General Output Control -c, --count Suppress normal output; instead print a count of matching lines for each input file. With the -v, --invert-match option (see below), count non-matching lines. --color[=WHEN], --colour[=WHEN] Surround the matched (non-empty) strings, matching lines...
In this example, grep searches all of the listed files for the string bzip and finds two matches, both in the file dirlist-bin.txt. If we were only interested in the list of files that contained matches rather than the matches themselves, we could specify the -l option: 在这个例子里,g...

Surround the matched (non-empty) strings, matching lines, context lines, file names, line numbers, byte offsets, and separators (for fields and groups of context lines) with escape sequences to display them in color on the terminal. The colors are defined by the environment variable GREP_COL...

This switch will interpret a pattern as an extended regular expression. There’s a ton of different things you can do with this, but here’s an example of what it looks like to use a regular expression with grep. Let’s search a text document for strings that contain two consecutive ‘...
Fzf-like search with regex (or fixed strings with -F), fuzzy matching with up to 4 extra characters with -Z+4 and words only with -w, using -%% for file-wide Boolean searches ug -Q -%% -l -w -Z+4 --sort=best 💡 -l lists the matching files in the TUI, press TAB then ...
But the expression uses two ways to stop at the first closing parenthesis, one is good enough. You can use either of these two: (?<=\()[^)]+ (?<=\().+?(?=\)) In the first one, [^)]+ stands for 'while not )', and in the second one, .+?(?=\)) stands for ...
Checking for strings in multiple files. There will be quite some results in the following query so please scroll to see all of them. We will use the “*” symbol for grep to understand we mean expansion: $ grep "address" /etc/* … grep: /etc/sudoers.d: Is a directory /etc/sudo_...
For example, the command grep -E '{1' searches for the two-character string {1 instead of reporting a syntax error in the regular expression. POSIX.2 allows this behavior as an extension, but portable scripts should avoid it. ENVIRONMENT VARIABLES The behavior of grep is affected by the ...
