I just trapped myself while hacking up a batch file.
Used to shell scripting I wanted to add a delay to the batch using "sleep".

Dough! Bad Idea! Bad command or filename. Smash your head here to continue {(x)}!

So I winded up my memories from stoneage. Wasn't there the choice command!?

Yeah, after some lurking around with the '/?' feature I had stuck it together:
choice /c 1 /d 1 /t 1 > nul

While

  • "/c 1" sets the choice values (1 is my value)

  • "/d 1" sets the default choice value (which is 1 from above)

  • "/t 1" sets the timeout to 1 second (or whatever is appropriate)

  • "> nul" means the same as ">/dev/null": send output to nirvana (notice there being only one 'l' however)


Of course this may be bothersome to type if you use it often, so a "batch function" may be better, especially when you need other batch tricks to get around DOS command limitations (lazy man's approach: create a second batch file for it).
