* this code works ony with x86 and x86_64 */ does not (yet) provide a wrapper for the statx() system call You can compile the statx.c code, or, if you just want the birth time, create a birth.c in the cloned directory with the following code (which is a minimal version of statx.c printing just the creation timestamp including nanosecond precision): #define _GNU_SOURCE Its output is the same format as stat's default, without any formatting options, but it's simple to modify it to print just the birth time.

On 18.10 and newer, you can directly use the statx function as described in man 2 statx (note that the 18.10 manpage is incorrect in stating that glibc hasn't added the wrapper yet).Īnd in Ubuntu 20.10, you will be able to use stat directly: # stat -versionĬopyright (C) 2020 Free Software Foundation, Inc. So, I don't expect stat on any current LTS release (16.04, 18.04 or 20.04) to ever print the creation time without manual intervention. The stat command itself gained support for statx(2) only in GNU coreutils 8.31 (released in March 2019), however, even Ubuntu 20.04 only has coreutils 8.30.īut I don't think this will be backported to LTS releases even if they do get, or are already on, newer kernels or glibcs.
Typically glibc provides a wrapper that makes the job easy, but glibc only added a wrapper for statx(2) in August 2018 (version 2.28, available in 18.10). Unfortunately, it's not easy to call system calls directly in a C program. Check uname -r to see if you are using a kernel at least at 4.11 to confirm. * And possibly on older LTS releases using the hardware enablement stack (HWE) kernels.
Starting with Linux 4.11 (i.e., 17.10 and newer*), however, the new statx(2) system call is available, which does include a creation time in its return struct. The inability of stat to show the creation time is due to limitation of the stat(2) system call, whose return struct doesn't include a field for the creation time.
