Bash installer: Permission denied

[abe-101]

When I run the bash installer on my fedora machine I get this error:

mv: cannot create regular file '/usr/local/bin/railway': Permission denied

running the cmd with sudo doesn't help

my guess is this is the problomatic line https://github.com/railwayapp/cli/blob/22b8aafc33cf713a1c0f84c5408112f6c14fff4d/install.sh#L150
