I have a folder, TestFolder, that contains several .gz files. Each .gz file is a folder containing several sub-directories, with the deepest level of each .gz file containing 5 text files. For example, extracting one of the .gz files ultimately has 5 files at the deepest level of the directory, like:
Users/me/Desktop/TestFolderParent/TestFolder/folder1/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/TextFile1.txt
Users/me/Desktop/TestFolderParent/TestFolder/folder1/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/TextFile2.txt
Users/me/Desktop/TestFolderParent/TestFolder/folder1/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/TextFile3.txt
Users/me/Desktop/TestFolderParent/TestFolder/folder1/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/TextFile4.txt
Users/me/Desktop/TestFolderParent/TestFolder/folder1/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/TextFile5.txt
when I run gunzip -r /Users/myuser/Desktop/TestFolderParent/TestFolder in terminal, it extracts all of the .gz files, each as a single text file containing all 5 constituent text files concatenated together. Is there any way to instead run a command to extract each .gz file and return each of the 5 constituent text files as a separate file?
.gz files themselves do not and cannot contain "several sub-directories". The gzip format compresses a single file, and that's it. gunzip will extract exactly one file from one .gz file.
That single file can itself be an uncompressed archive of files. That is often done using the tar archiver, so you end up with a .tar.gz file. Is that what you have? Then you need to use tar, not gunzip to extract the files.

My files name is <09/12/2020>_master. How would I be able to add this file to a .gz archive and then remove the original file?
GZip isn't an archive format, it's a compression format. A .gz file can only contain one compressed file; if you need to put more than one file in at a time, you'll need to pair it with an archive format (such as tar).
zip.UnzipMatching("qa_output","*.xml",true)
With this syntax I can unzip every Xml in every directory from my zip file and create the same directory structure.
But how can I unzip only the xml in the root directory?
I cannot understand how to write the filter.
I tried with "/*.xml" but nothing is extracted.
If I write "*/*.xml" I only extract xml files from subdirectory (and I skip the xml in the root directory!).
Can anyone help me?
example of a zip files content:
a1.xml
b1.xml
c1.xml
dir1\a2.xml
dir1\c2.xml
dir2\dir3\c3.xml
with unzipmatching("qa_output","*.xml", true) I extract all this files with the original directory structure, but I want to extract only a1.xml, b1.xml and c1.xml.
Is there a way to write filter to achieve this result, or a different command, or a different approach?
I think what you want is to call UnzipMatchingInto: All files (matching the pattern) in the Zip are unzipped into the specfied dirPath regardless of the directory path information contained in the Zip. This has the effect of collapsing all files into a single directory. If several files in the Zip have the same name, the files unzipped last will overwrite the files already unzipped.
I have a tar.gz file which includes 2 tar files and each tar file includes several folders and subfolders that include my required files.
I want to extract the final files from those subfolders in a directory.
I know I can use something like tar -xzvf but finally, it gives me all the folders and subfolders and the files I needed in those subfolders.
Example file:
file.tar.gz: this file contains 1.tar and 2.tar. 1.tar contains folder1, folder2, ..., folder100. and 2.tar contains foldera, folderb, ..., folderz. My text files are in these subfolders.
I want to extract all of my text files in a user-defined directory without extracting subfolders. my_dir/*.txt
Any help would be much appreciated.
Thank you.
I'm working on creating bash script to read a CSV file (comma delineated). The file contains parts of names for files in another directory. I then need to take these names and use them to search the directory and copy the correct files to a new folder.
I am able to read the csv file. However, csv file only contains part of the file names so I need to use wildcards to search the directory for the files. I have been unable to get the wildcards to work within the directory.
CSV File Format (in notepad):
12
13
14
15
Example file names in target directory:
IXI12_asfds.nii
IXI13_asdscds.nii
IXI14_aswe32fds.nii
IXI15_asf432ds.nii
The prefix to all of the files is the same: IXI. The csv file contains the unique numbers for each target file which appear right after the prefix. The middle portion of the filenames are unique to each file.
#!/bin/bash
# CSV file with comma delineated numbers.
# CSV file only contains part of the file name. Need to add IXI to the
beginning, and search with a wildcard at the end.
input="CSV_file.csv"
while IFS=',' read -r file_name1
do
name=(IXI$file_name1)
cp $name*.nii /newfolder
done < "$input"
The error I keep getting is saying that no folder with the appropriate name is able to be identified.
I have a number of compressed archives with the extension .tar.xz. I am advised that, when decompressed, the total size required is around 2TB.
Within the archives are a number of images that I am solely after.
Is there a method to solely extract files for example with the extensions .jpeg, .jpeg and .gif from the compressed archives without having to extract every file?
Thanks
It's trivial to just extract one of the file types; for example:
tar -xjf archive.tar.xz '*.jpeg'
will extract all files with the .jpeg extension. It's important to quote the *, as otherwise the shell would attempt to expand it, and would only try to match only the files that were found (or fail because there were no files with that name).
You can similarly use other patterns like '*.gif', or both together:
tar -xjf archive.tar.xz '*.jpeg' '*.gif'
Because you tag that you're using OSX, I'll skip the need to use the --wildcards option, which is needed when trying to extract only those files under linux.
