo $a

The output of the script does not show the value of a

0224 098...

p -> print

() helps you group patterns. \(^.\) is represented by \1. Similarly \(.*\) is represented by \2

You cannot use [] instead of ()

sed -n 's/\(^.\)*,\(.*\)/\1"whatever you want to insert here"\2/p' filename.csv

sed -n 's/\(^.\)*,\(.*\)/\1"whatever you want to insert here"\2/p'
