I have an issue with my terminal prompt line. When the line is too long it wraps on the same line and then Up arrow makes it look even worse.

I have already checked Terminal prompt not wrapping correctly,
but it looks like I am apparently closing all the squared brackets for non printable characters.

This is my PS1:

[e]0;u@h: wa]$debian_chroot:+($debian_chroot) [33[01;36m]u@h[33[00m]33[01;34m]w33[00m][$(type __git_ps1 >/dev/null 2>&1 && __git_ps1 "(%s)")]

Consider this as my standard prompt line

MELISC@work~/dev/bin_tools[((main))]

I was able to get

assdasdasdasdasdadasdsadadasdaddasdadadasdadsadasdsa((main))] asdsadsadsadsadasdasdassdasdasdassdasdassdasdasdasdasdasdasdsadsad

I have already checked my .bashrc

I have and shopt -s checkwinsize should autocheck the columns

You've completely banjanxed the Bourne Again shell's idea of what's been printed and what it has to erase/rewrite as it displays command history and lets you edit the command line.

Breaking your prompt down into sections:

1. 
   [e]0;u@h: wa] — non-printing characters, properly enclosed


2. 
   $debian_chroot:+($debian_chroot) — printing characters only, presumably


3. 
   [33[01;36m] — non-printing characters, properly enclosed


4. 
   u@h — printing characters only


5. 
   [33[00m] — non-printing characters, properly enclosed


6. 
   33[01;34m] — non-printing characters, improperly enclosed so the Bourne Again shell does not know that they are


7. 
   w33[00m] — an erroneous mixture of printing and non-printing characters


8. 
   [$(type __git_ps1 >/dev/null 2>&1 && __git_ps1 "(%s)")] — printing characters only, presumably

I've given this advice before, but it is general advice that applies here as well:

• Use either e or 33 consistently, for your own sanity.


• Make your [ and ] strictly matching non-nesting pairs.


• Make sure that all non-printing sequences are within [ and ] (and that, conversely, that all printing sequences are not).

(This is why I personally prefer the Z Shell and its alternative prompt expansion mechanism for when I want wacky coloured prompts. It knows that things like %Fgreen aren't printing sequences, without having to be told; and it also works out the correct escape sequences from terminfo, without having them hardwired.)
