To use the ls command, simply type ls followed by the directory path. For example, to list the contents of the current directory, you can use the command ls without any arguments.
The ls command also supports various options to customize the output. For example, the -l option displays the files and directories in a long format, providing additional information such as permissions, owner, size, and modification date.
2. cd – Change directory
The cd command is used to change the current working directory. It allows users to navigate through the file system and access different directories. By default, the cd command takes you to your home directory.
To change to a specific directory, you can use the cd command followed by the directory path. For example, to change to a directory named “documents” within the current directory, you can use the command cd documents.
The cd command also supports relative and absolute paths. A relative path is specified relative to the current directory, while an absolute path starts from the root directory. For example, to change to a directory named “photos” within the home directory, you can use the command cd ~/photos.
3. pwd – Print working directory
The pwd command is used to print the current working directory. It displays the full path of the directory you are currently in. This can be useful when you need to know the exact location of a file or directory.
To use the pwd command, simply type pwd in the terminal and press Enter. The command will then display the full path of the current directory.
The pwd command is especially helpful when navigating through the file system using relative paths. It allows you to verify your current location and ensure that you are in the desired directory before executing any commands.
4. mkdir – Create a new directory
The mkdir command is used to create a new directory. It allows users to easily create directories to organize their files and directories.
To create a new directory, use the mkdir command followed by the desired directory name. For example, to create a directory named “documents”, you can use the command mkdir documents.
The mkdir command also supports the creation of multiple directories at once. Simply provide multiple directory names separated by spaces. For example, to create directories named “photos”, “videos”, and “music”, you can use the command mkdir photos videos music.
5. rm – Remove files or directories
The rm command is used to remove files or directories. It allows users to delete unwanted files and directories from their system.
To remove a file, use the rm command followed by the file name. For example, to remove a file named “example.txt”, you can use the command rm example.txt.
When removing directories, the rm command requires the -r option to delete the directory and its contents recursively. This ensures that all files and subdirectories within the specified directory are also removed. For example, to remove a directory named “documents” and its contents, you can use the command rm -r documents.
6. cp – Copy files and directories
The cp command is used to copy files and directories. It allows users to duplicate files and directories, either within the same directory or to a different location.
To copy a file, use the cp command followed by the source file and the destination directory or file name. For example, to copy a file named “example.txt” to a directory named “backup”, you can use the command cp example.txt backup/.
When copying directories, the cp command requires the -r option to copy the directory and its contents recursively. This ensures that all files and subdirectories within the specified directory are also copied. For example, to copy a directory named “documents” to a directory named “backup”, you can use the command cp -r documents backup/.
7. mv – Move or rename files and directories
The mv command is used to move or rename files and directories. It allows users to change the location or name of a file or directory.

The grep command also supports various options to customize the search. For example, the -i option performs a case-insensitive search, ignoring the difference between uppercase and lowercase letters. The -r option allows recursive searching in directories and subdirectories.
11. find – Search for files and directories
The find command is used to search for files and directories based on various criteria. It allows users to locate specific files or directories within the file system.
To use the find command, type find followed by the starting directory and the search criteria. For example, to find all files with the extension “.txt” within the current directory and its subdirectories, you can use the command find . -name “*.txt”.
The find command supports a wide range of search criteria, such as file name, size, type, and modification time. It also allows users to perform actions on the found files, such as deleting or executing commands on them.
12. chmod – Change file permissions
The chmod command is used to change the permissions of a file or directory. It allows users to control who can read, write, and execute a file or directory.
To use the chmod command, type chmod followed by the desired permissions and the file or directory name. The permissions can be specified using either symbolic or numeric notation.
In symbolic notation, the permissions are represented by letters: r for read, w for write, and x for execute. For example, to give read and write permissions to the owner of a file named “example.txt”, you can use the command chmod u+rw example.txt.
In numeric notation, the permissions are represented by numbers: 4 for read, 2 for write, and 1 for execute. For example, to give read and write permissions to the owner of a file named “example.txt”, you can use the command chmod 600 example.txt.

To compress a file, use the gzip command followed by the file name. For example, to compress a file named “example.txt”, you can use the command gzip example.txt. This will create a compressed file named “example.txt.gz”.
The gzip command automatically replaces the original file with the compressed version. To keep the original file, you can use the -c option to write the compressed output to the standard output. For example, to compress a file named “example.txt” and keep the original file, you can use the command gzip -c example.txt > example.txt.gz.
16. gunzip – Decompress files
The gunzip command is used to decompress files that have been compressed with gzip. It allows users to restore the original file from a compressed version.
To decompress a file, use the gunzip command followed by the compressed file name. For example, to decompress a file named “example.txt.gz”, you can use the command gunzip example.txt.gz. This will restore the original file named “example.txt”.
The gunzip command automatically replaces the compressed file with the decompressed version. To keep the compressed file, you can use the -c option to write the decompressed output to the standard output. For example, to decompress a file named “example.txt.gz” and keep the compressed file, you can use the command gunzip -c example.txt.gz > example.txt.
