Solve : Parameters at command line question?

Answer»

I know I can take parameters at command line LIKE:

file.bat param1 param2 etc

and have them read in file.bat like:

%1 %2 etc

but is there a way to pass parameters using options, i.e.:

file.bat -pOne param1 -pTwo -param2 etc

and have them read in file.bat, i.e. get value of pOne and pTwo?

Any help appreciatedif your asking what i think then you can just add

Code: [Select]set Pone=%1% which will then set your first parameter to "Pone".

on second thoughts that doesn't seem to be what your asking but if it is hope it works. If i get you right this time you want to pass a parameter to the batch file that TELLS the batch file to get a value?

this can be DONE but it depends where this value is in the first place.

FBfireballs, you had one % sign too many. To set Pone to the value of the first parameter you would use

set Pone=%1


No, what I'm thinking of is a way of kinda setting variables as they are passed, for example:

Code: [Select]file.bat -user myUserName -PASSWORD myPassword
would allow me to access the -user value that was passed, i.e. userName and the -password, i.e. myPassword.

I suppose the whole point of the exercise is to be able to swap around the options, such as:

Code: [Select]file.bat -password myPassword -user myUserName
but that this command would still mean the same as the previous command.
Actually, just thinking there, I could check each parameter, e.g.:

Code: [Select]while (input parameters)(
if %1 == -user
(
 do something with %2
)

if %1 == -password
(
 do something with %2
)


check that %3 is -password if %1 -user
OR
check that %3 is -user if %1 -password

do something with %4
)
Excuse the pseudocode.

Not as clean as I would have liked but still should do the job. Quote from: Dias de verano on August 27, 2008, 01:00:09 PM

fireballs, you had on % sign too many. To set Pone to the value of the first parameter you would use

set Pone=%1

It works either way for me.

you could have:

Code: [Select] if %%1=="-password" GOTO password
if %%1="-username" goto username
exit

:username
if not %%2=="My Username" (exit) else (
if not %%4=="My Password" exit
)
goto code

:password
if not %%2=="My Password" (exit) else (
if not %%4=="My Username" exit
)
goto code
is that what your looking for?

EDIT: i think we had the same idea, you posted as i was writing a response.

FBThat's the one, thought there might have been an actual command.

Thanks.While I was posting a reply, I saw the red "While you were typing a new reply has been posted" warning.

If you think about it logically, you only have 2 possibilities for the parameter sequence

(a) %1 -user %2 username %3 -password %4 password
(b) %1 -password %2 password %3 -user %4 username

So if you look at %1 you will find out all you need to know

Code: [Select]if "%1"=="-user" (
    set username=%2
    set password=%4
    ) else (
    set password=%2
    set username=%4
    )

I suppose my thinking was that using %1 - %9 can be limiting, mainly due to the amount of parameters that can be passed.
You can pass any number of parameters, you aren't limited to 9, as you will see if you study the SHIFT command.

Also, the %* parameter expands to a string made up of ***all*** of the parameters passed.


I see, so the SHIFT command will keep shifting through parameters, so I could have a large amount of them.

Nice one.
