.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 file argument to standard output in sequence. If any
file given is compressed, its decompressed content is copied. If a file
given does not exist, and its name does not end with one of the known
extensions, zcat tries the compressed file names corresponding to the
formats supported until one is found. If a file fails to decompress, zcat
continues copying the rest of the files.
.PP
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 compressed format.
.PP
If no files are specified, recursive searches examine the current
working directory, and nonrecursive searches read standard input.
.PP
The formats supported are bzip2, gzip, lzip, xz, and zstd.
.PP
Exit status is 0 if no errors occurred, 1 otherwise.
