in reply to Send Bash Command

For some reason or other, I've never thought about changing my prompt's color, but I have changed my CPAN prompt(see: Trick or Treat). Here's the easiest way that I know to change the bash prompt color using perl:
#!/usr/bin/perl use strict; use warnings; use ExtUtils::MakeMaker qw(prompt); prompt("export PS1=\e[0;31m\][\\u@\\H\\W\]\$\\e]m");
When you run it, it'll change the color to red, then it'll appear to hang. Actually, as with any command, bash is waiting for <enter>. To get back to your former color, just exit the terminal and start another one.

    Out of curiosity, I tried your script in Linux OS and it seems to work. But if you do a 'ls', the red prompt turns back to black. Anyway, I think it is a good attempt.
      That's interesting. If you do a 'man ls', the man page turns to black. But when you 'q', it goes back to red:). I think that "prompt" is basically good for the first command. Then you need to switch to something like 'system' as in this work-around:
      #!/usr/bin/perl use strict; use warnings; use ExtUtils::MakeMaker qw(prompt); prompt("export PS1=\e[0;31m\][\\u@\\H\\W\]\$\\e]m"); system("ls");
      However, I like the idea of using 'ls' to return to the former color. It's quicker than restarting the terminal:).
