Script+Shell: fixed and standardize PATH checking We redirect stderr to NULL since POSIX says it may be used (no modern shell seems to be using it). If more than 1 program is checked for availability, we use a function. Emacs snippet make it uniform. Error message is output on stderr and is always the same. 2014-01-03 19:13:07 +01:00			`if command -v greadlink >/dev/null 2>&1; then`
