FOR /F – 做在一個檔案裡的指令. FOR /F ["options"] %variable in (file-set) do command [command-parameters] FOR /F ["options"] %variable in ("string") do command [command-parameters] FOR /F ["options"] %variable in ('comma, 最近從Visual Studio 2010 的建置部署套件功能自動產生的網站安裝批次檔中學到一個批次檔的使用技巧，他可以透過批次檔直接讀取機碼(Registry)的資訊並擷取出執行檔所在路徑，這樣一來就不用將執行檔所在的路徑寫死在批次檔裡，是非常彈性的一種方法，藉此也剛好把批次檔的FOR 語法的使用方式給釐清一 ...,Take a set of data; Make a FOR Parameter %%G equal to some part of that data; Perform a command (optionally using the parameter as part of the command). Repeat for each item of data. If you are using the FOR command at the command line rather than in a ba, for /l is your friend: for /l %x in (1, 1, 100) do echo %x. Starts at 1, steps by one, and finishes at 100. Use two % s if it's in a batch file for /l %%x in (1, 1, 100) do echo %%x. (which is one of the things I really really hate about windows scri, command can be any internal or external command, batch file or even - in OS/2 and NT - a list of commands. parameters contains the command line parameters for command. In this example, command will be executed once for every element in list, using parame, Your problem is that the variable get replaced when the batch processor reads the for command, before it is executed. Try this: SET temp=Hello, world! CALL yourbatchfile.bat. And you'll see Hello printed 5 times. The solution is delayed expansion; yo, Command line usage: for /f %f in (`dir /b c:-`) do echo %f. Batch file usage: for /f %%f in (`dir /b c:-`) do echo %%f. Update: if the directory contains files with space in the names, you need to change the delimiter the for /f command is using. for exa, You're using the same FOR variable ( %%1 ) for the two loops. Since they are nested, you should use different variables. The first for loop claims 10 variables (since you asked for 10 tokens), so for the second one you'll need different variables, It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing. In other words, %count% is replaced with its , You can do it similarly like this: ECHO Start of Loop FOR /L %i IN (1,1,5) DO ( ECHO %i ). The 1,1,5 is decoded as: (start,step,end). Also note, if you are embedding this in a batch file, you will need to use the double percent sign (%%) to prefix your v
