Manual searching of a file is possible if the number of files is from 10 to 100, but it is almost impossible to search in millions of files. To solve this problem, UNIX and Linux provide the find command. It is a very useful command for searching files in a computer.

The syntax of using the find command is as follows:

find search_path [option]

Here, in search_path, specify the path in which find should search for file_search_pattern.

A few important options are mentioned in the following table:

Option

Follow symbolic link while searching

-exec cmd ;

Execute command cmd passed as parameter to -exec
