Defined in packages/acs-tcl/tcl/utilities-procs.tcl

Use environment variable PATH to search for the specified executable program. Replacement for UNIX command "which", avoiding exec. exec which: 3368.445 microseconds per iteration ::util::which: 282.372 microseconds per iteration In addition of being more than 10 time faster than the version via exec, this version is less platform dependent.

Parameters:
prog (required)
name of the program to be located on the search path
Returns:
fully qualified name including path, when specified program is found, or otherwise empty string
