Hi All,

I have been trying to format a file using sed. I can't seem to get the syntax right. I want to append the string from file1.txt to file1.csv with the final output file being file2.csv, but before the string is appended to the end of each line, first insert a comma.

Here is the sed command I'm running within the for loop:

for i in `cat file1.txt`
do sed 's/$/,'${i}'/' file1.csv > file2.csv
done


Below is an example of what I'm trying to accomplish:

file1.txt:
r2-1-config
r2-2-config
r2-3-config
r2-4-config
r2-5-config
r2-6-config
r2-7-config

r2-9-config
r2-10-config
r2-11-config

Thank you Ygor! The paste command and delimiter flag worked.
