The grep command searches one or more input files for lines containing a match to a specified pattern.
How can I list just the names of matching files?
grep -l 'main' *.c
How do I search directories recursively?
grep -r 'hello' /home/gigi
Suppose I want to search for a whole word, not a part of a word?
grep -w 'hello' *
How do I output context around the matching lines?
grep -C 2 'hello' *
How can I search in both standard input and in files?
Use the special file name `-':
cat /etc/passwd | grep 'alain' - /etc/motd
