From 832ac79edf0e0e9108f5da5b10b496a227667f40 Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Mon, 21 Jun 2010 12:37:13 -0500 Subject: [PATCH] t/lib-pager.sh: remove unnecessary '^' from 'expr' regular expression Regular expressions matched by 'expr' have an implicit '^' at the beginning of them and so are anchored to the beginning of the string. Using the '^' character to mean "match at the beginning", is redundant and could produce the wrong result if 'expr' implementations interpret the '^' as a literal '^'. Additionally, GNU expr 5.97 complains like this: expr: warning: unportable BRE: `^[a-z][a-z]*$': using `^' as the first character of the basic regular expression is not portable; it is being ignored Signed-off-by: Brandon Casey Signed-off-by: Junio C Hamano --- t/lib-pager.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/t/lib-pager.sh b/t/lib-pager.sh index f8c602587..ba03eab14 100644 --- a/t/lib-pager.sh +++ b/t/lib-pager.sh @@ -9,7 +9,7 @@ test_expect_success 'determine default pager' ' test -n "$less" ' -if expr "$less" : '^[a-z][a-z]*$' >/dev/null +if expr "$less" : '[a-z][a-z]*$' >/dev/null then test_set_prereq SIMPLEPAGER fi -- 2.26.2
