grep pattern file
# case nonsensitive research:
grep -i pattern file
# Recursively grep for string <pattern> in folder:
grep -R pattern folder
# Getting pattern from file (one by line):
grep -f pattern_file file
# Find lines NOT containing pattern
grep -v pattern file
# You can grep with regular expressions
grep "^00" file #Match lines starting with 00
grep -E "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" file #Find IP add
# Find all files who contain {pattern} in the directory {directory}.
