ZCAT(1) User Commands ZCAT(1) 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 until one is found. 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, de- compressed if needed, and sent to standard output. Data read from stan- dard 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 work- ing 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.
