Playing with byobu & bashrc i messed up bashrc. Since then “ls” not showing any colors and it was very difficult and irritating to identify, directories, binaries and files. to fix this issue use “—color=auto” with ls, You’ll see blue , green and black colors as usual. Using this log command instead of “ls” is a pain so simply add an alias to basic and your problem is solved.

ubuntu@ubuntu:~/tmp$ vim  ~/.bashrc
ubuntu@ubuntu:~/tmp$ alias ls='ls --color=auto'
ubuntu@ubuntu:~/tmp$ source ~/.bashrc
Now type only “ls” and you’ll see colors. gil ...
