All the questions and answers i already read are not my solution. So, all i want to do is to replace the special char ' in bash.

This works:

A="abc"

B="${A//[b]/x}"

But this does not work:

A="a'b"

B="${A//[']/'}"

Also, i have tried:

B="${A//[']/\'}"

B="${A//[']/\'}"

B="${A//[']/'''}"

B="${A//[']/'\''}"

But B keeps to be a'b.

This way works:

A="a'b"

B="${A//'/\'}"

Two notes:

1. The [] are unnecessary when only one character is inside of them


2. You need to escape and ' inside of the substitution.
