OT: unix script quetion: to replace $ with \$

[Guang Mei]

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.
