I am trying to remove '$' signs from a string, but I am guessing it is some special char? I am extremely new to lua (just started coding in it today). From my understanding this should work and does for other chars string.gsub(line,'$','').

Similarly, if you String contains many special characters, you can remove all of them by just picking alphanumeric characters e.g. replaceAll("[^a-zA-Z0-9_-]", ""), which will replace anything with empty String except a to z, A to Z, 0 to 9,_ and dash.
To remove multiple characters from a string we can easily use the function str. replace and pass a parameter multiple characters. The String class (Str) provides a method to replace(old_str, new_str) to replace the sub-strings in a string. It replaces all the elements of the old sub-string with the new sub-string.
In Python you can use the replace() and translate() methods to specify which characters you want to remove from a string and return a new modified string result. It is important to remember that the original string will not be altered because strings are immutable.
You can remove a character from a Python string using replace() or translate(). Both these methods replace a character or string with a given value. If an empty string is specified, the character or string you select is removed from the string without a replacement.
yup, that's a special character for pattern matching. you need to escape it with the % symbol.
local s = 'asdf$erer$iiuq'
print(s:gsub('%$', ''))
