Unter Unix werden sogenannte Links bereits seit vielen Jahren eingesetzt. Sie kennen diese vielleicht schon von anderen Betriebssystemen unter dem Namen „Verknüpfungen“. Um einen Link zu erzeugen, bedient man sich des Kommandos ln. Auch dieses Kommando verfügt über die Option --help, welche Ihnen eine kurze Information zu den verfügbaren Optionen gibt:
bash-2.02$ ln --help
Usage: ln [OPTION]... TARGET [LINK_NAME]
or: ln [OPTION]... TARGET... DIRECTORY
Create a link to the specified TARGET with optional LINK_NAME. If there is
more than one TARGET, the last argument must be a directory; create links
in DIRECTORY to each TARGET. Create hard links by default, symbolic links
with --symbolic. When creating hard links, each TARGET must exist.
-b, --backup make a backup of each existing destination file
-d, -F, --directory hard link directories (super-user only)
-f, --force remove existing destination files
-n, --no-dereference treat destination that is a symlink to a
directory as if it were a normal file
-i, --interactive prompt whether to remove destinations
-s, --symbolic make symbolic links instead of hard links
-S, --suffix=SUFFIX override the usual backup suffix
-v, --verbose print name of each file before linking
-V, --version-control=WORD override the usual version control
--help display this help and exit
--version output version information and exit
The backup suffix is ~, unless set with SIMPLE_BACKUP_SUFFIX. The
version control may be set with VERSION_CONTROL, values are:
t, numbered make numbered backups
nil, existing numbered if numbered backups exist, simple otherwise
never, simple always make simple backups
