This makes standard use of shellcheck work without needing to provide extra configuration anywhere. Also remove use of inline 'shellcheck disable' calls that are already defined in the .shellcheckrc and don't need to be set inline.

# A script to bootstrap dokku.
|
|
# It expects to be run on Ubuntu 20.04/22.04 via 'sudo`
|
|
# If installing a tag higher than 0.3.13, it may install dokku via a package (so long as the package is higher than 0.3.13)
|
|
# It checks out the dokku source code from GitHub into ~/dokku and then runs 'make install' from dokku source.
|
|
|
|
# We wrap this whole script in functions, so that we won't execute
|
|
# until the entire script is downloaded.
|
|
# That's good because it prevents our output overlapping with wget's.
|
|
# It also means that we can't run a partially downloaded script.
