I have a .bin file that will comprise of 3 files
1. tar.gz file
2. .zip file
3. install.sh file
For now the install.sh file is empty. I am trying to write a shell script that should be able to extract the .zip file and copy the tar.gz file to a specific location when the *.bin file is executed on an Ubuntu machine. There is a Jenkins job that will pull in these 3 files to create the *.bin file
My Question is how do I access the tar.gz and .zip file from my shell script ?
There are two general tricks that I'm aware of for this sort of thing.
The first is to use a file format that will ignore invalid data and find the correct file contents automatically (I believe zip is one such format/tool).
When this is the case you just run the tool on the packed/concatenated file and let the tool do its job.
For formats and tools where that doesn't work and/or isn't possible the general trick is to embed markers in the concatenated file such that the original script ignores the data but can operate on itself to "extract" the embedded data so the other tool can operate on the extracted contents.

Basically I have .bz2.gz.bz2 file which on extraction gives a .bz2.gz file and on again extraction gives .bz2 file. In this .bz2 file, is my txt file which I want to search on using grep command. I have searched for this but I got bzgrep command which will only search in bz2 file and not the corresponding .gz.bz2 file and give me no results.
Is there a command in unix system which will recursively search in a zipped archive for zipped archive and return results only when it finds the txt file inside it?
P.S: the txt file may be deep in the archive to level 10 max. I want the command to recursively find the txt file and search for the required string. And there will be no other than an archive inside the archive until the txt file level.
I'm not sure I fully understand but maybe this will help:
for i in /path/to/each/*.tar.bz2; do
tar -xvjf "$i" -C /path/to/save/in
rm $i
done
extract all `tar.bz2` and save them in directory then remove the `.bz2`
Thnx for sharing your question.
There are a couple of strange things with it though:
It makes no sense to have a .bz2.gz.bz2 file, so have you created this file yourself? If so, I'd advise you to reconsider doing so in that manner.
Also, you mention there is a .bz2 that would apparently contain different archives, but a .bz2 can only contain one single file by design. So if it contains archives it is probably a .tar.bz2 file in which the tar-file holds the actual archives.
In answer to your question, why can't you write a simple shell script that will unpack your .bz2.gz.bz2 into a .bz2.gz and then into a .bz2 file and then execute your bzgrep command on that file?
I do not understand where it is exactly that you seem to get stuck..
I am working on a batch file and trying to write the correct windows commands.
1) Command-line from Windows
2) Use commands to scan the zip file so that it will look inside of the zip file for a specific string in the file within the zip file.
3) If the scan finds that specific string in the file that is within the zip file then move that zip file to another specified directory.
Is it possible using dos commands within a batch file?
I want to learn more on this. Anyone have any guidance or suggestions?
Compressing a folder into a .zip file is a common way to treat a folder as file, for example, uploading a folder. Is there a faster way to "pack" the contents of a folder into a file (without taking the time to compress)?
You should use a tarfile. In unix or mac, its the tar command. On Windows there is a tool called 7-zip.
You can see more details here.
I have zip file containing my installation files. I'm extracting this zip and copying these files into installation directory with the script shown below:
ZipDLL::extractall "$OUTDIR\demo.zip" "C:\myapp\demo\"
if I remove zip file from $OUTDIR than installer is not able to find zip file as expected. What I want to do is embedding this zip or its extracted folders into exe itself. I added
File -r "$OUTDIR/demo"
but this script didn't worked as well.
When you use the ZipDll plugin, you are referring to the file you want to process (demo.zip) by using its place at run time: along the installer.exe.
When you use the File statement to embed some files into the produced installer, you need to refer to the files by using their place at compile time.
Replace the $OUTDIR in the File statement by the path relative to the .nsi script.
BTW, you should take the habit to check at the compilation log, NSIS probably tells you about that kind of problem when paths are incorrect at compile-time.
I have a script set up to rotate some log files in windows, and as part of the process I'd like it to automatically compress the rotated file. To do this I use the command
compress source.file destination.file.zip
However, if I try to open the file, I get the message "The Compressed (zipped) Folder is invalid or corrupted"
I've tried compress with -Z, and I get the same message. What am I doing wrong?
compress output is not ZIP file format compatible, it uses the LZW algorithm.
The only way to "open" a compressed file is with uncompress or gunzip.
Windows ports of common Unix commands, including compress and gzip/gunzip available here.
EDIT: To produce ZIP files from the command line in Windows, you can use something like 7-Zip, which includes a command line application (7z.exe). The Unix commands linked above also include zip.exe for manipulating ZIP files from the command line.
