gnu grep/bsd grep: bsd doesn't support a few completely useless options (-z, -u, --mmap, --include, --exclude, --exclude-from), and some aliases for options that it does support (-d for --directories, -r for -R, --colour for --color)

gnu tar/bsd tar: bsd tar is a lot faster

gnu awk/bsd awk: gnu awk is broken unless you use the --posix option, with --posix it's just a bit slower than bsd awk

gnu ls/bsd ls: gnu ls has a few options that no one ever uses (--si, --show-control-chars, etc.)
