Answer / swaroopa
The test command is particularly useful in this context
allowing a variety of conditions to be checked for. There
are two equivalent syntaxes.
test expression
and
[ expression ]
The following simple example will list all the
subdirectories of the current directory.
for i in *
do
if [ -d $i ]
then
echo $i
fi
done
