Remove Original File After Gzip Compression on Ubuntu

When compressing files in Ubuntu using gzip, managing disk space efficiently is often a priority. This article provides a quick overview of how the gzip utility handles original files by default and confirms the specific command usage required to ensure the source file is removed immediately after compression without extra steps.

Default Behavior of Gzip

By default, the gzip command on Ubuntu automatically removes the original file after successful compression. You do not need to add a specific flag to delete the source file because this is the standard behavior of the utility. When you run the compression command, the original file is replaced by the new compressed version with a .gz extension.

The Command

To compress a file and remove the original, simply use the following command in your terminal:

gzip filename

Replace filename with the actual name of the file you wish to compress. For example, running gzip document.txt will create document.txt.gz and delete document.txt.

Keeping the Original File

If you ever need to keep the original file instead of removing it, you must use the -k flag. This is the only scenario where the original file remains after compression. The command for keeping the original file is:

gzip -k filename

If you have already compressed a file using the -k flag and wish to remove the original manually, you can use the standard remove command:

rm filename

Summary

For standard compression tasks where disk space is a concern, the basic gzip command is sufficient to remove the original file. No additional options are required to enable this deletion feature.
