There are several commands on Linux systems that allow you to search for files, with find and locate being the most used ones while the grep command is a search utility used primarily to return lines from a file, or files, that match a particular search term.
The grep command searches through the file, looking for matches to the pattern specified. To use it type grep , then the pattern we're searching for and finally the name of the file (or files) we're searching in. The output is the three lines in the file that contain the letters 'not'.
The main difference between grep and find command in UNIX is that the grep is a command that helps to search content and display them according to the user-specified regular expression while the find command helps to search and locate files according to the given criteria.
To include all subdirectories in a search, add the -r operator to the grep command. This command prints the matches for all files in the current directory, subdirectories, and the exact path with the filename. In the example below, we also added the -w operator to show whole words, but the output form is the same.
Grep is a powerful Linux command that lets you search for strings and expressions, across files and directories. It can be used to match patterns in log files, filter out useful information from the output of other commands, and perform recursive searches on nested directories.
By default, grep cannot search directories. If you try doing so, you'll get an error ("Is a directory"). With option -R, searching files within directories and subdirectories becomes possible.
To Show Lines That Exactly Match a Search String The grep command prints entire lines when it finds a match in a file. To print only those lines that completely match the search string, add the -x option. grep -x “phoenix number3” *
To include all subdirectories in a search, add the -r operator to the grep command. This command prints the matches for all files in the current directory, subdirectories, and the exact path with the filename. In the example below, we also added the -w operator to show whole words, but the output form is the same.
Instead of a pipe, use command replacement:
grep user `locate my.cnf`
Try:
locate my.cnf | xargs grep user
