My BLFS 7.6 xterm window displays the wrong prompt, doesn't recognize
aliases, and doesn't allow sourcing scripts. Its prompt is "sh-4.3"
although I have PS1="/w >" in /etc/bashrc. Aliases don't execute and
attempting to source a script results in "file not found."
However, if I exclude the "*VT100*locale: true" line in
/etc/X11/app-defaults/XTerm" all problems disappear. With that one
change I have the correct prompt, can use aliases, and source scripts.
Although that fixes the problem, it still doesn't explain my error to me.
Everything else works quite well but I'm curious as to what I'm doing
wrong regarding X/xterm. I hadn't the problem prior to BLFS 7.5 and
don't see what I'm doing differently. Thoughts?
The terminal is not your problem. All the issues you mention have to do
with bash initialization.
First of all you need to realize that starting an xterm does not run
/etc/profile (or ~/.bash_profile, ~/.bash_login, ~/.profile) by default
because the terminal invocation of bash is not started as a login shell.
It only runs ~/.bashrc.
The /etc/bashrc file needs to be sourced explicitly from the ~/.bashrc file.
The easiest way to debug your initialization scripts is to add an echo
statement as the first line of each script and see what is used and the
order that they are run.
For example, place 'echo ~/.bashrc' in the ~/.bashrc file.
The aliases and PS1 (and PS2/3/4 if they are customized) need to be set
for every subshell as they are not inherited from a parent shell.
