Such as I want to use the batch implement such a demand, the current folder obj files are assigned to a variable, such as D: \ work under a a.o bj, b.o bj and c.o bj etc. Multiple files, now the traverse D: \ work this folder, all the OBJS obj file path are given, finally the value of the output OBJS is OBJS=D: \ work \ a.o bj D: \ work \ b.o bj D: \ work \ c.o bj

Code is roughly as follows:

 
The set OBJS=
For/r./% % a in (*. Obj) do (
The set OBJS "OBJS=% % % % a" 
) 
Echo OBJS % % 

But the code does not achieve this effect,

Warrior, what you say to a single variable assigned a value, the main problem is how multiple values pieced together,

Find the right way, the code is as follows:

 
@ echo off 
SETLOCAL EnableDelayedExpansion 
The set OBJS=
For/r./% % a in (*. Obj) do (
Set "OBJS=! OBJS! % % a "
) 
Echo OBJS % %

This patchwork is not string,

CodePudding user response:

OBJS=D: \ work \ a.o bj D: \ work \ b.o bj D: \ work \ c.o bj
This is not a a.o bj, b.o bj, c.o bj three files of the full path name string literals are concatenated with Spaces up results?
