SED Replace character with '

Question

Trying to put ' before each line of text and ' at the end of each line of text.

I have been using sed 's/^/1/' file.txt to replace to begging of each line and sed 's/$/0/' file.txt to replace the end of each line.

What I am trying to make work is sed 's/^/'/' and sed 's/$/'/'

This would format my file to make each line reach as a command, when applied to a separate script.
