Is there any way to ask the user which variable wants to be shown and display it? It should be, as a concept, something like this:
#echo off
set "VAR_1=THIS IS VAR_1"
set "VAR_2=THIS IS VAR_2"
set /p "VAR_TO_SHOW=Enter the variable to show: (VAR_1/VAR_2)"
echo %%VAR_TO_SHOW%%
So if we are in "echo %%VAR_TO_SHOW%%" if we entered "VAR_1" I would want to look like this:
echo %VAR_1%
So the output would be "THIS IS VAR_1". Summarizing all what I've said, I would want to make a variable inside a variable. How can I make this?
Another thing I would want to comment is that I've alredy tried "%%!VAR!%%" and "%%VAR%%" without the exclamation marks, but what is displayied is or "%!VAR_TO_SHOW!%" or the same but without (again) the exclamation marks...
#echo off
set "VAR_1=THIS IS VAR_1"
set "VAR_2=THIS IS VAR_2"
set /p "VAR_TO_SHOW=Enter the variable to show: (VAR_1/VAR_2)"
call echo %%%VAR_TO_SHOW%%%
or
#echo off
setlocal enableDelayedExpansion
set "VAR_1=THIS IS VAR_1"
set "VAR_2=THIS IS VAR_2"
set /p "VAR_TO_SHOW=Enter the variable to show: (VAR_1/VAR_2)"
echo !%VAR_TO_SHOW%!
the second way will work faster.
I've seen it done before on someone else's Batch program, so I'm sure it's possible. Every time I launch my program I run a series of lines of code such as:
set/a num=0
set/a tog=1
set/a ran=%random% %%10 +1
However, I would like for certain variables to stay around, even after the program is closed. I need scripts that can:
Write in a separate document the values of certain variables
Check that document for values at any point in any usage session
Thanks in advance!
You need a save system like so:
(
echo %VARIABLE1%
echo %VARIABLE2%
echo %VARIABLE3%
echo %VARIABLE4%
echo %VARIABLE5%
) > LOGS.prgmsav
The file extension can be .txt or something weird like .nerfguns, to load LOGS.prgmsav:
< LOGS.prgmsav (
set /p VARIABLE1=
set /p VARIABLE2=
set /p VARIABLE3=
set /p VARIABLE4=
set /p VARIABLE5=
)
The VARIABLE is any variable, you can save as many as you want! I hope I helped!
I've just started with batch file programming and testing variable usage momentary.
Does anyone know what is the difference between the 2 variable calls, the space before the last %
#echo off
set pathOS1="\\o1511\Pcs7ProjectO1511\OS1511\GraCS\"
ECHO We're working with %pathOS1%
ECHO We're working with %pathOS1 %
since the echo is different:
We're working with "\\o1511\Pcs7ProjectO1511\OS1511\GraCS\"
We're working with \\o1511\Pcs7ProjectO1511\OS1511\GraCS\
Delayed expansion is not enabled.
Spaces are allowed in the variable name.
set "data=100"
set "data =101"
echo %data%
echo %data %
set data
You have two variables with two similar values
So I summarize your answers:
This can happen if there's no setlocal at the start of the routine, any values set in the environment remain set, so if "pathos1 " was set previously, its value will be retained until it's cleared by a set "pathos1 =" statement or cmd is closed.
So, since I didn't close the cmd and didn't set setlocal, I called the previously set variable "pathos1 =".
It is good example for setlocal :)
I'm running this command and I don't see why it won't work
setlocal EnableDelayedExpansion
for %%a in (harry-boy) do set %%a:-==
echo %harry%
pause
And this is the result I get -
e:\6\1>setlocal EnableDelayedExpansion
e:\6\1>for %a in (harry-boy) do set %a:-==
e:\6\1>set harry-boy:-==
e:\6\1>echo
ECHO is on.
e:\6\1>pause
Press any key to continue . . .
I'm changing the hyphen sign to a equals sign then running the set command on that. I expect to see that the variable "harry" = "boy"??
Here is a simple test -
set file=play=here.mkv
set %file:==-%
echo %file%
pause
and I get this -
set file=play=here.mkv
==-%
was unexpected at this time.
set %file:==-%
I thought I would get the new contents of file = play-here.mkv. Ok, I see that this makes the syntax wrong and the set command stops. So how do I change the = to a hyphen?
The string replacement format:
%var:old-string=new-string%
does NOT work on for replaceable parameters, just in Batch variables. The equivalent way for your example, using a variable instead, would be:
set a=harry-boy
set %a:-==%
echo %harry%
pause
Output:
C:>set a=harry-boy
C:>set harry=boy
C:>echo boy
boy
C:>pause
Press any key to continue . . .
Easy soloution:
for /f "tokens=1,2 delims=-" %%a in ("harry-boy") do set %%a=%%b
Echo %harry%
And that should do your job for you. But it will only work with one - in the quote.
SET will assign the value on the right of the first = to an environment variable named on the left.
Hence you would be assigning a value of = to a variable named harry-boy:- in BOTH cases.
You can verify this by executing
set harr
which will display any variable starting harr
Can anybody help with effective and safe way of removing quotes from batch variables?
I have written a batch file which successfully imports a list of parameters %1, %2, %3 etc. and places them into named variables. Some of these parameters contain multiple words, and therefor are enclosed in double quotes.
> "Susie Jo" (%1)
> "Smith Barnes" (%2)
> "123 E. Main St." (%3)
These %variables are next placed in named variables:
> set FirstName=%1
> set LastName=%2
> set ShipAddr=%3
verification of variables is done by echo.
> echo.%FirstName%
> echo.%LastName%
> echo.%ShipAddr%
results display as
"Susie Jo"
"Smith Barnes"
"123 E. Main St."
I need to eliminate the included quotes on selected variables. For instance, FirstName and LastName are used elsewhere and must not include quotes.
In a test batch file I was successful at eliminating quotes using the ~tilde character in variables.
> set FirstName=%~1
> set LastName=%~2
I thought I had the solution, but I soon experienced unusual behavior with execution of batch files. Suddenly CMD is no recognizing long path statments. Normal execution of batch file from full path
> C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
returns
> 'C:\Documents' is not recognized as an internal or external command....
So it would appear that the addition of the ~tilde character to the in-coming %1 %2...%n variables has caused some change. Possibly some environment variables have been altered?
I also tried clearing quotes from within variable with various attempts using the FOR command. That seems awkward and I have been unable to learn how to accomplish this by creating a list of variable to perform the task:
something like this:
for %%g in (%FirstName% %LastName%) do (
set %%g=%%~g
set %%h=%%~h
set FirstName=%%~g
set LastName=%%h
echo.%FirstName% %LastName%
)
I think I have two issues.
My 'short and sweet' idea of inserting ~tilde in the incoming %1 %2 variables (%~1, etc) seems to have affected some settings and altered how CMD navigates long pathnames.
I'm still in search of a clean and easy way to eliminate quotes from selected named variables.
Any help for those more experienced would be most appreciated. I'm at the end of my skills here... need some guidance please!

You have an extra double quote at the end, which is adding it back to the end of the string (after removing both quotes from the string).
Input:
set widget="a very useful item"
set widget
set widget=%widget:"=%
set widget
Output:
widget="a very useful item"
widget=a very useful item
Note: To replace Double Quotes " with Single Quotes ' do the following:
set widget=%widget:"='%
Note: To replace the word "World" (not case sensitive) with BobB do the following:
set widget="Hello World!"
set widget=%widget:world=BobB%
set widget
Output:
widget="Hello BobB!"
As far as your initial question goes (save the following code to a batch file .cmd or .bat and run):
#ECHO OFF
ECHO %0
SET BathFileAndPath=%~0
ECHO %BathFileAndPath%
ECHO "%BathFileAndPath%"
ECHO %~0
ECHO %0
PAUSE
Output:
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
Press any key to continue . . .
%0 is the Script Name and Path.
%1 is the first command line argument, and so on.
Your conclusion (1) sounds wrong. There must be some other factor at play.
The problem of quotes in batch file parameters is normally solved by removing the quotes with %~ and then putting them back manually where appropriate.
E.g.:
set cmd=%~1
set params=%~2 %~3
"%cmd%" %params%
Note the quotes around %cmd%. Without them, path with spaces won't work.
If you could post your entire batch code, maybe more specific answer could be made.
I usually just remove all quotes from my variables with:
set var=%var:"=%
And then apply them again wherever I need them e.g.:
echo "%var%"
Spent a lot of time trying to do this in a simple way.
After looking at FOR loop carefully, I realized I can do this with just one line of code:
FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I
Example:
#ECHO OFF
SET Quoted="Test string"
FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I
ECHO %Quoted%
ECHO %Unquoted%
Output:
"Test string"
Test string
The simple tilde syntax works only for removing quotation marks around the command line parameters being passed into the batch files
SET xyz=%~1
Above batch file code will set xyz to whatever value is being passed as first paramter stripping away the leading and trailing quotations (if present).
But, This simple tilde syntax will not work for other variables that were not passed in as parameters
For all other variable, you need to use expanded substitution syntax that requires you to
specify leading and lagging characters to be removed. Effectively we are instructing to remove strip away the first and the last character without looking at what it actually is.
#SET SomeFileName="Some Quoted file name"
#echo %SomeFileName% %SomeFileName:~1,-1%
If we wanted to check what the first and last character was actually quotation before removing it, we will need some extra code as follows
#SET VAR="Some Very Long Quoted String"
If aa%VAR:~0,1%%VAR:~-1%aa == aa""aa SET UNQUOTEDVAR=%VAR:~1,-1%
I learned from this link, if you are using XP or greater that this will simply work by itself:
SET params = %~1
I could not get any of the other solutions here to work on Windows 7.
To iterate over them, I did this:
FOR %%A IN (%params%) DO (
ECHO %%A
)
Note: You will only get double quotes if you pass in arguments separated by a space typically.
This sounds like a simple bug where you are using %~ somewhere where you shouldn't be. The use if %~ doesn't fundamentally change the way batch files work, it just removes quotes from the string in that single situation.
All the answers are complete. But Wanted to add one thing,
set FirstName=%~1
set LastName=%~2
This line should have worked, you needed a small change.
set "FirstName=%~1"
set "LastName=%~2"
Include the complete assignment within quotes. It will remove quotes without an issue. This is a prefered way of assignment which fixes unwanted issues with quotes in arguments.
set widget="a very useful item"
set widget
widget="a very useful item"
set widget=%widget:"=%"
set widget
set widget=a very useful item"
The trailing quote " in line 4 is adding a quote " to the string. It should be removed.
The syntax for line 4 ends with %
I thought I had the solution, but I soon experienced unusual behavior with execution of batch files. Suddenly CMD is no recognizing long path statments. Normal execution of batch file from full path
C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
returns
'C:\Documents' is not recognized as an internal or external command....
There's your whole problem. CMD doesn't understand spaces inside of filenames from the command line, so it thinks you're trying to pass
and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
as parameters to the
"C:\Documents"
program.
You need to quote it to run a batch file with spaces in the path:
> "C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat"
would have worked.

Demonstrates with or without quotes reguardless of whether original parameter has quotes or not.
And if you want to test the existence of a parameter which may or may not be in quotes, put this line before the echos above:
If '%1'=='' goto yoursub
But if checking for existence of a file that may or may not have quotes then it's:
If EXIST "!1!" goto othersub
Note the use of single quotes and double quotes are different.
Azure devops sometimes uses double quoting character (") to specify string. Powershell can use single quote character (') to specify string. Naturally I wanted to have a flexibility to be able to specify parameters however I wish, so same parameter can be used from both - command line - via batch file, and as a powershell script, as any parameter, including empty value.
Quote natural thinking is to write something like this:
build.bat:
#echo off
setlocal enabledelayedexpansion
set args=%*
set args=%args:"='%
echo powershell -executionpolicy bypass "%~dpn0.ps1" %args%
endlocal
But like you can guess - this does not work out of box - if no arguments are provided to batch file so %* == empty string. args expands as no string, and next replacement notices that args is not set - and instead of replacing string - it would append extra "=' garbage to args parameter.
Solution to this was just to add extra space in first assignment.
build.bat:
#echo off
setlocal enabledelayedexpansion
set args=%*
set args=%args:"='%
echo powershell -executionpolicy bypass "%~dpn0.ps1" %args%
endlocal
After this character translation should be correct:
C:\test>build
powershell -executionpolicy bypass "C:\test.ps1"
C:\test>build aa
powershell -executionpolicy bypass "C:\test\build.ps1" aa
C:\test>build "aa"
powershell -executionpolicy bypass "C:\test\build.ps1" 'aa'
C:\test>build 'aa'
powershell -executionpolicy bypass "C:\test\build.ps1" 'aa'
