Introduction

Linux command options are a set of parameters that can be used to modify the behavior of a command. They are used to customize the output of a command, or to provide additional information to the command. Command options are usually preceded by a hyphen (-) and are often referred to as flags. They are an essential part of the Linux command line and can be used to make the most of the command line environment.

Examples

1. ls: The ls command is used to list the contents of a directory. It can be used with various options to list files in different formats. For example, the command “ls -l” will list the contents of a directory in a long format, which includes the permissions, owner, group, size, and date of modification for each file.

2. cd: The cd command is used to change the current working directory. For example, the command “cd /home/user” will change the current working directory to the user’s home directory.

3. mv: The mv command is used to move or rename files and directories. For example, the command “mv file1.txt file2.txt” will move the file “file1.txt” to the file “file2.txt”.

4. rm: The rm command is used to remove files and directories. For example, the command “rm -r mydir” will remove the directory “mydir” and all of its contents.

5. chmod: The chmod command is used to change the permissions of a file or directory. For example, the command “chmod 755 myfile” will set the permissions of the file “myfile” to read, write, and execute for the owner, and read and execute for the group and other users.
