`egrep "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
|
|
|
|
|
|
- Search for a pattern within multiple files:
|
|
|

|
|
|
- Print file name and line number for each match:
|
|
|
|
|
|
|
|
|

`egrep --with-filename --line-number "{{search_pattern}}" {{path/to/file}}`
|
|
|
|
|
|
|
|
|
|
- Search for a pattern in all files recursively in a directory, ignoring binary files:
|
|
|
|
|
|
|
|
|
|
`egrep --recursive --binary-files={{without-match}} "{{search_pattern}}" {{path/to/directory}}`
|
|
|
|
|
|
|
|
|
|
- Search for lines that do not match a pattern:
|
|
|
|
|
|
|
|
|
|
`egrep --invert-match "{{search_pattern}}" {{path/to/file}}`
|
