put strings around the file name



i have a file(old file) with names in it like
jolly mirani
han lee
stuart lloyd

i want string to be added to these names . new file should look like
'jolly mirani'
'han lee'
'stuart lloyd'

i tried using sed command but doesn't work for string but it do work for paranthesis. can some one help me with the code for the same.

sed 's/[^][^]*/(&)/g' <old file> new file

another:

code:

awk ' {  $0 = tolower($0); print "\047"$0"\047"} ' "file"
output:

code:

# ./test.sh
'jolly mirani'
