df hide ifree, iused, 512 blocks (customize column format, don't show inode info) My default df invocation prints way too much information for my needs. I can't find a way to hide this in the man page. It says use the -i flag to include it. But when I execute /usr/local/bin/df I get this:

How do I hide all these extra columns? (come to think of it, how do I get rid of those useless map -static rows too?)

Extra info:

uname -a output:

Darwin myusername-Mac-mini.local 15.3.0 Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58 PST 2015; root:xnu-3248.30.4~1/RELEASE_X86_64 x86_64 i386 Macmini6,1 Darwin
The standard macOS df supports an -P option (which suppresses most of the things you don't want) so you could run

df -P | grep -v 'map -static'


Explanation of option (from man df):

-i  Include statistics on the number of free inodes.
    This option is now the default to conform
    to Version 3 of the Single UNIX Specification
    (``SUSv3'') Use -P to suppress this output.

-P  Explicitly  use 512 byte blocks, overriding any BLOCKSIZE specifi-
    cation from the environment.  This  is the same as the -b option.
    The -k option overrides this option.
