In my current situation, it is not unusual for me to have several UNIX computers I connect to, as several different users depending on the situation, and to traverse through various directories on the machines doing things. I use ksh through the entire thing.
I was fiddling with my prompt recently, and I was able to get it to change some colors depending on my current username and current server. However, what I would also want is for it to change colors based on my current directory. For example, if I were in directory "foo", the prompt should be yellow, but if I were in directory "bar", the prompt would be magenta. In both cases, subdirectories should also count, so a simple substring check should be enough.
The problem I ran into, however, is that when I run my .profile script, it properly colors the directory--but it no longer dynamically updates whenever I switch to another directory--and I'm not sure how before I did all the branching, I was able to get it to print my current working directory correctly even after I switched directories.
I did some googling, and find information for bash, but ksh seems to be largely ignored. As I cannot figure out how to do this on my own, I must bring it to the Stack Overflow community, to add it to future knowledge. Thus, with my long-winded explanation, the "quick version" of my question is as follows:
In ksh, how can I set up my prompt to display the current working directory and color the text based on where the current working directory is? Is it even possible?
I was able to dig up a semi-solution here:
Though enacting it is still difficult.
