Compress the contents of a directory while copying data into it
Hi guys

I have a need to compress the contents of a directory while I am copying data into it. I was able to do this when it was only one file by doing as below:

STEP1: mknod myfile p

STEP2: chmod 777 myfile

STEP3: compress -v < myfile > myfile.Z &

STEP4: cp -p xyz_file myfile

STEP5: rm myfile

But now my requirement is to have multiple files copied into a directory and compress while the copying is happening so that I dont use a lot of space. Can anyone of you give me some idea of how I can achieve this. For example I want to copy the contents of a directory called source (has file1, file2, file3 and file4) to backup.

Thanks in advance.

Regards

RB

How about...
Quote:
for f in *
do
mknod ${f}_pipe p
chmod 777 ${f}_pipe
compress -v < ${f}_pipe > ${f}.Z &
cp -p $f ${f}_pipe
rm ${f}_pipe
done

Thanks Jerry

But my requirement is to compress the entire directory and not individual files. Although compressing individual files does the job, I will have to make several changes to already existing procedures and scripts for restoring data from the backups, if need arise.

Again thanks for your reply.
