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
