Surround all lines in a text file with quotes ('something')

Question

I've got a list of directories that contain spaces.

I need to surround them with ' ' to ensure that my batch scripts will work.

How can one surround each new line with a ' and a ' (quotes).

e.g.

File1:

/home/user/some type of file with spaces
/home/user/another type of file with spaces

To

File2:

'/home/user/some type of file with spaces'
'/home/user/another type of file with spaces'

Answer 1

Using sed:

sed -i "s/^.*$/'&'/g" filename

Answer 2

Use sed?

sed -e "s/\(.*\)/'\1'/"

Or, as commented below, if the directories might contain apostrophes (nightmare if they do) use this alternate

sed -e "s/'/'\\\\''/g;s/\(.*\)/'\1'/"

Answer 3

You can use sed(1) to insert single quotes at the beginning and end of each line in a file as so:

sed -i~ -e "s/^/'/;s/$/'/" the_file

Answer 4

very simple logic, you just need to echo the quotes in front and behind.

while read -r line
do
  echo "'$line'"
  # do something
done < "file"
