7Zip Commandline - Output Error Logging Syntax?

[Kevin Finnegan]

Hi all,

Long time lurker and now forum poster! I'm writing a relatively simple backup script for my firm that automates the copy, compression and organization of Leaver's data on one of our secured NAS systems. I personally found the best method to do this so far was to use 7zG.exe (GUI version of 7Zip which can use command-line too) and it functions quite well!

I would like to retrieve more info on whether any warnings or errors happen in 7Zip during the backup, but I can't quite get my head around the syntax and switches for reading out, it seems any adjustment I make to the RunWait call's string seems to break the backup or give unexpected repercussions! Hopefully its something silly I'm doing as I don't code very often.

Here is the working version:

; Compress the directories one by one in the zip using the listfile....
Local $iPID = RunWait(@ScriptDir & "\bin\7zG.exe a -mx" & $compressionQuality & " -v" & $compressSplitFileSize & " -wc:\temp " _
         & $backupToLocation & "\" & $userDirectory & ".7z @bin\listfile.txt -x@bin\excludefile.txt", "", @SW_SHOWDEFAULT, $STDOUT_CHILD)

Ultimately I would love to switch entirely to 7za.exe (standalone) so that I can read the progress percentage, current file being uploaded and any warnings or errors could be processed and output to the AutoIT script's GUI I've created rather than jumping in and out of two applications per se.

What do you get when you set the log level using

-bb[0-3]

as described here?

Cheers @water with your help and a small change to the use of double quotation marks, that did the trick!

; Compress the directories one by one in the zip using the listfile....
Local $iPID = Run(@ScriptDir & '\bin\7z.exe a -mx' & $compressionQuality & ' -v' & $compressSplitFileSize & ' -wc:\temp "' _
         & $backupToLocation & '\' & $userDirectory & '.7z" @bin\listfile.txt -x@bin\excludefile.txt -bb3', "", @SW_SHOWDEFAULT, $STDIO_INHERIT_PARENT)

I switched to single quotation marks after I realized when reading through the 7Zip command-line guide, that double quotes should be used around the folder locations, especially if they have any whitespace. The next step is to poll what's logged to the console and push it to the GUI.
