The command to change the permissions of a file in Linux is chmod. You can use this command to set the user, group, and other permissions for a file or directory.

To set the permissions of a file, you must specify the user, group, and other permissions as an octal number. The octal number is a combination of the user, group, and other permissions, which each use three digits.

For example, to give the user read and write permissions, the group read permissions, and the other no permissions, you would use the octal number 644. To give all users read, write and execute permissions, you would use the octal number 755.

Once you know the octal number for the desired permissions, you can use the chmod command to set the permissions of a file. The syntax is as follows:

chmod octal_number filename

For example, to set the permissions of a file called test.txt to 644, you would use the following command:

chmod 644 test.txt
