I am unsure of when this problem began, which has made it hard diagnose, but I have very strange and incorrect characters in my terminal prompt. I will not give the exact characters, but it involves punctuation/special characters:

’[e[1

I'm very confused at why this might be. I'm using bash in High Sierra, but I believe this problem may have persisted over an upgrade.

Output of echo $PS1 is

’[e[1

It was a mistake in ~/.bash_profile that I must have made when trying to configure colour differences in bash:

PS1=`\[\e[1;32m\][\u@\h \W]\$\[\e[0m\]`

This uses back-ticks instead of apostrophes. I commented out the lines pertaining to bash prompt and the problem is solved.

    The string should be in single-quotes ('), not commas (,) or backticks. Also, it needs to be plain ASCII single-quotes, not the fancy unicode curly quotes (like ‘, ’, or ‛). Commented Jan 9, 2023 at 3:44
