To print the pathname that will be used by shell in the current environment, 'command -v' is a standardized way. [1]
'which' is also often used in scripting, but it is not portable.
All uses of 'which' should be expunged. It is a bourne shell script that is trying to emulate a csh builtin. It is doomed to fail in corner cases. ISTR it has serious problems with shell functions and aliases.
