How do I make `ls` show file sizes in megabytes?

What commands do I need for Linux's ls to show the file size in MB?

Good Linux question — answering as the UphillTech team:

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 (10⁶ bytes) rather than MiB (2²⁰ 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. If you simply want file sizes in "reasonable" units, rather than specifically megabytes , then you can use -lh to get a long format listing and human readable file size presentation. This will use units of file size...
