Bash - how to put each line within quotation

Question

I want to put each line within quotation marks, such as:

abcdefg
hijklmn
opqrst

convert to:

\"abcdefg\"
\"hijklmn\"
\"opqrs         


        

Answer 1

paste -d\" /dev/null your-file /dev/null

(not the nicest looking, but probably the fastest)

Now, if the input may contain quotes, you may need to escape them with backslashes (and then escape backslashes as well) like:

sed 's/["\]/\\&/g; s/.*/"&"/' your-file
