In the man of find the -ctime is said to be :
-ctime n
File status was last changed n*24 hours ago. See the comments
for -atime to understand how rounding affects the interpretation
of file status change times.
-atime n
File was last accessed n*24 hours ago. When find figures out
how many 24-hour periods ago the file was last accessed, any
fractional part is ignored, so to match -atime +1, a file has to
have been accessed at least two days ago.
I know from here that the ext4 file system stores the creation date , and you can get it using stats , is the status change times they are talking about in the manual the same as the one given by stats ? or precisely , is the ctime the date of creation of a file ?
-ctime +30will not work ? – Kingofkech Oct 18 '17 at 12:59
