From: Torsten Bögershausen <[email protected]> Some implementations of `echo` support the '-e' option to enable backslash interpretation of the following string. As an addition, they support '-E' to turn it off.
However, none of these are portable, POSIX doesn't even mention them, and many implementations don't support them. A check for '-n' is already done in check-non-portable-shell.pl, extend it to cover '-n', '-e' or '-E-' Signed-off-by: Torsten Bögershausen <[email protected]> --- t/check-non-portable-shell.pl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/t/check-non-portable-shell.pl b/t/check-non-portable-shell.pl index b170cbc045..03dc9d2852 100755 --- a/t/check-non-portable-shell.pl +++ b/t/check-non-portable-shell.pl @@ -17,7 +17,7 @@ sub err { while (<>) { chomp; /\bsed\s+-i/ and err 'sed -i is not portable'; - /\becho\s+-n/ and err 'echo -n is not portable (please use printf)'; + /\becho\s+-[neE]/ and err 'echo with option is not portable (please use printf)'; /^\s*declare\s+/ and err 'arrays/declare not portable'; /^\s*[^#]\s*which\s/ and err 'which is not portable (please use type)'; /\btest\s+[^=]*==/ and err '"test a == b" is not portable (please use =)'; -- 2.14.1.145.gb3622a4ee9
