In BASH how do I list all files older than 1000 days?

Hello,

Have a look at the man page for find, more in particular the -mtime and -atime parameters.

Code:

man find

Kind regards,

Eric

One of the most confusing man pages ever. For me anyway. I really needed a chart and graph to grasp the -x, x and +x of mtime.

Hi,

It is indeed pretty complex (but also complete) but after reading what you need like 4 times it becomes clear.

Kind regards,

Eric

The problem is that I need the kind of information that ls gives, e.g., date, owner.

Also, the find command chokes on some files (it stopped on a rather large .mov file

Hello,

Have a look at the man page for ls:

Code:

-c     with -lt: sort by, and show, ctime (time of  last  modification  of  file
             status  information) with -l: show ctime and sort by name otherwise: sort
             by ctime

That will sort your files by last modification time for example. From there you'd have to use some more scripting to calculate if the last modification time exceeds your limit of 1000 days.

Kind regards,

Eric

Try this (it will fail if there are a very large number of files)

Code:

ls -l $( find / -mtime +1000 )

Are you sure about find choking? It is very robust.
