I want to delete *.txt and not create Aug.
# ls -al | egrep -v Aug | egrep .txt
-rw-r--r--    1 root     root            0 Jul 11 12:12 1.txt

But How do I delete use "rm" command?

P.S I know this know-how
# ls -al | egrep -v Aug | egrep .txt | awk '{ print $8}' >  aaa.txt
   and included rm -f in aaa.txt

rm -f `ls -al | egrep -v Aug | egrep .txt | awk '{ print $8}' `

but this could be optimised quite a bit...

rm -f `ls -al *.txt | awk '/Aug/{print $8}'`

Creation date is not stored on a unix system, ls -l displays the time of
last modification.

find can be used to find files with an mtime in the last 'x' days and can
also be used to find file 'not' modified in the last 'x' days.

As an alternative to this you can also find things newer than a particular
file or older than a particular file using the -newer argument.

Hope this helps some,
Adam

2.  ls -l *.txt | awk '/Aug/' {print $9} | while read i; do
        rm $i
    done

3.  rm `ls -l *.txt | awk '/Aug/' {print $9}`

4.  find -maxdepth -daystart -mtime +12 -name '*.txt' | xargs rm
