NAME¶

Zcat - decompress and concatenate files to standard output

SYNOPSIS¶

zcat [ options] [files]

DESCRIPTION¶

Zcat copies each given file ("-" means standard input), to standard output. If any given file is compressed, its uncompressed 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 compressors. If no files are specified, data is 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 compressed with the same compressor. The supported compressors are bzip2, gzip, lzip and xz. Exit status is 0 if no errors occurred, 1 otherwise.
