ls-ed some files today and noticed a few listed with blue backgrounds and white text. I use the
--color option to
ls because it's pretty, and because the colors provide information that's not always blindingly obvious from regular
ls output. Case in point, what did this blue background with white text mean?
It turns out that, at least for Ubuntu 9.10 an 10.04 (the two I tried), you can see a list of the colors that
ls uses for various things by typing:
Now, I had a hunch that these files were hardlinks, and sure enough, I saw this line:
HARDLINK 44;37 # regular file with more than one link
And looked up a few lines to see that, yes, 44 is blue and 37 is white. Cool. Just to be extra sure I passed the file names to the
stat command and saw the,
links: 2 for those files.
