macOS Filter a command output to be used as an alias

[gpchess2k]

Hello! Simple stupid question..... I cant seem to figure out for the life of me. I want to use the output of a command but trim it before using it as an alias.

scutil --get HostName

If output is: macbookpro123.internet.com

I would like to use this output as an alias without '.internet.com'.

Try this:

scutil --get HostName | sed 's/\..*//'

It will return the string to the left of the first .
