|
.SH NAME
|
|
zcat \- decompress and concatenate files to standard output
|
|
.SH SYNOPSIS
|
|
.B zcat
|
|
[\fIoptions\fR] [\fIfiles\fR]
|
|
.SH DESCRIPTION
|
|
Zcat copies each given file ("\-" means standard input), 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,
|
|
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 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.
