How can I loop or start a batch file over after it has
completed?
Question:
How can I loop or start a batch file over after it has completed?
Answer:
Using the goto command within a batch easily allows a user to
loop or restart a batch file after it has been completed below are
some examples of how this command can be used. This page was created
with the easiest but not necessarily recommended solution first to
the most difficult solution but recommended method last.
@echo off
cls
:start
echo This is a loop
goto start |
In this first example, the computer will print "This is a loop"
over and over until you terminate the file. To cancel this example
press: CTRL + C.
@echo off
cls
:start
echo This is a loop
pause
goto start |
Next, adding the pause statement before the goto line will
prompt the user to press any key before looping the batch file. This
is helpful and recommended to help prevent the computer from
utilizing all or most of its resources in having to continuously
rerun the loop and will allow the user to rerun the batch when
they're ready.
@echo off
cls
:start
echo This is a loop
set choice=
set /p choice="Do you wish to restart? Press 'y' and enter
for Yes: "
if not '%choice%'=='' set choice=%choice:~0,1%
if '%choice%'=='y' goto start |
Finally, in this last example and most recommend method the user
would be prompted if they wish to rerun the batch file. Pressing "y"
would use the goto command and go back to start and rerun the batch
file. Pressing any other key would exit the batch file. This example
is for Windows 2000, XP and later users if you're running earlier
Windows 98 or earlier you'd need to use the
choice command.
Note: Simply replacing the "echo This is a loop" line with
your batch file will allow any of your batch files to loop or rerun.
