Read a from a text file, set as a variable

[Rawns]

Possibly a simple task but I can't seem to find out how to do this! Two files:

 

Drive.txt

Command.bat

 

Drive.txt simply contains "D:"

 

How can I get the batch file to read "D:" in the drive.txt file and set it as a variable?

The for command is your friend there.

A bit more detail - you just want the single line:

 

for /f %%i in (drive.txt) do set drive=%%i

Thanks guys! One last search in Google pulled this up:

 

set /p Drive=
 

Seems to work a treat.

This is a good reference for commands like FOR or SET

set /p Drive=

That will work as long as you don't have a requirement for processing more than one line.

Nope, it will only ever be one line, but I can see this being useful so will explore the for command a bit more too.

Didn't know about set /p and reading from a file this may come in useful!
