It supports compression and decompression of individual files, as well as streaming compression and decompression via standard input and output. .Pp The default operation is compression, decompression can be selected by supplying the .Fl d flag on the commandline. .Pp If any .Ar file arguments are supplied, the operation is performed on each file separately. Compression replaces the original file with one having a .Pa .gz suffix. Decompression will remove a .Pa .gz suffix if one is present. .Pp If no .Ar file arguments are supplied, .Nm reads from standard input and writes the results of the operation to standard output. .Sh SEE ALSO .Xr gzip 1 .Sh AUTHORS .Nm Minigzip was written by .An Jean-loup Gailly .
