How does one code an interactive response in this while loop?
#!/bin/bash
shows=$(< ${HOME}/.get_iplayer/tv.cache)
# ...
# ... stuff with shows omitted ...
# ...
function print_show {
# ...
return
}
while read -r line
do
print_show "$line"
read -n 1 -p "do stuff? [y/n] : " resp # PROBLEM
# ...
# resp actions omitted
# ...
done <<< "$shows"
So a file is read, "processed" then the resulting line oriented data is used in a while read
loop
But the read line within the while loop doesn't work as intended, that is it doesn't wait for the user response, presumably due to the while read
context it is encapsulated by.
Could you please suggest how to fix this or an alternate mechanism?
