why the set rr='echo string|cut not working
I am new to the c shell script, can you let me know why the set rr= is not working.

C shell script
Code:
#! /bin/csh
 
Set tt= 12345_UMR_BH452_3_2.txt
set rr='echo $tt | cut –d”_”  -f1'
syntax error

Remove the space

Code:
set ff=$rr$rr1

Or if you want the space use double quotes.

Code:
set ff="$rr $rr1"
