Hi when trying to find files by date, this command usto work and it has just suddenly stopped. Am I typing it correctly ? any help ? The command is

find /dev/fs/E/XXXX/XXX/product -type d -ctime +14 -print

There are files and directories below product but the command can not seem to see them. What am I missing. Thanks

Troy

> Hi when trying to find files by date

The command you give isn't going to find _files_ by date. It's going to find directories.
For finding files you want to pass "f" as the operand to the '-type' option.

Rodney thanks for the answer, I actually wrote files but I did mean files or directories, so if the operand if f it looks for files and if it were d it should find directories? it works with f but not with d any thoughts why ? Thanks

Sure, you asked for 'ctime'. That'll look at the stat field that's returned with
stat(2). Refer to that man page: ctime is "time of last file status change".
This field doesn't change often. Usually 'mtime' and 'atime' change more often with
files.

If you want to check for both files and directories at the same time with
the '-or' expression/option with find. So:

 find /dev/fs/E/XXXX/XXX/product -type d -or -type f -mtime 14 -print

Important quote from stat(2) man page:

    st_atime
        Time when file data last accessed. Changed by the utime(2) and read(2
        calls.

    st_mtime
        Time when file data last modified. Changed by the utime(2) and
        write(2) calls.

    st_ctime
        Time when file status was last changed (file serial data
        modification). Changed by the chmod(2), chown(2), link(2), rename(2),
        unlink(2), utime(2) and write(2) calls.

The other key aspect here is the type of underlying filesystem. If you are
making reference (/dev/fs/E/...) to an local NTFS disk or an NFS disk that
references NTFS, FFS or UFS then these stat fields are going to be good.
But(!) if it's an SMB (aka Samba) or FAT forget it. Some of these field
values are getting faked because the protocol doesn't support this info.
