[SOLVED] find /tmp -xdev -type f -printf "%Ts %p\n" Why does it work?

Hi: The following command prints the file modification time in seconds since 1970-01-01 00:00:00:

Code:

find /tmp -xdev -type f -printf "%Ts %p\n"

However, I can't find the 's' in the format string in the find(1) man page. The find version is 4.4.2, the one that comes with Slackware 14.0. Do you know where I can find it documented?

The letter after %T is passed to the C function strftime, so find handles whatever characters there that strftime does. (They aren't all documented under find, because strftime can vary from system to system.) See man 3 strftime, where %s means seconds since epoch.

Thank you very much. By the way, is there any way to print a file's date in the same fashion with ls? I mean, seconds from 1970?

Code:

ls -l --time-style=+%s
