hashs

allows to calculate several hash functions simultaneously

installation

make the bash hashs script executable and move it to one of your $PATH folders :

$ chmod +x ./hashs

$ echo $PATH
/home/user/.local/bin:/bin:/usr/bin:/usr/local/bin

$ # for personal use
$ mv ./hashs /home/user/.local/bin

$ # for system use
$ sudo mv ./hashs /usr/local/bin/

hashs uses xxHash non-cryptographic hash function : you can install it if you want to use it or delete the corresponding line of the script if you don't.

usage

hashs can process one or more files :

$ hashs /tmp/zfs.disk 
/tmp/zfs.disk
size   : 3276800
