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-rebase--interactive.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/git-rebase--interactive.sh b/git-rebase--interactive.sh index 6ec9d3c..797571f 100644 --- a/git-rebase--interactive.sh +++ b/git-rebase--interactive.sh @@ -1013,7 +1013,7 @@ then git rev-list $revisions | while read rev do - if test -f "$rewritten"/$rev -a "$(sane_grep "$rev" "$state_dir"/not-cherry-picks)" = "" + if test -f "$rewritten"/$rev && test "$(sane_grep "$rev" "$state_dir"/not-cherry-picks)" = "" then # Use -f2 because if rev-list is telling us this commit is # not worthwhile, we don't want to track its multiple heads, -- 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
