Resume Wikipedia de Chgrp

La commande UNIX chgrp permet de changer le groupe d’utilisateur possédant un fichier ou un dossier. Tout comme chown, la commande n’est pas réservée au super-utilisateur : le propriétaire peut aussi effectuer un changement de groupe s’il fait partie du groupe de destination.

NAME

chgrp – change group ownership

SYNOPSIS

chgrp [OPTION]… GROUP FILE…
chgrp [OPTION]… –reference=RFILE FILE…

DESCRIPTION

Change the group of each FILE to GROUP. With –reference, change the
group of each FILE to that of RFILE.

-c, –changes
like verbose but report only when a change is made

-f, –silent, –quiet
suppress most error messages

-v, –verbose
output a diagnostic for every file processed

–dereference
affect the referent of each symbolic link (this is the default),
rather than the symbolic link itself

-h, –no-dereference
affect symbolic links instead of any referenced file (useful
only on systems that can change the ownership of a symlink)

–no-preserve-root
do not treat ‘/’ specially (the default)

–preserve-root
fail to operate recursively on ‘/’

–reference=RFILE
use RFILE’s group rather than specifying a GROUP value

-R, –recursive
operate on files and directories recursively

The following options modify how a hierarchy is traversed when the -R
option is also specified. If more than one is specified, only the
final one takes effect.

-H if a command line argument is a symbolic link to a directory,
traverse it

-L traverse every symbolic link to a directory encountered

-P do not traverse any symbolic links (default)

–help display this help and exit

–version
output version information and exit

EXAMPLES
chgrp staff /u
Change the group of /u to “staff”.

chgrp -hR staff /u
Change the group of /u and subfiles to “staff”.
