I have a batch file that runs each day and downloads about 20 .zip files from a network share to a server which then extracts them.. before continuing with other bits and bobs
the copying is carried out by ROBOCOPY, and the extraction done by 7zip
this was all working fine til yesterday when i realised my process was falling over every time. Turns out one of the .zip files was corrupt and when it tried to extract the batch file just bombs out
7zip has a file integrity check option but i cant for life of me figure out how to get the result of this check into something like an IF THEN ELSE execute the extract part
options i have considered:
1. only copy correct files with robocopy (cant work out how to check integrity, or even if its possible)
2. do a crc on the files - not really useful as i dont know what the results should be
3. use the 7zip t flag in some manner - 7z.exe t filename.zip and generate an ERRORLEVEL in the batch... bit lost on this one??????
5. batch file try-catch 'hack' - ok i was desperate at this point... :)
can anyone figure out a clever method of making this work? i will be eternally grateful because its starting to really **** me off... :p
perhaps i could run a check, output the successful results to a file and then only extract the filenames that are contained in that file??
Operation Warp Speed Vaccine Summit - December 8, 2020
Donald Trump: Thank you very much. Appreciate it very much.
I’m honored to welcome doctors, scientists, industry executives, and state and local leaders to our historic Operation Warp Speed Vaccine Summit. It’s been some journey for all of us. It’s been an incredible success.
We’re grateful to be joined by Vice President Mike Pence, who has done an absolutely incredible job on the Coronavirus Task Force. Mike, thank you. Stand up, Mike. (Applause.) Great job.
We’re here to discuss a monumental national achievement. From the instant the coronavirus invaded our shores, we raced into action to develop a safe and effective vaccine at breakneck speed. It would normally take five years, six years, seven years, or even more. In order to achieve this goal, we harnessed the full power of government, the genius of American scientists, and the might of American industry to save millions and millions of lives all over the world. We’re just days away from authorization from the FDA, and we’re pushing them hard, at which point we will immediately begin mass distribution.
Before Operation Warp Speed, the typical timeframe for development and approval, as you know, could be infinity. And we were very, very happy that we were able to get things done at a level that nobody has ever seen before. The gold standard vaccine has been done in less than nine months.
And now this:
Meghan McCain: If you regret taking the shot, there's hope. Buy this "Vaccine Detox"
