Author: asomers Date: Thu Jun 8 19:09:55 2017 New Revision: 319714 URL: https://svnweb.freebsd.org/changeset/base/319714 Log: Add tests for ln(1) * Verify that when creating a hard link to a symbolic link, '-L' option creates a hard link to the target of the symbolic link * Verify that when creating a hard link to a symbolic link, '-P' option creates a hard link to the symbolic link itself * Verify that if the target file already exists, '-f' option unlinks it so that link may occur * Verify that if the target file or directory is a symbolic link, '-shf' option prevents following the link * Verify that if the target file or directory is a symbolic link, '-snf' option prevents following the link * Verify that '-s' option creates a symbolic link * Verify that '-w' option produces a warning if the source of a symbolic link does not currently exist Submitted by: shivansh Reviewed by: asomers, ngie MFC after: 1 month Sponsored by: Google, Inc (GSoC 2017) Differential Revision: https://reviews.freebsd.org/D11084 Added: head/bin/ln/tests/ head/bin/ln/tests/Makefile (contents, props changed) head/bin/ln/tests/ln_test.sh (contents, props changed) Modified: head/bin/ln/Makefile head/etc/mtree/BSD.tests.dist Modified: head/bin/ln/Makefile ============================================================================== --- head/bin/ln/Makefile Thu Jun 8 18:20:32 2017 (r319713) +++ head/bin/ln/Makefile Thu Jun 8 19:09:55 2017 (r319714) @@ -1,11 +1,17 @@ # @(#)Makefile 8.2 (Berkeley) 5/31/93 # $FreeBSD$ +.include <src.opts.mk> + PACKAGE=runtime PROG= ln MAN= ln.1 symlink.7 LINKS= ${BINDIR}/ln ${BINDIR}/link MLINKS= ln.1 link.1 + +.if ${MK_TESTS} != "no" +SUBDIR+= tests +.endif .include <bsd.prog.mk> Added: head/bin/ln/tests/Makefile ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/bin/ln/tests/Makefile Thu Jun 8 19:09:55 2017 (r319714) @@ -0,0 +1,5 @@ +# $FreeBSD$ + +ATF_TESTS_SH+= ln_test + +.include <bsd.test.mk> Added: head/bin/ln/tests/ln_test.sh ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/bin/ln/tests/ln_test.sh Thu Jun 8 19:09:55 2017 (r319714) @@ -0,0 +1,217 @@ +# +# Copyright 2017 Shivansh Rai +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# 1.
