The grep command displays lines that match a specific pattern and is useful in extracting information, but the find command, in addition to locating files, allows you to perform actions on files, such as deleting files, changing permissions, and executing commands. Using grep, the content of the file is searched to find text patterns, while the find command is executed to locate files and directories based on various criteria in the directory hierarchy. Therefore, the purpose of using grep is different from find. Using the grep command, the files are checked and the line that matches your defined pattern is printed. The function of the grep command, which should have been revealed to you by this article, is used to search for complex and regular patterns in the content of files. The Find command checks the directory hierarchy based on the specified criteria and recursively searches for files and directories.

The fgrep command interprets all characters such as $, *, [, |, (,) that have a special meaning for the shell. The fgrep command allows you to search multiple files in the File parameter and find the file that contains the line matching the constant string algorithm you want. fgrep is different from grep, fgrep stands for Fast Global Regular Expression Print, as the name suggests, it is a fast algorithm to search for a text pattern with fixed characters in the file, using which you can search for a pattern that matches fixed strings, while grep helps you search for complex expressions. Some users use fgrep instead of grep and some don’t know the difference between these two commands.
