Top Forums Shell Programming and Scripting Bizzare behavior on redirect of stdout Post 302945353 by edstevens on Thursday 28th of May 2015 01:30:25 PM

Hmm. Another case of getting so close to the code that one doesn't see it any more. In this case, the deleting of the log file within the script was a vestige of the larger script from which this test piece came. And that script was doing its own logging, rather than redirecting the output as a whole, as in my test. One thing I still don't understand though. Given that I was redirecting stdout of the script as a whole (myscript > myscript.log) even with a command inside the script deleting that same file, would not the next command that generates stdout in the script re-create the specified file?

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. AUTHORS
