To be precise, $0 always contains the path to the program called. You are right, this path will change depending on location from which the program was called. So $0 is OK for my case, while current directory is unrelated.

Actually it contains whatever was passed to exec. By convention this is program name but it could be anything #include #include int main(int argc, char** argv) { if( argc != 1 ) { printf("%i: %s\n", argc, argv[0] ); } else { execl("./argv","Random junk","",0); } return 0; } $ gcc argv.c -o argv && ./argv 2: Random junk

Try this:

#!/bin/sh echo "Arg 0: $0" echo "All Parameters: [$@]"

Again, any way to get the same functionality in GHC?

getArgs and getProgName should do the trick http://hackage.haskell.org/packages/archive/base/latest/doc/html/System-Envi...
