Even though POSIX.1 lists -a/-o as options to "test", they are marked "Obsolescent XSI". Scripts using these expressions should be converted as follow:
test "$1" -a "$2" should be written as: test "$1" && test "$2" Likewise test "$1" -o "$2" should be written as: test "$1" test "$2" But note that, in test, -a has higher precedence than -o while "&&" and "||" have equal precedence in the shell. The reason for this is that the precedence rules were never well specified, and this made many sane-looking uses of "test -a/-o" problematic. For example, if $x is "=", these work according to POSIX (it's not portable, but in practice it's okay): $ test -z "$x" $ test -z "$x" && test a = b but this doesn't $ test -z "$x" -a a = b bash: test: too many arguments because it groups "test -n = -a" and is left with "a = b". Similarly, if $x is "-f", these $ test "$x" $ test "$x" || test c = d correctly adds an implicit "-n", but this fails: $ test "$x" -o c = d bash: test: too many arguments Signed-off-by: Elia Pinto <gitter.spi...@gmail.com> --- Inspired from this discussion http://permalink.gmane.org/gmane.comp.version-control.git/137056 git-submodule.sh | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/git-submodule.sh b/git-submodule.sh index b55d83a..d89e1d0 100755 --- a/git-submodule.sh +++ b/git-submodule.sh @@ -864,7 +864,7 @@ Maybe you want to use 'update --init'?")" then subforce=$force # If we don't already have a -f flag and the submodule has never been checked out - if test -z "$subsha1" -a -z "$force" + if test -z "$subsha1" || test -z "$force" then subforce="-f" fi @@ -1059,13 +1059,13 @@ cmd_summary() { while read mod_src mod_dst sha1_src sha1_dst status sm_path do # Always show modules deleted or type-changed (blob<->module) - test $status = D -o $status = T && echo "$sm_path" && continue + ( test $status = D || test $status = T ) && echo "$sm_path" && continue # Respect the ignore setting for --for-status. if test -n "$for_status" then name=$(module_name "$sm_path") ignore_config=$(get_submodule_config "$name" ignore none) - test $status != A -a $ignore_config = all && continue + test $status != A && test $ignore_config = all && continue fi # Also show added or modified modules which are checked out GIT_DIR="$sm_path/.git" git-rev-parse --git-dir >/dev/null 2>&1 && @@ -1125,7 +1125,7 @@ cmd_summary() { *) errmsg= total_commits=$( - if test $mod_src = 160000 -a $mod_dst = 160000 + if test $mod_src = 160000 && test $mod_dst = 160000 then range="$sha1_src...$sha1_dst" elif test $mod_src = 160000 @@ -1162,7 +1162,7 @@ cmd_summary() { # i.e. deleted or changed to blob test $mod_dst = 160000 && echo "$errmsg" else - if test $mod_src = 160000 -a $mod_dst = 160000 + if test $mod_src = 160000 && test $mod_dst = 160000 then limit= test $summary_limit -gt 0 && limit="-$summary_limit" @@ -1233,7 +1233,7 @@ cmd_status() say "U$sha1 $displaypath" continue fi - if test -z "$url" || ! test -d "$sm_path"/.git -o -f "$sm_path"/.git + if test -z "$url" || ! test -d "$sm_path"/.git || test -f "$sm_path"/.git then say "-$sha1 $displaypath" continue; @@ -1402,7 +1402,7 @@ then fi # "--cached" is accepted only by "status" and "summary" -if test -n "$cached" && test "$command" != status -a "$command" != summary +if test -n "$cached" && test "$command" != status && test "$command" != summary then usage fi -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
