ls -?????

Looking for a way to list (ls) based on mod/create date. The closest I’ve come is something like (ls –ltr). This of course returns all files in a given directory. If anyone is familiar with VMS it would be equivalent to (dir/sin). I’m trying to incorporate this into a ftp script that deals with exact reoccurring file names.

You want find

Suppose you want everything from Sep 1 on ... use touch

This finds files with a mod date newer than t.file

And -

NB there is no create date in Unix only:

1. last access
2. last modify
3. last inode change (permissions change, ownership change etc on file)

That actually works great however the question is a little deeper and involves more FTP logic. I've actually created a script containing your suggestions and aliased it to a new command within my environment. It works great. I'm going to try and include my code for future forum reference. Feel free to pick it apart.

That script does a (in VMS like terms) DIR/SINCE=START_OF_THIS_MONTH.
You may want something more flexible:

try www.unix.com - there are some "FAQ" tutorials one on the find command. one on date arithmetic:
