Hi

I think you got confused ..i need a sheel script to run in unix.

 

[jad]

assuming that <RDRIVE> is defined to be the same location as 'R:' in windows

#!/bin/sh
RDRIVE=<RDRIVE>;
cd ${RDRIVE}/Image/batch
rm `cat ../history.txt`
cat /dev/null > ../history.txt

put above text in a file called '<something>.sh' and chmod +x <something.sh>
then add an entry in your crontab to run it every saturday.

sorry jad, too easy!

#!/bin/sh
RDRIVE=<RDRIVE>; # i agree
cd ${RDRIVE}/Image/batch # [{}] are not needed
rm `cat ../history.txt` # get problems with metachar
cat /dev/null > ../history.txt # will destroy ../history.txt
------------
assuming the '>' are (stupid) tabs and '\' are what unix '/' means, you can do:
------------

cd what-ever-you-want

list the-folder >>history.txt

for element in 'sort -u history.txt'
do
[ -f $element ] || continue # no files found called $element
rm -f $element
sed -e &quot;/$element/d&quot; history.txt >xxx
[ -f xxx ] || exit 1 # error encontered xxx does not exists
mv xxx history.txt
done
------------
no idea what with '\' appens, you have my be to mask it using tr|sed|or-what-you-want

If the file does not exist, the previous code (sorry jamisar) will not remove the name from the history file, so the first line does not meet your requirements, try the following if you dont want to completely clear out the history file:

for element in 'sort -u history.txt'
do
rm -f $element
sed -e &quot;/$element/d&quot; history.txt > history.tmp
[ -f xxx ] || exit 1
mv history.tmp history.txt
done

If you actually want to throw the history file away each time this script is run, try this:

for element in `cat history.txt`
do
rm -f $element
done
rm history.txt

If you want the history file to be empty but still exist, then replace the last line with:

cat /dev/null > history.txt
