Hello Linux users, can someone help writing script for follwing issue. I have one text file(abc.txt) which get updated when some third party program finish running. When external(third party) program doesn't successfully finish, the text file updated with additional line : [munit] Test abc.tests.TestSuite FAILED When external program finish execution successfully then text file doesn't include above line I want to create shell script which check text file(abc.txt) to see if it contains above failure line, if it contains failure line then create another text file(xyz.txt) with just "FAILED" word in it. If text file(abc.txt) doesn't conat above failure line then abc.txt should contain only "PASSED"

This should work fine. I was not sure if on PASSED you wanted it to go to xyz.txt or abc.txt so I assumed xyz.txt as that is where the failed status went to. #!/usr/bin/ksh case $(grep '\[munit\] Test abc.tests.TestSuite FAILED' < abc.txt) in *[a-z]*) print "FAILED" > xyz.txt ;; *) print "PASSED" > xyz.txt ;; esac

Great ...this works as expected. Thanks. Appreciated your time.
