How to gzip multiple files into one gz file?
I have 100 files: cvd1.txt, cvd2.txt ... cvd100.txt
How to gzip 100 files into one .gz file, so that after I gunzip it, I should have cvd1.txt, cvd2.txt ... cvd100.txt separately?

if you have zip,
zip myzip.zip cvd*.txtDon't need to tar them first.
You want to tar your files together and gzip the resulting tar file.
tar cvzf cvd.tar.gz cvd*.txtTo untar the gzip'd tar file you would do:
tar xvzf cvd.tar.gz -C /path/to/parent/dirThis would extract your files under the /path/to/parent/dir directory
You'll want to use tar, like so:
tar -czvf file.tar.gz cvd*.txt
tar puts the files together, while gzip then performs the compression.
Quoth the gzip manpage:
If you wish to create a single archive file with multiple members so that members can later be extracted independently, use an archiver such as tar or zip. GNU tar supports the -z option to invoke gzip transparently. gzip is designed as a complement to tar, not as a replacement
gzip by itself does not know anything about file structure. To do what you want, you need to first put the files into some kind of container file (e.g. a tar structure, or similar) and then gzip that. tar has z and j (for bzip2) switches on GNU platforms to do this.
1You can do it using:
zip my_final_filename.zip my_first_file my_second_file ... my_last_file
unzip my_final_filename.gzor
tar cvzf my_final_filename.tar.gz my_first_file my_second_file ... my_last_file
tar -czvf my_final_filename.tar.gzUnfortunately gzip is not capable of doing that. In case of more information please look at comments.
To compress multiple files with different patterns, we could this :
tar -czvf deploy.tar.gz **/Alice*.yml **/Bob*.jsonthis will add all .yml files that starts with Alice from any sub-directory and add all .json files that starts with Bob from any sub-directory.
