ls -l --block-size=M will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB.

If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.

If you don't want the M suffix attached to the file size, you can use something like --block-size=1M. Thanks Stéphane Chazelas for suggesting this.

This is described in the man page for ls; man ls and search for SIZE. It allows for units other than MB/MiB as well, and from the looks of it (I didn't try that) arbitrary block sizes as well (so you could see the file size as number of 412-byte blocks, if you want to).

Note that the --block-size parameter is a GNU extension on top of the Open Group's ls, so this may not work if you don't have a GNU userland (which most Linux installations do). The ls from GNU coreutils 8.5 does support --block-size as described above.

I'm a Ubuntu 16.04 user myself and I find that the <code>ll</code> command is by far the easiest way to see a directory's contents. I've noticed that not all Linux distributions support this command, but there's probably a workaround/install for each distro out there.

Example:

<pre><code>user@user-XPS-15-9560:/$ ll
total 188
drwxr-xr-x 27 root root 4096 Jan 26 09:13 ./
drwxr-xr-x 27 root root 4096 Jan 26 09:13 ../
drwxr-xr-x 2 root root 4096 Jan 22 15:13 bin/
drwxr-xr-x 4 root root 12288 Jan 29 11:35 boot/
drwxr-xr-x 2 root root 4096 Sep 3 18:14 cdrom/
drwxr-xr-x 20 root root 4440 Feb 5 08:43 dev/
drwxr-xr-x 153 root root 12288 Feb 2 15:17 etc/
drwxr-xr-x 4 root root 4096 Sep 3 18:15 home/
...
</code></pre>

The biggest advantage for me is that it's quick and really intuitive to use. 

UPDATE: what I didn't know was that on Ubuntu it's a pre-configured alias. You can easily set it yourself by executing <code>alias ll="ls -la"</code> on the command line, or by adding this entry in your .bashrc config file:

<pre><code>sudo nano ~/.bashrc
...add line described above and save file by pressing Ctrl+X and Y...
source ~/.bashrc
</code></pre>
