Hello,
When using bash 5.3 as the shell for a user (/etc/passwd, chsh),
/etc/profile.d/vte-*.sh does not recognize interactive terminals. In my
case I'm simply installing 5.3 to /bin/bash.
Symptoms:
- '$-' is NULL (Sanity for vte.sh)
- $PROMPT_COMMAND does not include '__vte_prompt_command'
- Terminals behave as though PS1 contains non-visible chars that aren't
properly escape, even where PS1=''.
I had wanted to move away from using '${a[\#]' (I can't remember how I came
to this... I used to be smarter.) to make my exit-code indicators in the
PROMPT work by leveraging the new '${|foo;)' feature. No tangible gains
other than readability/maintainability for myself/others.
Prompt setup with handling for both <5.3 and 5.3.
Notes:
- That the issue with the term behaving as though PS1 contains improperly
escaped non-visible chars occurs for both versions of the PS1 prompt here.
- The <5.3 version of this PS1 cmd works on 5.2.37(1)-release and earlier.
