  • 0

So let’s say I have this variable %s% and I have to take out all the symbols because they will interffere with the code.. These symbols include:

~`!@#$%^&*()_-+={[}]|\:;”‘<,>.?/

So basically every symbol I can think of typing, how should I go about doing this? The following code was a HUGE failure

SET s=!s:"^~"=""!
SET s=!s:"`"=""!
SET s=!s:"^!"=""!
SET s=!s:"@"=""!
SET s=!s:"#"=""!
SET s=!s:"^$"=""!
SET s=!s:"^%"=""!
SET s=!s:"^^"=""!
SET s=!s:"&"=""!
SET s=!s:"*"=""!
SET s=!s:"("=""!
SET s=!s:")"=""!
SET s=!s:"-"=""!
SET s=!s:"_"=""!
SET s=!s:"+"=""!
SET s=!s:"="=""!
SET s=!s:"{"=""!
SET s=!s:"}"=""!
SET s=!s:"["=""!
SET s=!s:"]"=""!
SET s=!s:"^|"=""!
SET s=!s:"\"=""!
SET s=!s:":"=""!
SET s=!s:";"=""!
SET s=!s:"'"=""!
SET s=!s:'"'=""!
SET s=!s:"<"=""!
SET s=!s:","=""!
SET s=!s:">"=""!
SET s=!s:"."=""!
SET s=!s:"?"=""!
SET s=!s:"/"=""!

I’ve scoured the internet and found nothing, any ideas?

    A first step can be this, it remove all chars from the badChars-list and also the exclamation mark.
    But the characters ~*= can’t be replaced this way.

    set "str=Hello,;:$%%!&<>x"
setlocal EnableDelayedExpansion

set "badChars=`@#$%%^&()_-+{[}]|\:;'<,>.?/""
for /L %%n in (0,1,30) do (
  for /f "eol=A delims=" %%C in ("!badChars:~%%n,1!") DO (
    if defined str set "str=!str:%%C=!"
  )
)
set "str=%str:!=%"
echo(!str!
