It's not clear how you are invoking the shell from C, or vice versa. If you want to capture the output from a shell command in C, the customary way to do that is with popen()

zziplib-bin

ZZIPLIB-BIN(1)						      General Commands Manual						    ZZIPLIB-BIN(1)

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.
