utility.
Finds the first instance of a specified executable in the PATH environment variable. Does not cache the results, so hash -r

path
: Use instead of the PATH
environment variable.pathExt
: Use instead of the PATHEXT
environment variable.all
: Return all matches, instead of just the first one. Note that this means the function returns an array of strings instead of a single string.
