[Help-tar] Amending contents of absolute-path tar files without extracting to root dir

[Nick Lewis]

Can someone please suggest a solution to my tar problem

 

I have tars that contain files with absolute paths and wish to replace some of the files. However I do not wish to extract all the files into the root directory as this will adversely affect operation of my computer. Therefore I wish to extract the files to a subdirectory, make the desired replacements and tar it all up again with the paths appearing as before. Is there something like a --make-absolute tar option that will prefix the filenames with a slash? If not is there a grep/sed script that could reliably find path names in the tar and slash prefix them?

 

Best Regards

Nick
