I am new to unix and lerning tru cygwin (unix simulation on windows)

i am trying to lern sed command and want to interchange first and second no in a string. What i mean is

i am getting the following error

$ echo gauri 1234 556 | sed s/$[0-9]*$ $[0-9]*$/\2 \1/
sed: -e expression #1, char 10: unterminated `s' command

echo gauri 1234 556 | sed 's/$[0-9][0-9]*$ $[0-9][0-9]*$/\2 \1/'

Enclose the expression within single quotes.

vino
