2013-01-02test: Add check-non-portable-shell.plLibravatar Torsten Bögershausen1-0/+27
Add the perl script "check-non-portable-shell.pl" to detect non-portable shell syntax. "echo -n" is an example of a shell command working on Linux, but not on Mac OS X. These shell commands are checked and reported as error: - "echo -n" (printf should be used) - "sed -i" (GNUism; use a temp file instead) - "declare" (bashism, often used with arrays) - "which" (unreliable exit status and output; use type instead) - "test a == b" (bashism for "test a = b") "make test-lint-shell-syntax" can be used to run only the check.
