I recently found that on Mac OS X I can set this up in my shell ~/.profile so that when I use grep it will print the matches in color (white one red).

alias grep='GREP_COLOR="1;37;41" LANG=C grep --color=auto'

But setting up an alias seems like kind of a hack way to do this. Previously I had tried with no luck:

export GREP_COLOR=always           # works fine in Linux

And then I also tried:

export GREP_COLOR="1;37;41"

Is there a better way to do this than setting up an alias?

I don't see the point of your question. An alias is how you do this. That's what it's for. export the environment variable e.g. in .bash_profile, and define alias grep='grep --color', and you're done. – Daniel Beck Apr 25 '12 at 18:05

Per Grep_color on mac as suggested by @lupincho, this seems to work fine and does not use an alias:

export GREP_OPTIONS='--color=always'
export GREP_COLOR='1;35;40'

Didn't work for me. :( – trusktr Nov 25 '14 at 23:04
    
Did you restart your terminal ? – Mike Nguyen Jul 16 '15 at 8:31

Have a +1 for this as a good solution, however setting GREP_OPTIONS leads to grep: warning: GREP_OPTIONS is deprecated; please use an alias or script. Something like this is now preferred: alias grep="`which grep` --color=always" – joelittlejohn Nov 6 '15 at 12:06
    
@joelittlejohn doesn't work when using grep in pipes with xargs, eg: find /usr/share -name '*.txt' |xargs grep testing – rfabbri May 27 at 15:29
