a typical ls output looks like this...
-rw-r----- 1 ltaber wheel 1876 Mar 28 16:55 tmp
assuming the time stamp is the 8th field and file is 9 th field (check this out)
I don't have UNIX shell with me at present... but try listing with this loop...
----------------------------------------------------------
for lsout in `ls -l`
do
hours=`echo $lsout | cut -d " " -f 8 | cut -d ":" -f 1`
filetodelete=`echo $lsout | cut -d " " -f 9`
if [ $hours -lt 19 -o $hours -ge 20 ]
then
echo $filetodelete
fi
done
----------------------------------------------------------
I hope you got what I'm trying to do...
if the above code lists the files you wanted to delete ( you may need to make some modifications )... you can replace the echo with a "rm -f $filetodelete"
the above scheme will work if none your files are older than 6 months.. because ls -l will not list time stamp if a file is older than 6 months... also I assume that none of your files is having spaces in its name...
wish to see better ways for this...
Cheers!
Vishnu.

WORDWRAP(3) 1 WORDWRAP(3)
wordwrap - Wraps a string to a given number of characters
SYNOPSIS
string wordwrap (string $str, [int $width = 75], [string $break = "0], [bool $cut = false])
DESCRIPTION
Wraps a string to a given number of characters using a string break character.
PARAMETERS
o $str
- The input string.
o $width
- The number of characters at which the string will be wrapped.
o $break
- The line is broken using the optional $break parameter.
o $cut
- If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger
than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width
is smaller than the word width.
RETURN VALUES
Returns the given string wrapped at the specified length.
