# zzcat(1)

small tools using zziplib

Part of [zziplib-bin(1)](/zziplib-bin/1.md).

## NAME

zzcat, zzdir, zzxorcat, zzxordir zzxorcopy - small tools using zziplib

## SYNOPSIS

**zzcat FILE \[...\]** **zzdir DIR \[...\]** **zzxorcat \[-HEX\] FILE \[...\]** **zzxordir \[-HEX\] DIR \[...\]** **zzxorcopy \[-HEX\] FILE OUTFILE**

## DESCRIPTION

*zzcat* prints the given files to stdout, so you may want to redirect the output. The FILE can be a normal file or an inflated part of a zip archive (see OPTIONS).

*zzdir* prints the content table to stdout of the given DIR or zipfile.

*zzxorcat* prints the given files to stdout, so you may want to redirect the output. The FILE is an inflated part of a zip archive obfusctated with a xor value optionally given by the HEX option.

*zzxordir* prints the content table to stdout of the given DIR or zipfile. The DIR can br an inflated part of a zip archive obfusctated  with a xor value optionally given by the HEX option.

*zzxorcopy* copies data from FILE to OUTFILE adding simple  obfuscation by xor-ing each byte with the HEX value given.  Remember that copying data twice with the same xor-value will result in the original file data.

## OPTIONS

*zziplib-bin* tools accept the following options:

- **FILE**

  Input filename for reading or part (if supported by tool). Part is written as zipname/filename, e.g.: for accessing README inside of data.zip you'll specify data/README.

- **DIR**

  Disk directory, zipfile or inflated part of a zipfile.

- **-HEX**

  Hex number for xor-ing the zipfile contents. If not supplied all tools that use it take 0x55 as default value for xor-ing. **OUTFILE** Output file name for zzxorcopy.
