[TriLUG] Single line scripts

[Grawburg via TriLUG]

I have long commands I enter in a terminal, such as starting connecting to a Raspberry Pi located several floors away with ssh, or
setting up a connection to my NAS (rather than having a line in /etc/fstab).
I can simply have a text file saved and do a copy and paste into terminal each time I need it, but I'd like to turn it into a what I
would have called a .bat file decades ago.  
Is this something I should learn to to do in bash? I don't need multiple lines, there is no extra coding, just a single line.


Thanks,
Brian Grawburg
