Problem here is that sed treats $ as a special characer meaning end of line as well as the korn shell meaning variable replacement.

To avoid the shell evaluation, use ' not ". to avoid the sed special charater, escape it.

echo '123$45$678' | sed 's/\$/\\\$/g'

Hi:

I have a quick question about replacing "$" with "\$" on unix. I need to convert string "123$45$678" to "123\$45\$678" through a pipe. I tried with sed command, but could not get it to work:

essex$ echo "123$45$678" | sed s/"$"/"\$"/g 123578$
essex$ echo "123$45$678" | sed s/"$"/"\\$"/g 123578$

Maybe there is another syntax that I should use? TIA.
