TAR and GZIP help

Hi,

There are 700 .pdf files in a certain directory on the server and I need to TAR them first and then compress them using GZIP to free up the space. The combined size of the .pdf files is 3gb. However, there is only 1gb of free space on the server. So as you can see when I try to TAR these files, it fails.
Any idea on how to resolve this problem? Smilie

The only constraint here besides the space on the server is that I need to .TAR the files first and then do the compression using GZIP.

Any help you can provide will be much appreciated. Thank you! Smilie

A possible approach given in this thread - extract from TAR

You might have to reverse the logic.

It really depends on whether the gzipped tar file will be less than the 1gb of free space you currently have. If so then

Code:
tar cvf - {file list} | gzip -c > all-pdfs.tar.gz

Of if you have GNU tar then simply

Code:
tar zcvf all-pdfs.tar.gz {file list}

Alternatively you could make a list of pdf files in, say, 500gb chunks and use the 'r' flag on tar to add them to an existing archive. eg

Code:
# Creat initial archive
tar cvf all-pdfs.tar {1st file list}
rm {1st file list}

# Add files to archive
tar rvf all-pdfs.tar {2nd file list}
rm {2nd file list}
tar rvf all-pdfs.tar {3rd file list}
rm {3rd file list}
etc ..

Unbeliever
