This is what I use: alias ls=‘ls -AF’
‘F’ puts little characters at the end of file names depending on what type of file it is. * for executables, / for directores, @ for softlinks and nothing for regular files. ‘A’ is the same as ‘a’ but it doesn’t show . or …
And speaking of “aliases”, they’re called softlinks in *nix terms.
You can also use man to find out a bunch of stuff: man ls
yerba# rm -rf /etc
