pigz – Can Be Used to Decompress Files, an Upgraded Version of Gzip’s Parallel Implementation

Pigz is a command-line utility that can be used to compress and decompress files. It is an upgraded version of gzip’s parallel implementation, which allows for faster compression and decompression of large files.

To decompress a file using pigz, you can use the following command:

pigz -d file.gz

This will decompress the file.gz file and create a new file without the .gz extension.

Pigz can also be used to decompress multiple files at once using the following command:

pigz -d *.gz

This will decompress all files with the .gz extension in the current directory.


The following table lists all available options for the pigz command:

Option Description
-p Specifies the number of processors to use for compression/decompression. The default is to use all available processors.
-k Keeps the source file after compression/decompression.
-c Writes the output to the standard output instead of a file.
-f Forces compression/decompression even if the output file already exists.

Troubleshooting Tips

If you encounter issues with pigz, you can try the following troubleshooting tips:

  • Make sure you have the latest version of pigz installed.
  • Check the spelling and syntax of your command.
  • Ensure that you have the necessary permissions to read and write files.
