Mengecek dan Menguji MD5 File

Sebagai contoh kita akan mendownload ISO ArchLinux

wget http://suro.ubaya.ac.id/archlinux/iso/2014.02.01/archlinux-2014.02.01-dual.iso

setelah selesai di download, download nilai MD5-nya

wget http://suro.ubaya.ac.id/archlinux/iso/2014.02.01/md5sums.txt

lalu jalankan

md5sum -c md5sums.txt

hasilnya

archlinux-2014.02.01-dual.iso: OK
md5sum: archlinux-bootstrap-2014.02.01-i686.tar.gz: No such file or directory
archlinux-bootstrap-2014.02.01-i686.tar.gz: FAILED open or read
md5sum: archlinux-bootstrap-2014.02.01-x86_64.tar.gz: No such file or directory
archlinux-bootstrap-2014.02.01-x86_64.tar.gz: FAILED open or read
md5sum: WARNING: 2 listed files could not be read

file archlinux-2014.02.01-dual.iso sesuai dengan aslinya, jadi silahkan di lanjut instalasinya :). Bila md5 tidak sesuai yang muncul

archlinux-2014.02.01-dual.iso: FAILED
md5sum: archlinux-bootstrap-2014.02.01-i686.tar.gz: No such file or directory
archlinux-bootstrap-2014.02.01-i686.tar.gz: FAILED open or read

archlinux-bootstrap-2014.02.01-x86_64.tar.gz: FAILED open or read
md5sum: WARNING: 2 listed files could not be read

coba download ulang, karena bila di lanjutkan ke proses instalasi bisa mengalami error.
