Solve : Handle ampersand "&" inputted by user in batch file.? |
|
Answer» I have a batch file that takes user input and places it in a variable. The problem is that sometimes the user may enter an "&" symbol which then causes the script to TRY to process the string after the & as a command. I need the script to take the ampersand and place it variable string and then convert it to url encoding. For example: I see you posted an almost similar question in the Computer Programming category. The code is basically the same as what Salmon Trout had posted for you for the spaces. Not sure why you didn't attempt to modify his code for the Ampersand replacement. I actually did, but with the code: Code: [Select]echo off & setlocal enabledelayedexpansion set /p "variable1=Enter Input:" set "variable2=!variable1:&=%%26!" set "variable3=!variable2: =%%20!" set "variable4=!variable3:,=%%2c!" echo %variable1% echo %variable2% echo %variable3% echo %variable4% pause I get the output: Code: [Select]Enter Input:you, me, & them you, me, 'them' is not recognized as an internal or external command, operable program or batch file. you, me, %26 them you,%20me,%20%26%20them you%2c%20me%2c%20%26%20them Press any key to continue . . . Because the input has an Ampersand you either need to enclose it in quotes or use Delayed EXPANSION to ECHO the contents. Code: [Select]echo off & setlocal enabledelayedexpansion set /p "variable1=Enter Input:" set "variable2=!variable1:&=%%26!" set "variable3=!variable2: =%%20!" set "variable4=!variable3:,=%%2c!" echo %variable1% echo "%variable1%" echo !variable1! echo %variable2% echo %variable3% echo %variable4% pauseoutput Code: [Select]Enter Input:you, me, & them you, me, 'them' is not recognized as an internal or external command, operable program or batch file. "you, me, & them" you, me, & them you, me, %26 them you,%20me,%20%26%20them you%2c%20me%2c%20%26%20them Press any key to continue . . .And there is also the SET /P trick, which doesn't require the use of Delayed Expansion. Code: [Select]echo off & setlocal enabledelayedexpansion set /p "variable1=Enter Input:" set "variable2=!variable1:&=%%26!" set "variable3=!variable2: =%%20!" set "variable4=!variable3:,=%%2c!" set /p ".=%variable1%"<nul echo/ echo %variable2% echo %variable3% echo %variable4% pauseoutput Code: [Select]Enter Input:you, me, & them you, me, & them you, me, %26 them you,%20me,%20%26%20them you%2c%20me%2c%20%26%20them Press any key to continue . . . |
