grep in a shell question
Hi Experts,

I am able to run the below command via command line without any issues:

cat test.txt | grep -A 2 "Title"

However, when I put this same command on test.sh and do a ./test.sh, I get the error "grep: illegal option -- A
Usage: grep -hblcnsviw pattern file . . ."

Would appreciate your help.

In the command line, type the below command

Code:
 
which grep

use the output of grep in your shell script ( absolute path of grep )

And no need to use the cat command in your script

Code:
 
grep -A 2 "Title" test.txt

If grep not supports -A and -B options ..
Code:
$ nawk 'c-->0;/Title/{c=2}' infile
