Here is my task: read some data from file line by line. For each line, if it satisfies some condition, then ask user to input something and proceed based on the user's input.
I know how to read content line-by-line from a shell script:
while read line; do echo $line done < file.txt However, what if I want to interact with the user inside the loop body. Conceptually, here is what I want:
while read line; do echo "Is this what you want: $line [Y]es/[n]o" # Here is the problem: # I want to read something from standard input here. # However, inside the loop body, the standard input is redirected to file.txt read INPUT if [[ $INPUT == "Y" ]]; then echo $line fi done < file.txt Should I use another way to read file? or another way to read stdin?
