gzip complains with trailing garbage ignored



Some tar.gz files are padded with zeroes to have a size
which is a multiple of a certain block size. This occurs in particular
when the compressed tar file is on a device such as a
magnetic tape.  When such files are extracted with a command such as



    gunzip 

gunzip decompresses correctly the tar.gz file, then
attempts to decompress the rest of the input which consists of zeroes.
Since those zeroes are not in gzip format, gzip
ignores them. The tar extract command still works correctly,
since gzip has sent through the pipe all the data that tar
needs.



You can avoid this harmless warning by using the -q
option of gzip, as in:




    gunzip -q
