Don't dereference an existing symlink being replaced.
I.E. generate the symlink relative to the symlink's containing dir,
rather than to some arbitrary place it points to.
* src/ln.c (convert_abs_rel): Don't consider the final component
of the symlink name when canonicalizing, as we want to avoid
dereferencing the final component.
* tests/ln/relative.sh: Add a test case.
* NEWS: Mention the fix.

maint: improve error messages upon failed read, write, access, close2013-02-06T15:57:34ZBenno Schulenbergbensberg@justemail.net2013-01-04T21:45:34Zurn:sha1:a1ee5cd714c0825b0244d09bbaa0a61c883ac18f
Note we use "failed to {access,close}" for those single operations,
and "error {read,writ}ing" for those partial operation failures.
* src/copy.c: Improve error messages for failing read, write and close.
* src/cp.c: Improve error messages for failing access.
* src/dd.c: Improve error messages for failing read, write and open.
* src/head.c: Improve error message for failing close.
* src/install.c: Improve error messages for failing access.
* src/ln.c: Likewise.
* src/mv.c: Likewise.
* src/touch.c: Improve error message for failing close.
* src/truncate.c: Likewise.
maint: define usage note about mandatory args centrally2013-01-23T00:03:38ZBernhard Voelkermail@bernhard-voelker.de2013-01-23T00:03:38Zurn:sha1:4eaadb47430f21aee83eb920378be01945845a9a
Each program with at least one long option which is marked as
'required_argument' and which has also a short option for that
option, should print a note about mandatory arguments.
Define that well-known note centrally and use it rather than
literal printf/fputs, and add it where it was missing.
* src/system.h (emit_mandatory_arg_note): Add new function.
* src/cp.c (usage): Use it rather than literal printf/fputs.
* src/csplit.c, src/cut.c, src/date.c, src/df.c, src/du.c:
* src/expand.c, src/fmt.c, src/fold.c, src/head.c, src/install.c:
* src/kill.c, src/ln.c, src/ls.c, src/mkdir.c, src/mkfifo.c:
* src/mknod.c, src/mv.c, src/nl.c, src/od.c, src/paste.c:
* src/pr.c, src/ptx.c, src/shred.c, src/shuf.c, src/sort.c:
* src/split.c, src/stdbuf.c, src/tac.c, src/tail.c, src/timeout.c:
* src/touch.c, src/truncate.c, src/unexpand.c, src/uniq.c:
Likewise.
* src/base64.c (usage): Add call of the above new function
because at least one long option has a required argument.
* src/basename.c, src/chcon.c, src/date.c, src/env.c:
* src/nice.c, src/runcon.c, src/seq.c, src/stat.c, src/stty.c:
Likewise.
doc: make a --help text fragment identical to three others2013-01-10T20:32:33ZBenno Schulenbergbensberg@justemail.net2013-01-04T21:07:49Zurn:sha1:119d9f7ed7c153a4f5c8c03e072ca0436b03f424
* src/ln.c (usage): Move a newline to the next text fragment, so
the preceding fragment about backup methods becomes the same as
the ones for cp, mv, and install. A bit easier for translators.
maint: update all copyright year number ranges2013-01-01T03:51:20ZJim Meyeringjim@meyering.net2013-01-01T02:54:51Zurn:sha1:77da73c75432f3c5b4beebae7b0797a1e33160bc
Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.
ln: add the --relative option2012-03-22T20:51:20ZHarald Hoyerharald@redhat.com2012-03-22T20:51:20Zurn:sha1:15b8318e93a947d1422e9a927f699eda1085cf0d
With the "--relative --symbolic" options, ln computes the relative
symbolic link for the user.
So, ln works just as cp, but creates relative symbolic links instead
of copying the file.
I miss this feature since the beginning of using ln.

using the relpath module.

Run this (twice):

All affected lines end with \ or \n\, so run this command
until it produces no new changes (4 times):
