View Full Version : Bash question

October 1st, 2008, 03:41 AM
When we perform a "-N" test for a file using bash, does bash keep the information about the last time the file was read on a peruser basis or does it just use the last modified time of the file and compare it with the last accessed time?

From bash's test.c

case 'N':
return (sh_stat (arg, &stat_buf) == 0 &&
stat_buf.st_atime <= stat_buf.st_mtime);

Looks like it's using the atime and mtime.

Ah thanks. Where do you get the bash source from?

At http://ftp.gnu.org/gnu/bash/ or

apt-get source bash
