How do you gunzip a file and keep the .gz file?
You're looking for:
gzcat x.txt.gz >x.txt
The gzcat
command is equivalent to gunzip -c
which simply writes the output stream to stdout
. This will leave the compressed file untouched. So you can also use:
gunzip -c x.txt.gz >x.txt
Note that on some systems gzcat is also known as zcat
so run like this instead:
zcat x.txt.gz >x.txt
You can use the -c
option of gunzip which writes the output to stdout, and then pipe it to the file of your choice:
gunzip -c compressed-file.gz > decompressed-file
More details on the manual page.
A simpler solution is to just use gunzip as a filter like this:
gunzip < myfile.gz > myfile
