cli-tarHow can I compress multiple files using tar and gzip in parallel?

Using GNU Parallel, you can compress multiple files using tar and gzip in parallel. To do this, you need to create a tar archive of the files you want to compress and then pass the tar archive to gzip.

The following example code will compress the files file1.txt and file2.txt into files.tar.gz:

tar cvf files.tar file1.txt file2.txt
gzip files.tar

The output of the above code will be:

file1.txt
file2.txt

To compress these files in parallel, you can use the following command:

parallel gzip ::: files.tar

The output of the above command will be:

files.tar.gz

The code can be broken down as follows:

• parallel: This is the command for running commands in parallel.
• gzip: This is the command for compressing files using gzip.
• :::: This is the separator for the list of files to be compressed.
• files.tar: This is the tar archive containing the files to be compressed.
