Initialize a test variable containing a delimitted list of acceptable values, and then use search and replace to test if your variable is within the list.
This is very fast and uses minimal code for an arbitrarily long list. If doing the test within a block where delayed expansion is needed to access current value of VAR then for The code has begun to look a bit "ugly", but I think it is the best performing reliable method for testing if VAR is any one of an arbitrary number of case-insensitive options.
Finally there is a simpler version that I think is slightly slower because it must perform one IF for each value. One other limitation with this solution is it does not provide the option for an ELSE clause unless you add an indicator variable.Because the commands that are contained in the heartoftexashop.com are executed by a master shell one-by-one..
So the master shell executes the sudo, waits for it to exit, before it proceeds with the other commands (ls and cd).And the sudo does not exit (at least not on its own)..

When running ad-hoc commands, use your best judgement.
