The problem is, the while loop seems to have a problem with the spaces.

You've got two things deserving comments in above:
- the OFS variable has a meaning in awk (only / mostly). for shell, use IFS.
- as your v2 variable holds the remainder of the input line, i.e. 577 sjreas.py, I'd be surprised if the printf command only outputted a space, and not the file name, because, due to the quoting, everything would be the first parameter to printf and thus its "format string".

NAME
explain_printf_or_die - formatted output conversion and report errors SYNOPSIS
#include <libexplain/printf.h> int explain_printf_or_die(const char *format); int explain_printf_on_error(const char *format); DESCRIPTION
The explain_printf_or_die function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_printf_on_error function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, but still returns to the caller. format The format, exactly as to be passed to the printf(3) system call. RETURN VALUE
The explain_printf_or_die function only returns on success, see printf(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_printf_on_error function always returns the value return by the wrapped printf(3) system call. EXAMPLE
The explain_printf_or_die function is intended to be used in a fashion similar to the following example: int result = explain_printf_or_die(format); SEE ALSO
printf(3) formatted output conversion explain_printf(3) explain printf(3) errors exit(2) terminate the calling process COPYRIGHT
