Unary operator expected through SSH

[jfernandz]

I haven't got any issue when I include screenfetch in my .bashrc but when this .bashrc is in a remote server and I connect it via SSH I get the following message:

/usr/bin/screenfetch: line 1341: [: =: unary operator expected

What's the output of screenfetch -v?

I also had the same warning. It's an easy fix (I don't think it's necessary to make a pull request)

Original Line 1341:
if [ $gpu = intel ]; then
Fix:
if [ "$gpu" = "intel" ]; then
Or (that one is only bash conform):
if [[ $gpu = intel ]]; then

Thanks for the info. The recent version already had the double brackets, but I've added the quotes anyway.
