I have a directory full of *.txt files. I would like to print the last line of every file to screen.
I know you can use FNR for printing the first line of each file, but how do I access the last line of each file?
This code doesn't work, it only prints the last line of the last file:BEGIN... (5 Replies)

XPRINTF_COMP(3) BSD Library Functions Manual XPRINTF_COMP(3)NAME
free_printf_comp, new_printf_comp -- extensible printf compilation
SYNOPSIS
#include <printf.h>
void
free_printf_comp(printf_comp_t pc);
printf_comp_t
new_printf_comp(printf_domain_t restrict domain, locale_t restrict loc, const char * restrict fmt);
DESCRIPTION
To ameliorate some of the slowness caused by the extra overhead in extensible printf (see xprintf(5)), a compile/execute mechanism has been
created. The new_printf_comp() function compiles the given format string, along with a printf domain (see xprintf_domain(3)) and an extended
locale (see xlocale(3)), and returns a printf_comp_t structure. The domain may not be NULL, but the locale can be NULL, which means to use
the current locale, either the per-thread locale if it was set, or else the global locale. Because the printf_comp_t structure records the
domain and locale, care should be taken if either of these are changed.
Once a printf_comp_t structure is created, it can be passed to one of the extensible printf execution variants, described in xprintf_exec(3),
along with the necessary arguments. Creating the printf_comp_t structure needs to be done only once, but it can be passed to extensible
printf execution variants any number of times.
When the printf_comp_t structure is no longer needed, it should be passed to free_printf_comp() to release internal memory.
RETURN VALUES
The new_printf_comp() function returns the new structure, or NULL on error (usually NULL domain or out of memory condition).
