[nzlug] Checking for directories that are symbolic links

[Johann Schoonees]

In bash scripts, how would I check if a directory name is a symlink or 
not?  The conditional in

if [ -d $dirname ]

evaluates to true whether dirname is a symlink or not.  I can think of 
roundabout ways like

if $(ls -F $dirname | grep -q "@")

but that would fail on filenames containing @, and

if [ "$(ls -F $dirname)" = "$dirname@" ]

is just as silly.  There must be a better way.

Googling "bash directory symlink conditional" gives 140,000 hits.  Sigh.
