zcat — expand and concatenate data
Синопсис (Synopsis)
zcat [file...]
Описание (Description)
The zcat utility shall write to standard output the uncompressed
form of files that have been compressed using the compress
utility. It is the equivalent of uncompress -c. Input files are
not affected.

Операнды (Operands)
The following operand shall be supported:
file The pathname of a file previously processed by the
compress utility. If file already has the .Z suffix
specified, it is used as submitted. Otherwise, the .Z
