Terminal output below
Input to a file with the code, below are the results to filter out the part of the garbled characters, there is still a garbled characters ^ [,
I am confused ^ [is a character, whether filter ^ or [are not, and the characters in neovim, nano etc exist in the editor, also can search through the editor to ^ character, but with a plain text editor open does not exist
In addition, also want to consult the use of regular expressions or symbol in the shell code, I have tried a result=${result///|/}, the result=${result///|/}, the result=${result//[\ |]/}, the result=${result///\ \ |/}, etc., the results are not correct
