NAME
link, unlink — execute link() and unlink() system calls without error checking
SYNOPSIS
/usr/sbin/link
file1
file2
/usr/sbin/unlink
file
DESCRIPTION
The
link
and
unlink
commands perform their respective system calls
(link()
or
unlink())
on their arguments,
abandoning most error checking.
These commands can be executed only by users
who have appropriate privileges.
EXTERNAL INFLUENCES
Environment Variables
LC_MESSAGES
determines the language in which messages are displayed.
If
LC_MESSAGES
is not specified in the environment or is set to
the empty string, the value of
LANG
is used as a default for each
unspecified or empty variable.
If
LANG
is not specified or is set to the empty string, a default of "C" (see
lang(5))
is used instead of
LANG.
If any internationalization variable contains an invalid setting,
link
behaves as if all internationalization variables are set to "C".
See
environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
RETURN VALUE
link
and
unlink
return the following values:
- 0
Operation successful.
- 1
Input syntax error.
- 2
The
link()
or
unlink()
call failed.
WARNINGS
If a directory that contains files other than
.
and
..
is unlinked, the files become orphans,
unless they are also linked by some other directory.
Not all file systems permit linking to directories.
