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

Code:

sed -e 'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/' -e "s/^/\'/" -e "s/$/\'/" file

it worked properly

another:

Code:

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

output:

Code:

# ./test.sh
'jolly mirani'
'han lee'
'stuart lloyd'
