replace two character strings by two variables with sed command
Hello,

I want to writte a script that replace two character strings by two variables with the command sed butmy solution doesn't work. I'm written this: sed "s/TTFactivevent/$TTFav/g && s/switchSLL/$SLL/g" templatefile.
I want to replace TTFactivevent by the variable $TTFav, that is a number, and switchSLL by $SLL in the file templatefile.
Have you not any solution ?

Thanks

I have already tried and it's doesn't work.
The command replaces TTFactivevent by $TTFav but $TTFav is a number and I want the number not the name of the variable. Do you have any idea ?

Did you single quotes or double quotes around substitute command?

Double quotes works while single quotes replace TTFactivevent by variable $TTFav instead of its value
