Hi Bug-Gzip. On the info page for Gzip it says:
The following command will find all regular `.gz' files in the current directory and subdirectories (skipping file names that contain newlines), and extract them in place without destroying the original, stopping on the first failure: find . -name '* *' -prune -o -name '*.gz' -type f -print | sed " s/'/'\\''/g s/^\\(.*\\)\\.gz$/gunzip <'\\1.gz' >'\\1'/ " | sh -e But that seems not to be the case. I just tried: mkdir '12" records' echo > '12" records'/"Beatles' Greatest" echo > '12" records/> Groovy stuff <' gzip -r . and then running above. That did not work. Probably because of quotes, spaces, < and > in filenames. May I suggest you change it to: The following command will find all regular `.gz' files in the current directory and subdirectories, and extract them in place without destroying the original, running one gunzip process per CPU in parallel: find . -name '*.gz' -type f -print0 | parallel -0 -j+0 gunzip "<{}" ">{.}" This would do The Right Thing - even if the names contain newlines, quotes, <, > or other obscenities. Some may even find it more readable. Parallel is available here: http://www.gnu.org/software/parallel/ /Ole
