Appending text, written in variable, below current line using sed

  • 772

I can append text below current line, using the sed editor:

$ foo=bar
$ echo "some text"|sed "a\bar"
some text
bar

But when I try to append text from variable below current line, using sed, I am not able to do it:

$ foo=bar
$ echo "some text"|sed "a\$foo"
some text
$foo
command-line

    Escape the dollar sign using a backslash (\):

    $ echo "some text"|sed "a\\$foo"
some text
bar

    Works fine here.
