To check the integrity of your downloaded file, it will be necessary to first open the downloaded checksum file using a text editor such as ''Gedit''. Depending on whether you intend to use sha1 or sha256, ensure that you have downloaded and opened the appropriate checksum file ~~(i.e.~~ ending in ~~-sha1~~.~~sum~~ or ~~-sha256~~.~~sum,~~ respectively) as they will contain different codes. Once the checksum file has been opened - and the code is visible - open up your terminal and change to the directory where your downloaded ISO is stored. For example, if your ISO file is located in the default ''Downloads'' folder, you would enter the following command:

To check the integrity of your downloaded file, it will be necessary to first open the downloaded checksum file using a text editor such as ''Gedit''.

Once the checksum file has been opened and the code is visible, open up your terminal and change to the directory where your downloaded ISO is stored. For example, if your ISO file is located in the default ''Downloads'' folder, you would enter the following command:

cd Downloads

As illustrated, in this instance both codes match, thus confirming that the downloaded ISO file is ~~completely fine~~. The following command would use sha1 to undertake exactly the same task:

As illustrated, in this instance both codes match, thus confirming that the downloaded ISO file is correct. The following command would use sha1 to undertake exactly the same task:

sha1sum manjaro-xfce-0.8.1-x86_64.iso

~~Where~~ satisifed that both codes match, then it is safe to proceed to either burning the ISO to your chosen installation, or using it immediately in Virtualbox. ~~Otherwise~~, it will be necessary to delete the ISO image and download it again.

When satisifed that both codes match, then it is safe to proceed to either burning the ISO to your chosen installation media, or using it immediately in Virtualbox. If not, it will be necessary to delete the ISO image and download it again.
