does anyone know why bash would suddenly start ignoring the $PS1 I export?

i have a .bashrc file that I move around with me to different machines, this time it just refuses to change the prompt

vindicator:~ bojan$ export PS1="\n\[$Blue\]\u\[$Color_Off\] at \[$Yellow\]\h\[$Color_Off\] in \[$Green\]\w\n\[$Color_Off\]> "
vindicator:~ bojan$ echo $PS1
\h:\W \u\$
vindicator:~ bojan$

is that bash or zsh? that doesn't look like bash PS1 syntax to me

it’s bash

it worked always

it doesn’t matter what i type

whatever i export PS1 to, it remains unchanged

i never saw this and have no idea why it would be broken this way

i have defined $Blue, $Color_Off etc. somewhere before that line

here, without the colors

vindicator:~ bojan$ export PS1="\n\u at \h in \w\n> "
vindicator:~ bojan$ echo $PS1
\h:\W \u\$

when I execute a subshell it works

vindicator:~ bojan$ PS1="\n\u at \h in \w\n> " bash

bojan at vindicator in ~
>

@bojan.matic: are you by chance using tmux?

no, this is in a pure iterm or Terminal session

no tmux

i am flabbergasted

it’s as if PS1 is silently read-only

strange...you might echo $PROMPT_COMMAND and the find the function that it gives you and follow it for clues.

vindicator:~ bojan$ echo $PROMPT_COMMAND
bash_prompt
vindicator:~ bojan$ which bash_prompt
vindicator:~ bojan$ type bash_prompt
bash_prompt is a function
bash_prompt ()
{
    PS1="$(build_prompt)"
}
vindicator:~ bojan$

i found it, i was sourcing oh-my-git before setting PS1

thanks

i moved some configs around so it ended up being sourced earlier
