Your grep command is, therefore, more safely written as grep -R - "find me" *.php The support in grep for searching recursively is a non-standard extension.įilename globbing patterns that may expand to names starting with a dash should be handled with care to not be confused with command-line options. In short: Process (copy to destination) each name given on the command line according to the given options (recursively). The cp utility would then, for each individually named file or directory, copy that file or directory recursively to the destination directory. The shell would expand the above command to something like cp -r inc/file1 inc/file2 inc/dir1 inc/dir2 /home/myself/mywork/ The cp command works the same way with regards to recursive actions: cp -r inc/* ~/mywork/ This example will only print lines from logfile.txt which contains full word ERROR. You can use the grep -w command in UNIX to find the whole word instead of a just pattern, as shown in the following example. In short: Process (search for matching lines within) each name given on the command line according to the given options (recursively). Example 10: How to search the whole word in a file using the grep command. The first example uses find to locate all. This means you would have found a match in inc.php/subdir/README had that file contained the string find me. Use a combination of the find and grep commands to search for a string that exists in a file in a directory tree. For directories mentioned on the command line, it would search all files and subdirectories beneath the directory for files with contents matching the expression. The grep utility would then search the given files for the expression that you provided. where inc.php happens to be a directory name. ![]() This will be expanded by the shell before the shell executes grep, so the actual command at execution may look something like grep -R "find me" file1.php file2.php inc.php contains a filename globbing pattern, *.php. Your grep command, grep -R "find me" *.php
