How can I find the version of the Fedora I use?

linux fedora

cat /etc/issue

Or cat /etc/fedora-release as suggested by @Bruce ONeel

linux fedora

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release Fedora release 7 (Moonshine)

linux fedora

You can execute something like:

$ source /etc/os-release$ echo $IDfedora$ echo $VERSION_ID17$ echo $VERSION17 (Beefy Miracle)
