|
- Give the [u]ser who owns a file the right to e[x]ecute it:
|
|
|
|
`chmod u+x {{path/to/file}}`
|
|
|
|
- Give the [u]ser rights to [r]ead and [w]rite to a file/directory:
|
|
|
|
`chmod u+rw {{path/to/file_or_directory}}`
|
|
|
|
- Remove e[x]ecutable rights from the [g]roup:
|
|
|
|
`chmod g-x {{path/to/file}}`
|
|
|
|
- Give [a]ll users rights to [r]ead and e[x]ecute:
|
|
|
|
`chmod a+rx {{path/to/file}}`
|
|
|
|
- Give [o]thers (not in the file owner's group) the same rights as the [g]roup:
|
|
|
|
`chmod o=g {{path/to/file}}`
|
|
|
|
- Remove all rights from [o]thers:
|
|
|
|
`chmod o= {{path/to/file}}`
|
|
|
|
- Change permissions recursively giving [g]roup and [o]thers the ability to [w]rite:
|
|
|
|
`chmod {{[-R|--recursive]}} g+w,o+w {{path/to/directory}}`
|
|
|
|
- Recursively give [a]ll users [r]ead permissions to files. Also give e[X]ecute permissions to files that have at least one execution permission and to all sub-directories:
|
|
|
|
`chmod {{[-R|--recursive]}} a+rX {{path/to/directory}}`
