I tend to wrap my batch files in a setlocal / endlocal pair to prevent variables I use in the script from "leaking" out into the parent shell's environment.įinally, I'll echo what says: If you can avoid using cmd.exe then, by all means, avoid it. Observe: offįor /L %%g in (%start%, %interval%, %end%) do call :_d %%gįor this particular case it's more code, to be sure, but for less trivial batch files I think it's a "win".Īs an aside: You have no setlocal / endlocal in there, so the values for first and last will persist across executions, assuming you keep running them in the same shell, and give you different results the second time you run your code.

Example 1: Count From 1 To N in a Batch File Using For Loop. It allows triggering the execution of commands found in this file.

#FOR LOOP IN BATCH SCRIPT EXAMPLE SERIES#

The batch file contains a series of DOS (Disk Operating System) instructions.

#FOR LOOP IN BATCH SCRIPT EXAMPLE HOW TO#

Inside the call variable expansion happens "normally". I n this tutorial, we are going to see how to increment counter using For Loop. I find the delayed expansion a bit ugly and confusing for longer subroutines, so I'll tend to have a lone call as the "body" of a for loop. I hope one of the (last two) examples suits the requirements for your script.Is right on. Here the outer loop finishes its execution without being affected by the broken inner one.

#FOR LOOP IN BATCH SCRIPT EXAMPLE CODE#

To not break the outer loop, a sub-routine holding the inner loop and being called ( call) from the outer one is required to hide the code block context of the outer loop from the goto break-up method: off The script below breaks the inner loop when a certain condition is net. You will notice that the inner loop finishes execution before the outer one is broken. The result of the check is transferred to the outer loop using a variable FLAG: off The batch file here breaks the outer loop when the a certain condition in the inner loop is met. The following code snippet breaks both loops upon a certain condition is met: offĪs you can see, execution of the loop construct is interrupted immediately at a certain point. You can easily reproduce that when you increase the end value 5 to a huge number like 1000000.īut now let us concentrate on nested loops (two in each example): Note that the loop actually completes the counting internally, but no more commands are executed. The example below breaks the loop depending on its loop counter value: offĪlthough the loop is specified to count up to 5, the output is: 0 So let me elaborate on that.īreaking a single for loop is simple: put goto :STOP into the loop and the label :STOP in the line following the loop structure. I do not exactly understand what you are trying to accomplish, but I do understand how to break out of nested for loops (or any other nested parenthesised blocks of code).

Rwinsta %%i /server:%%l & echo Disconnected sessions terminated (Optimizations welcomed) offĮcho This will look for a specific userID AND kill disconnected sessions on all servers!įor %%a in (q:scripts1commoncitrixlists*.txt) do (Įcho Looking for %username% and killing disconnected sessions on %%lįor /f "tokens=3" %%b in ('qwinsta *tcp /server:%%l ^| find /i "%userid%"') do echo %%b | rwinsta %%b /server:%%l & echo SESSION FOR %userid% KILLED ON %%lįor /f "tokens=2" %%i IN ('qwinsta /server:%%l ^| find /i "disc"') DO ( Unlike a lot of other programming and scripting languages, Batch Script doesnt have the concept of a while loop, however, similar behaviour can be produced by using an ‘if’ statement, discussed in the previous section, along with a. Here's what I have so far, and it works like a charm. Batch Script has one type of loop called a for loop, which can be used in a number of different ways.

If the session is found in farmlist2.txt, I want to FINISH searching in that list, but don't continue to farmlist3.txt. I want to cycle through the lists until I find the users session, and then stop when that list is finished (not stop when the session is cleared, they may have multiple sessions in the farm). Goal: Search for sessions on a server matching a specific user ID, and also kill any disconnected sessions found Next, adding the pause statement before the goto line prompts the user to press any key before looping the batch file. In the following example, the list of values (Mon, Tue, Wed, Thu and Fri) are directly given after the keyword in in the bash for loop. Static values for the list after in keyword. The following 12 examples shows how to bash for loops in different ways. For example, the following 3x10. This is usually used to increment a loop counter. The general syntax for a while loop is as follows: while condition do COMMANDS done. echo off cls :start echo Example of a loop pause goto start. The while loop is another popular and intuitive loop you can use in bash scripts. I know breaking out of a nested loop is fairly easy, however, I'm not sure how to do it when I'm working with multiple lists of servers. In this first example, the computer prints 'Example of a loop' over and over until you terminate the file.
