# fgrep
|
|
|
|
> Matches patterns in files.
|
|
> Supports simple patterns and regular expressions.
|
|
|
|
- Search for an exact string in a file:
|
|
|
|
`fgrep {{search_string}} {{path/to/file}}`
|
|
|
|
- Search only lines that match entirely in files:
|
|
|
|
`fgrep -x {{path/to/file1}} {{path/to/file2}}`
|
|
|
|
- Count the number of lines that match the given string in a file:
|
|
|
|
`fgrep -c {{search_string}} {{path/to/file}}`
|
|
|
|
- Show the line number in the file along with the line matched:
|
|
|
|
`fgrep -n {{search_string}} {{path/to/file}}`
|
|
|
|
- Display all lines except those that contain the given regular expression:
|
|
|
|
`fgrep -v {{^regex$}} {{path/to/file}}`
|
|
|
|
- Display filenames whose content matches the regular expression at least once:
|
|
|
|
`fgrep -l {{^regex$}} {{path/to/file1}} {{path/to/file2}}`
|
