Examples

Basic usage with changes

chmod ${changes}

Display help message

chmod --help

Give the [u]ser who owns a file the right to e[x]ecute it.

chmod u+x PATH

Give the [u]ser rights to [r]ead and [w]rite to a file/directory.

chmod u+rw PATH

Remove e[x]ecutable rights from the [g]roup.

chmod g-x PATH

Give [a]ll users rights to [r]ead and e[x]ecute.

chmod a+rx PATH

Give [o]thers (not in the file owner's group) the same rights as the [g]roup.

chmod o=g PATH

Remove all rights from [o]thers.

chmod o= PATH

Change permissions recursively, allowing [g]roup and [o]thers to [w]rite.

chmod -R g+w,o+w PATH

Set access rights using numeric (octal) form.

chmod 750 PATH

Add the execute permission bit to directories only. This works because the 'X' is uppercase, meaning only directories will be executable. However, if an existing file is executable, this bit will not be removed.

chmod a+X PATH

Convert string representation of the access right into numeric form and back.
