Question : bash return only first line that contains match
Answered by : charlesalexandre-roy
# Basic syntax:
grep -m 1 "pattern" input_file.txt
# Where -m is the maximum number of matching lines to return, i.e. stop
# reading the file after m matches
# Note, this is more efficient than piping to head because there you
# always read the whole file even if you're only looking for m matchesSource : https://stackoverflow.com/questions/50263627/how-to-extract-only-first-line-that-matches-each-pattern-from-a-file | Last Update : Mon, 03 May 21
