.TH ZCAT "1" "February 2018" "zcat (zutils) 1.7" "User Commands"
.SH NAME
zcat \- decompress and concatenate files to standard output
.SH SYNOPSIS
.B zcat
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH 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.
.PP
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.
.PP
The supported formats are bzip2, gzip, lzip and xz.
.PP
Exit status is 0 if no errors occurred, non\-zero otherwise.
