Is there any software that can search and replace trough archives , zip, tar etc?
I fund PowerGrep 4 and was so happy to see that it can find the strings but replace fails with bad zip function , this one also fails
http://www.funduc.com/search_replace.htm
is there any way to do this.
I have over 200 archives to update and is just 1 string within 2-3 files per archive
The following Free Mac software will search and replace through zipped files without unzipping/rezipping:

I'm trying to implement a minimal version of .zip file generation following this spec: https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT
I don't actually need compression, I just need a way to string together a bunch of files into a single widely adopted archive format with the capability to stream in file data while streaming out the zip.
So far I'm partially successful, 7-zip and windows built in zip extractor can extract them just fine, winrar and macos built in zip extractor are giving me corrupted archive errors.
I can't for the life of me find the actual problem(s?) though, as far as I can tell the .zips are built 100% to the specification but the spec is a big wall of text and with swooping changes from one zip file version to the next along with legacy attributes taking on new functions it is tad confusing.
Does anyone know of an extraction tool that can give me more specific errors than just "archive is corrupt"?
Or perhaps a zip generation utility where I can pick and choose between all the different ways of building a zip file so I can go and compare the results byte by byte?
Does anyone know of an extraction tool that can give me more specific errors than just "archive is corrupt"?
The unzipada tool # Zip-Ada project will do exactly that
Testing archive ko.zip
raised ZIP.ARCHIVE_CORRUPTED : Bad (or no) end-of-central-directory
[C:\Ada\za\unzipada.exe]
Zip.Find_First_Offset at zip.adb:589
Unzip.Extract at unzip.adb:667
Unzipada at unzipada.adb:259
By browsing the code (like: zip.adb, line 589) you can narrow down the corrupt archive issues. For building the tool, download the sources and follow the readme.txt file. There are also pre-built binaries for Windows.
I though this would be simple, but i have been caught by the simplest of puzzles which i can't find the answer to anywhere,
I have some code which reads images and then OpenCV looks for differences.
I read files with the following command
vs = cv2.VideoCapture("/home/andrew/images/image_%6d.jpg")
and this work perfectly with images called image_000000.jpg image_000001.jpg
However i don't want to rename my images so i would like to read files called
MDAlarm_20180921-031140.jpg whcih contain the date then time.
What is the printf format for this ? as what ever I try it does not work i.e no files found or do the files need to start from 0 , so i need to append an index
starting at 000000?
Lastly once i have this working how can i tell which file is being processed ?
Many Thanks
Andrew
I'm researching a project on software defined networking discussed on knowledgedefinednetworking.org and they provide several datasets. Two of the three datasets are unzipping just fine (100K.csk.gz & train.csv.gz), but benchmark.csv.gz unzips into a new spreadsheet but still uses 3.3GB of memory. I'm using WinZip to unzip the files and they're all going into the same folder, but only benchmark is coming back empty. Is this a common issue or is there something potentially wrong with the download of the file that causes it to unzip empty?
"Is this a common issue" <-- Simple answer : Yes, it is a coomn issue.
"or is there something potentially wrong with the download of the file that causes it to unzip empty?" <-- the download went ok.. I tried to save it as excel. went ok. The files (file1 file2) is not blank.
Note : try to use 7zip as your file uncompressor.
Hope that solves... (:
I could not believe this: it seems that the zip specification does not allow two different files with the same file name going into one zip file.
In my case I use an external file to specify all the files I wanna zip.
This could look like this:
../Website1/favicon.ico
../Website2/favicon.ico
and there we are, that's not possible, despite keeping the directory structure. You would expect the name to be <../Website1/favicon.ico> rather than but that does not seem to be the case, I get:
"Invalid ZIP request (cannot repeat names in Zip file)"
with WinZip. I tried the same with 7Zip - same result.
Strangely googling did not show many hits that really fit but those I found seem to confirm my findings. That's hard to believe since this limitation is very severe. I actually struggle to understand why this did not hit me a couple of decades earlier.
Am I overlooking something very basic here?
To be precise:
Adding these two files:
C:\Temp\Website1\FavIcon
C:\Temp\Website2\FavIcon
results in a single file; the last Add wins...
This however:
Website1\FavIcon
Website2\FavIcon
results in a zip file that contains both files.
I'm trying to store whole the output of my build, this includes some empty folders. These aren't included by the artefact mechanism in teamcity:
What doesn't work:
OAR\=> OAR.zip
OAR->OAR.zip
OAR
Inside of OAR i have a folder structure that needs to be stored. I know i could put a placeholder file in each but that is not the answer i'm after. Otherwise ill have to zip it myself?
Unfortunately TeamCity, by design, searches for files and uploads them as artifacts which means that empty folders are never included. Given the open and very old issue in the TeamCity tracker I doubt they are going to fix it any time soon.
I would recommend zipping the folder yourself, that is the approach we have taken. How you implement that depends on the build technology you are using. For example, if you are building using Nant you could add the zip task to your build, there are similar options for MSBuild and Ant.
If you don't want to rely on the build performing the zip I would recommend installing 7zip on your build agents and using the command line to perform the zip. Just remember if you want 7zip to include empty directories use * as the wildcard rather than *. * like so:
7z a -r OAR.zip *
Technically you could use powershell to do the zipping, which would be better than having to install something on your agents. I haven't tried this option myself.
