NAME

zcat − decompress and concatenate files to standard output

SYNOPSIS

zcat [options] [files]

DESCRIPTION

Zcat copies each given file to standard output. If any given file is compressed, its decompressed content is used. If a given file does not exist, and its name does not end with one of the known extensions, zcat tries the compressed file names corresponding to the supported formats.

If no files are specified, or if a file is specified as ’−’, data are read from standard input, decompressed if needed, and sent to standard output. Data read from standard input must be of the same type; all uncompressed or all in the same compression format.

The supported formats are bzip2, gzip, lzip and xz.

Exit status is 0 if no errors occurred, non−zero otherwise.
