Using command output in DOS

I would like to run a command in DOS, which uses the output of another command as its part, something that single back-quote (``) allows to do on UNIX or Linux.

For example, if myCommand returns a list of files, I would like to execute in DOS some analog of the UNIX command

grep `myCommand`

How would one do that in DOS? Thank you in advance for your 开发者_开发知识库help.

You can pipe two commands:

command1 | command2

But there aren't a whole lot of commands whos input/ouput plays well with each other. You'd probably be best off using a for loop. The basic syntax is:

for /f %A in ('command1') do command2 %A

Unless you try the for %%i in ... syntax, I do not see a hope in DOS. DOS is not Unix.

Another solution is to build a new batch using the for loop (with @ and echo) and start the new batch at the end.

You may need to do this recursively.
