How can I pass arguments to a batch file?

Question

I need to pass an ID and a password to a batch file at the time of running rather than hardcoding them into the file.

Here\'s what the command line looks like:

Answer 1

Paired arguments

If you prefer passing the arguments in a key-value pair you can use something like this:

@echo off

setlocal enableDelayedExpansion

:::::  asigning arguments as a key-value pairs:::::::::::::
set counter=0
for %%# in (%*) do (    
    set /a counter=counter+1
    set /a even=counter%%2
    
    if !even! == 0 (
        echo setting !prev! to %%#
        set "!prev!=%%~#"
    )
    set "prev=%%~#"
)
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

:: showing the assignments
echo %one% %two% %three% %four% %five%

endlocal

And an example :

c:>argumentsDemo.bat one 1 "two" 2 three 3 four 4 "five" 5
1 2 3 4 5

Predefined variables

You can also set some environment variables in advance. It can be done by setting them in the console or setting them from my computer:

@echo off

if defined variable1 (
    echo %variable1%
)

if defined variable2 (
    echo %variable2%
)

and calling it like:

c:\>set variable1=1

c:\>set variable2=2

c:\>argumentsTest.bat
1
2

File with listed values

You can also point to a file where the needed values are preset. If this is the script:

@echo off

setlocal
::::::::::
set "VALUES_FILE=E:\scripts\values.txt"
:::::::::::


for /f "usebackq eol=: tokens=* delims=" %%# in ("%VALUES_FILE%") do set "%%#"

echo %key1% %key2% %some_other_key%

endlocal

and values file is this:

:::: use EOL=: in the FOR loop to use it as a comment

key1=value1

key2=value2

:::: do not left spaces arround the =
:::: or at the begining of the line

some_other_key=something else

and_one_more=more

the output of calling it will be:

value1 value2 something else

Of course you can combine all approaches. Check also arguments syntax , shift
