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 <stdio.h>
#include <unistd.h>
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
