[SOLVED] bash sed how to replace end of line with single quote and comma

Issue

I tried to replace end of lines in a file with single quote + comma.

Content of test.txt file:

aaa
bbb
ccc

Expected result:

aaa',
bbb',
ccc',

I managed to replace the end of lines with comma like this: sed 's#$#,#g' test.txt

but i always fail when trying to convert to single quote + comma. I tried: sed 's#$#',#g' test.txt but the command still awaiting input.

I tried various combination with quotes and double quotes but still fail.

I'd really appreciate your help. thanks.

Solution

Single quotes can't be nested. You have to end the single quotes, add an escaped or quoted single quote, than open a new quoted string.

sed 's/$/'\'',/'
sed 's/$/'"'"',/'

You can also switch the quotes and use double quotes for the whole expression:

sed "s/$/',/"

In fact, the substitution needs no quoting in this case, so you can just use

sed s/$/\',/
