grep

all

Find patterns in files using `regex`es. See also: `regex`.

Options (6)

-F, --fixed-stringsboolean

Search for an exact string (disables `regex`es)

Example: grep {{[-F|--fixed-strings]}} "{{exact_string}}" {{path/to/file}}

boolean

Search for a pattern in all files recursively in a directory, ignoring binary files

Example: grep {{[-rI|--recursive --binary-files=without-match]}} "{{search_pattern}}" {{path/to/directory}}

boolean

Print file name and line number for each match with color output

Example: grep {{[-Hn|--with-filename --line-number]}} --color=always "{{search_pattern}}" {{path/to/file}}

-o, --only-matchingboolean

Print only the matched text

Example: grep {{[-o|--only-matching]}} "{{search_pattern}}" {{path/to/file}}

-v, --invert-matchboolean

Read data from `stdin` and do not print lines that match a pattern

Example: cat {{path/to/file}} | grep {{[-v|--invert-match]}} "{{search_pattern}}"

boolean

Use extended `regex`es (supports `?`, `+`, `{}`, `()`, and `|`), in case-insensitive mode

Example: grep {{[-Ei|--extended-regexp --ignore-case]}} "{{search_pattern}}" {{path/to/file}}

Search for a pattern within files

grep "search_pattern" path/to/file1 path/to/file2 ...

Search for an exact string (disables `regex`es)

grep [-F|--fixed-strings] "exact_string" path/to/file

Search for a pattern in all files recursively in a directory, ignoring binary files

grep [-rI|--recursive --binary-files=without-match] "search_pattern" path/to/directory

Print 3 lines of [C]ontext around, [B]efore, or [A]fter each match

grep --context|--before-context|--after-context 3 "search_pattern" path/to/file

Print file name and line number for each match with color output

grep [-Hn|--with-filename --line-number] --color=always "search_pattern" path/to/file

Print only the matched text

grep [-o|--only-matching] "search_pattern" path/to/file

Read data from `stdin` and do not print lines that match a pattern

cat path/to/file | grep [-v|--invert-match] "search_pattern"

Use extended `regex`es (supports `?`, `+`, `{}`, `()`, and `|`), in case-insensitive mode

grep [-Ei|--extended-regexp --ignore-case] "search_pattern" path/to/file
