[Batch Script Programming] Execute 2 commands in IF expression

You can execute 2 or more commands in one IF expression:

• You can use "&" to execute 2 or more command if a IF expression

@echo off

set A=12
set B=24

IF %A% EQU 12           echo "hawaii" & echo "los angles" & echo "tapiei"
The result is
"hawaii"
"los angles"
"tapiei"

• If you use set command right before "&", don't leave space. Or the space will become part of the value.



For example, following code will search \sources\boot.wim in each drive (from C to Z). If found, it will set variable RP the drive.

FOR %%d in (C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z) DO IF EXIST %%d:\sources\boot.wim set RP=%%d& GOTO END_SEARCH_RP

However, if you leave space befire "&", like this:

FOR %%d in (C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z) DO IF EXIST %%d:\sources\boot.wim set RP=%%d & GOTO END_SEARCH_RP

If "E" is the drive, the above code will set RP as "E ".
