grep
Matches patterns in input text. Supports simple patterns and regular expressions.
- Search for an exact string:
grep {{something}} {{file_path}}
- Search in case-insensitive mode:
grep -i {{something}} {{path/to/file}}
- Search recursively in current directory for an exact string:
grep -r {{something}} .
- Use a regular expression (
-E
for extended regex, supporting?
,+
,{}
,()
and|
):
grep -e {{^regex$}} {{path/to/file}}
- Print 3 lines of context around each match:
grep -C 3 {{something}} {{path/to/file}}
- Print the count of matches instead of the matching text:
grep -c {{something}} {{path/to/file}}
- Print line number for each match:
grep -n {{something}} {{path/to/file}}
- Use the standard input instead of a file:
cat {{path/to/file}} | grep {{something}}
- Invert match for excluding specific strings:
grep -v {{something}}
