Matching Control -e PATTERN, -regexp= PATTERN Use PATTERN as the pattern. This is highly experimental and grep -P may warn of unimplemented features. P, -perl-regexp Interpret PATTERN as a Perl regular expression. G, -basic-regexp Interpret PATTERN as a basic regular expression (BRE, see below). F, -fixed-strings Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched. Matcher Selection -E, -extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). This version number should be included in all bug reports (see below).
V, -version Print the version number of grep to the standard output stream. Print a usage message briefly summarizing these command-line options and the bug-reporting address, then exit. Direct invocation as either egrep or fgrep is deprecated, but is provided to allow historical applications that rely on them to In addition, two variant programs egrep and fgrep are available.
By default, grep prints the matching lines. We will run the following command >grep ssh config.Grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus ( -) is given as file name)įor lines containing a match to the given PATTERN. # list of available options, their meanings and defaults, please see the # Site-wide defaults for some commonly used options. # configuration file, and defaults at the end. # Thus, host-specific definitions should be at the beginning of the
# Any configuration value is only changed the first time it is set. # Configuration data is parsed as follows: # users, and the values can be changed in per-user configuration files # This is the ssh client system-wide configuration file. config.txt content is like below which is and ssh_config file from an Ubuntu box. In this example grep term is ssh and the file we want to look is named config.txt. We can grep specified word or text just by providing the grep term and the file we want to grep. > grep -help Print Grep Help Information Grep Specified Word or Text We can print help information with the -help option like below. But we may need some helpful information about the usage and options. Grep command in Windows is very similar to the Linux version. We can see that grep command expects some option and file in order to work. So we will provide the Admin privileges by click Yes to the dialog box. This may require some Administrative privileges.
