Top Forums Shell Programming and Scripting Reason for no directory creation date Post 303029120 by Don Cragun on Monday 21st of January 2019 06:28:44 PM

Most file system types used on BSD, Linux, and UNIX systems do not save a timestamp indicating when a file was created (and a directory is one type of a "file"). If a frequently used file system type on your system does save file creation timestamps, there is probably an option on the ls utility on your system that will print files' creation dates instead of the last modification time of the file's contents (default), last modification time of the file's metadata (-c option), or the last access time of the file (-u option) when printing a long listing (-l option).

You'll have to check the man page for ls on your system to determine whether or not your system provides such an option and what filesystem types support it, if it does.

SYSFS(2)                                                     Linux Programmer's Manual                                                    SYSFS(2)

NAME
sysfs - get filesystem type information SYNOPSIS
int sysfs(int option, const char *fsname); int sysfs(int option, unsigned int fs_index, char *buf); int sysfs(int option); DESCRIPTION
Note: if you are looking for information about the sysfs filesystem that is normally mounted at /sys, see sysfs(5). The (obsolete) sysfs() system call returns information about the filesystem types currently present in the kernel. The specific form of the sysfs() call and the information returned depends on the option in effect: 1 Translate the filesystem identifier string fsname into a filesystem type index. 2 Translate the filesystem type index fs_index into a null-terminated filesystem identifier string. This string will be written to the buffer pointed to by buf. Make sure that buf has enough space to accept the string. 3 Return the total number of filesystem types currently present in the kernel. The numbering of the filesystem type indexes begins with zero. RETURN VALUE
On success, sysfs() returns the filesystem index for option 1, zero for option 2, and the number of currently configured filesystems for option 3. On error, -1 is returned, and errno is set appropriately. ERRORS
EFAULT Either fsname or buf is outside your accessible address space. EINVAL fsname is not a valid filesystem type identifier; fs_index is out-of-bounds; option is invalid. CONFORMING TO
SVr4. NOTES
This System-V derived system call is obsolete; don't use it. On systems with /proc, the same information can be obtained via /proc/filesystems; use that interface instead. BUGS
There is no libc or glibc support. There is no way to guess how large buf should be. COLOPHON
