Question Using awk and sed to replace text

Good Day Every one

I have a problem finding and replacing text in some large files that will take a long time to manually edit.

Example text file looks like this

#Example Large Text File
Code:
unix
linux
dos
squid
bind
dance
bike
car
plane

What im trying to do is to edit all the lines at the same time and add " " to each line so it would look like this.

#Example Large Text File
Code:
"unix"
"linux"
"dos"
"squid"
"bind"
"dance"
"bike"
"car"
"plane"

i managed to use sed to change one line but then i need to know what the text in the line is to change it.

Code:
sed -i 's/bind/"bind"/g' large-txt-file

So what i want to do is to change all the lines regardless of what the text on that line is.

i have tried
Code:
sed -i 's/*/"*"/g' large-txt-file

and
Code:
awk '{sub(*, "*")};' large-text-file

Im new to using awk and sed.

Any help would be greatly appreciated.

Smilie

For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
