#
IFS=' :'
# Looping over lines in the file, fo each line read name, a, b, and c.
# "sed 1d" command deletes first line to skip over header ("Vname vport")
#
sed 1d file1 | while read name a b c ; do
# If it was an empty line, skip and loop to next line
#
[ "$name" ] || continue
# output the variables for demonstration
#
echo "name: $name"
echo "a = $a"
echo "b = $b"
echo "c = $c"
# extra line to separate output of next line

echo
