CRC32

CRC32 checksums are used to verify if a file has been accidentally damaged (for example, an interrupted download).

To check the CRC32 checksum of a file you can use the following command:

crc32 /path/to/file

If this command is not available on your system and if you have a Debian-bases system, you can install it with:

sudo apt-get install libarchive-zip-perl
