I have a zip file which I want to split into multi gzip files. I don't need the actual file on disk and prefer to keep everything in memory so it will be faster. was thinking maybe:
split -C 2M -d -a 3 --filter 'gzip > $FILE.gz' <(unzip a.zip ) a_
or unzip -c a.zip | split -C 2M -d -a 3 --filter 'gzip > $FILE.gz' a_
But it gzip the output of the unzip:
Archive: a.zip
inflating: data.txt
And on the second option it fails
split: cannot open ‘a_’ for reading: No such file or directory
-c -q is the answer
split -C 2M -d -a 3 --filter 'gzip > $FILE.gz' <(unzip -c -q a.zip ) a_
