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

`chmod u+x {{file}}`

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

`chmod u+rw {{file_or_directory}}`

- Remove e[x]ecutable rights from the [g]roup:

`chmod g-x {{file}}`

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

`chmod a+rx {{file}}`

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

`chmod o=g {{file}}`

- Remove all rights from [o]thers:

`chmod o= {{file}}`

- Change permissions recursively giving [g]roup and [o]thers the ability to [w]rite:

`chmod -R g+w,o+w {{directory}}`

Refactor: add missing `or_directory` where needed. This commit adds the missing `_or_directory` to any example which is specifying an action affecting a file or a directory, but uses the token `{{path/to/file}}` instead of `{{path/to/file_or_directory}}`. 2019-02-08 00:31:19 +00:00			`chmod u+rw {{file_or_directory}}`
