NAME

       zcat - decompress and concatenate files to standard output

SYNOPSIS

       zcat [options] [files]

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. If a file  fails  to  decompress,  zcat  continues
       copying the rest of the files.

       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.

       If  no  files are specified, recursive searches examine the current working directory, and
       nonrecursive searches read standard input.

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

       Exit status is 0 if no errors occurred, 1 otherwise.
