The slist.sh does not do an exact match to user input when obtaining the host to ssh into

[Salihan04]

The above image is the error I got.

I then modified the script to echo the $host and saw that when obtaining which host to ssh into, the script does not do an exact matching to user's input.

Solution:
The solution is simple, replace ^${cs} with ^${cs} . Not the whitespace at the end.
