POSIX requires that options that follow file names must be treated as file names; by default, such options are permuted to the front of the operand list and are treated as options. Also, POSIX requires that unrecognized options be diagnosed as “illegal”, but since they are not really ...
The file is sought in the colon-separated list of directory pathnames specified in the PATH environment variable. 这个文件将在PATH中指定的以冒号分隔的目录路径列表中查找。 If this variable isn't defined, the path list defaults to the current directory followed by the list of directories returned ...
If an input file is a directory, use ACTION to process it. By default, ACTION is read, which means that directories are read just as if they were ordinary files. If ACTION isskip, directories are silently skipped. If ACTION isrecurse, grep reads all files under each directory, recursively...
In the above example, thegrepcommand searches for a pattern in all directories exceptdir1,dir2, anddir3. There’s an alternate syntax to achieve the same results. We canprovide a list of directories incurly braces: $ grep -R"sample"--exclude-dir={dir1,dir2,dir3} logs/service.log:Thi...

-F, --fixed-strings Interpret each pattern as a list of fixed strings, separated by newlines, instead of as a regular SunOS 5.11 Last change: 5 User Commands PCREGREP(1) expression. The -w (match as a word) and -x (match whole line) options can be used with -F. They apply to ...
If you would like to search for a string in the current directory along with all of the subdirectories, you can specify the–roption to search recursively: # grep -r “function” * 9. Search for the Entire Pattern Passing the-woption to grep searches for the entire pattern that is in...
fgrep is the equivalent of grep -F This switch will interpret a pattern as a list of fixed strings, and try to match any of them. It’s useful when you need to search for regular expression characters. This means you don’t have to escape special characters like you would with regular...
List Names of Matching Files To retrieve the names of the files that contain a word or string of characters and exclude the actual lines, use the-loperator: grep -l 'server' * The output shows the filenames that containserverbut does not print the corresponding lines. ...
Note that the complement of --exclude is not --include, because exclusions always take precedence over inclusions, so we cannot reliably list the files that are ignored with --include-from='.gitignore'. Only files explicitly specified with --include and directories explicitly specified with --...
