This tutorial provides an introduction to the find
command in Linux, a versatile utility for searching and locating files and directories based on various criteria.
The find
command is a powerful tool for searching and locating files and directories in a Linux filesystem. It allows users to specify a wide range of criteria to narrow down the search results.
Let's begin by understanding the basic usage of the find
command. The find
command is used to search for files and directories based on specified criteria. And first, by using cd /home/labex/project
, we change to the specified path /home/labex/project
.
Input:
cd /home/labex/project
find "example1.txt"
Output:
example1.txt
In this example, the find
command searches for files with the name example1.txt
within the /home/labex/project
directory.
The find
command provides a plethora of options to customize searches and meet specific requirements.
find [path] [expression]
The default search path is the current directory and the default expression is -print
, and the common find
expression options are:
-name
: Find files by file name.-type
: Find certain type of file.-exec
: find
command executes the shell command given for the matching file.-print
: find
command outputs matching files to standard output using it.The find
command is commonly used to locate files based on their names. In this example, we will search for files named example_name
:
Input:
find /home/labex -name "example_name.txt"
Output:
/home/labex/project/example_name.txt
The find
command can be used to search specifically for directories. In this example, we will find all directories within the /home/labex/project
directory:
Input:
find /home/labex/project -type d
Output:
/home/labex/project
/home/labex/project/documents
The find
command can also be used to execute a command for each matching file. In this example, we will list the permissions and owner of
Input:
find /home/labex/project -name "*.txt" -exec ls -l {} \;
Output:
-rw-rw-r-- 1 labex labex 0 Dec 27 16:37 /home/labex/project/example1.txt
-rw-rw-r-- 1 labex labex 0 Dec 27 16:37 /home/labex/project/example2.txt
-rw-rw-r-- 1 labex labex 0 Dec 27 16:37 /home/labex/project/example_name.txt
The command find /home/labex/project -name "*.txt" -exec ls -l {} \;
searches for files with the extension .txt
in the /home/labex/project
directory and executes the ls -l
command on each found file, displaying their detailed information.
The find
command is a versatile tool for searching and locating files and directories in a Linux system. Its flexibility in specifying search criteria makes it a powerful asset for both basic file searches and complex operations performed by system administrators and advanced users.
