Delete files returned by ls
I need to delete the files that are returned by this ls command:

Code:
root@16:06:37@whci03:/var/log/whci# ls -ltrhS | grep "Apr  [234]"
-rw-r--r-- 1 whci  users 180M Apr  4 00:00 20090403_whci_Access.txt
-rw-r--r-- 1 whci  users 185M Apr  4 00:00 20090403_whci_Access.txt
-rw-r--r-- 1 whci  users 189M Apr  4 00:00 20090403_whci_Access.txt
-rw-r--r-- 1 whci  users 190M Apr  2 00:00 20090401_whci_Access.txt
-rw-r--r-- 1 whci  users 193M Apr  2 00:00 20090401_whci_Access.txt
-rw-r--r-- 1 whci  users 194M Apr  2 00:00 20090401_whci_Access.txt
-rw-r--r-- 1 whci  users 201M Apr  3 00:00 20090402_whci_Access.txt
-rw-r--r-- 1 whci  users 204M Apr  3 00:00 20090402_whci_Access.txt
-rw-r--r-- 1 whci  users 205M Apr  3 00:00 20090402_whci_Access.txt

I tired:
Code:
ls -ltrhS | grep "Apr  [234]" | rm -f

but I got the following error msg:

rm: invalid option -- w
Try `rm --help' for more information.

Try this.....(although there might be a better way)


Code:
ls -ltrhS | grep "Apr  [2-4]" | awk -F' ' '{print $9}' | xargs rm -f

You can't pass the output of 'ls -ltrhS' into rm, you only need the filename


EDIT:
Actually if you think about it....without the AWK the rm command looks like this(which is invalid):
Code:
rm -rw-r--r-- 1 whci  users 205M Apr  3 00:00 20090402_whci_Access.txt

Should be:

rm -f 20090402_whci_Access.txt

That's where you were getting the 'invalid option --w'.

Make sense?

use the find command to find the file(s) and remove them....

find *whci_Access.txt -mtime +10 -exec rm {} \;

this will find all files with the name *whci_Access.txt older than 10 days and remove them.
