ELSE

Else is an option for the IF command

IF [NOT] EXIST filename (command) ELSE (command)

When combining an ELSE statement with parenthesis, always put the parenthesis on the same line as ELSE.
This is because CMD does a rather primitive one-line-at-a-time parsing of the command.

so

… ) ELSE ( …

will work, but

… )
ELSE ( …

will fail.

If you follow this rule, you can nest mutiple IF commands to in effect provide an ELSEIF.
Add parenthesis where needed:

… ) ELSE ( IF condition ( action_if_True ) )

… ) ELSE IF condition ( action_if_True )

… ) ELSE IF condition action_if_True

Examples

IF EXIST sample.txt (Del File.txt) ELSE (copy File1.txt File2.txt)


IF %1==dev (Echo Found Dev
   ) Else ( If %1==tst (
                       Echo found Tst
                       ) ELSE ( If %1==trn
                               Echo found Train
                              )
           )
