A short while ago, I saw a blog post from someone about modernizing their shell. Unfortunately, I lost the blog post, but there was some really good stuff in there. Just mentioning this in case someone knows what I’m talking about.
One tweak I remember they mentioned was about fixing programs that have broken formatting. It prevents scenarios like
user@hostname:~$ echo "hi"
hiuser@hostname:-~$
where the output and shell prompt get placed on the same line. I noticed this happens with bash with C programs that don’t include a \n in the final printf statement.
Get a term app that does all the things for you, install ohmyzsh or fish or something, then learn that thing.
There is no universal or worthwhile catchall for any of this because it’s so subjective. Find what works for you, and get good at it.
Seconding fish shell. Very nice experience and the only real downside (or upside depending on perspective) is the non-POSIX syntax for some things.
