readlink
— display
target of a symbolic link
readlink |
[-fnqsv ] file ... |
The readlink
utility displays the target
of a symbolic link. If a given argument file is not a
symbolic link and the -f
option is not specified,
readlink
will print nothing to standard output about
that file and eventually exit with an error status. If
the -f
option is specified, the output is
canonicalized by following every symlink in every component of the given
path recursively. readlink
will resolve both
absolute and relative paths, and, if possible, return the absolute pathname
corresponding to file. In this case, the argument does
not need to be a symbolic link.
The options are as follows:
-f
-n
-q
readlink
.-s
-q
.-v
readlink
will display errors
about files for which
lstat(2) fails, or without
-f
, which are not symbolic links. This is the
inverse of -q
and -s
.POSIXLY_CORRECT
POSIXLY_CORRECT
is set in the environment, then -v
is the default,
rather than -q
.readlink
will exit with status 1 on a
usage error, or if any of the given file arguments do
not exist, or if -f
is absent and any
file arguments do not name symbolic links. Otherwise
readlink
exits with status 0.
readlink
is expected to conform to
IEEE Std 1003.1-2024 (“POSIX.1”),
provided it is run with POSIXLY_CORRECT
set in its
environment.
The readlink
utility appeared along with
stat
, within which it is integrated, in
NetBSD 1.6.
The stat
utility was written by
Andrew Brown ⟨atatat@NetBSD.org⟩. The
original combined man page was written by Jan
Schaumann ⟨jschauma@NetBSD.org⟩.
