How do get ls to list directories with a trailing forward-slash?

Question

My shell is bash. How can I get the output of ls to show directories with a trailing forward-slash? When I do ls in tcsh it gives the desired output. How can I get this to occur in bash without using any arguments?

eg.

bin/
lib/
src/
file1.txt
file2.txt

Answer 1

The simplest solution (as given already by @don_crissti in the comments) is:

ls -p

You can get a similar effect with:

ls -F

But that will add some other indicators as well:

Append a character to each file name indicating the file type. Also, for regular files that are executable, append *. The file type indicators are / for directories, @ for symbolic links, | for FIFOs, = for sockets, > for doors, and nothing for regular files.

---

Of course, you can make the string ls execute ls -p on the command line with an alias:

alias ls='ls -p'

That is temporal and could be erased with unalias ls.
Probably your tcsh has an active alias in place.

Which you can do by placing the command in ~/.bashrc or ~/.bash_aliases.

Answer 2

You can use -F, e.g.

$ /bin/ls -F
-/                                 diesel_folks                 grub                     presidents             user_mailer/
0/                                 dmStaffing/                  HJJJH/                   prime_scenarios   
...
# I'm using /bin/ls to make sure I run my system ls 
# (I actually have it aliased to add options automatically normally)
#
# Just read about your no argument requirement
# So you too could alias it, i.e.

alias ls='ls -F'

# Put it in your `.bashrc` or `.bash_aliases` file

Answer 3

Either

   ls --classify

Or:

   ls --indicator-style=slash

Explanation

   -F, --classify
          append indicator (one of */=>@|) to entries

   -p, --indicator-style=slash
          append / indicator to directories

The other answers more or less cover this, but I prefer GNU-style long options over BSD-style short options in Stack Overflow answers since they are more self-explanatory and learnable / "memorizable" / "internalizeable".

Answer 4

On many systems like Ubuntu you can use the l command. It by default shows all of the directories with a forward slash. It actually is an alias for ls -CF (as you can find out by running alias). These kind of aliases are usually defined in ~/.bashrc (in case you want to modify them or add additional ones).
