No, the "$@" needs to be at the end:
// 2>/dev/null ; exec tcc -run "$0" "$@"
#include <stdio.h>
int main (int argc, char **argv)
{
int i;
for (i = 0; i < argc; i++)
printf ("argv[%d]: %s\n", i, argv[i]);
return 0;
}
$ ./args.c ab cd
argv[0]: ./args.c
argv[1]: ab
argv[2]: cd
Otherwise this gives
tcc: error: file 'ab' not found
