Well, It is not env fault. The problem is the activation of a file with the magic `#!'. The invocation is different among UNIXes, but it won't do what you want on any of them. On Linux and Cygwin (and may be other GNU systems) this magic produce the following effect: argv[0] = string after the #! with whitespaces striped. argv[1] = rest of the line AS IS (whitespaces striped from both sides) srgv[2] = name of the invoked file (relative or absolute depending on how the file is called by the executing command). On DG/UX and Solaris (as reported by Bob McGowan ) argv[1] is the 2nd string (between spaces, AS IS), the test of the line is ignored. You can easily check it by changing the 1st line to #! /bin/echo ....
