2 Sample output

Here are some realistic examples of running gzip.

This is the output of the command ‘gzip -h’:

     Usage: gzip [OPTION]... [FILE]...
     Compress or uncompress FILEs (by default, compress FILES in-place).
     Mandatory arguments to long options are mandatory for short options too.
       -c, --stdout      write on standard output, keep original files unchanged
       -d, --decompress  decompress
       -f, --force       force overwrite of output file and compress links
       -h, --help        give this help
       -k, --keep        keep (don't delete) input files
       -l, --list        list compressed file contents
       -L, --license     display software license
       -n, --no-name     do not save or restore the original name and time stamp
       -N, --name        save or restore the original name and time stamp
       -q, --quiet       suppress all warnings
       -r, --recursive   operate recursively on directories
       -S, --suffix=SUF  use suffix SUF on compressed files
       -t, --test        test compressed file integrity
       -v, --verbose     verbose mode
       -V, --version     display version number
       -1, --fast        compress faster
       -9, --best        compress better
     With no FILE, or when FILE is -, read standard input.
     Report bugs to <>.

This is the output of the command ‘gzip -v texinfo.tex’:

     texinfo.tex:     69.3% -- replaced with texinfo.tex.gz

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/^\\(.*\\)\\.gz$/gunzip <'\\1.gz' >'\\1'/
       " |
       sh -e
