Given such situation:
echo "Please enter your name" read name # user enters: john smith echo $name # prints: john
What could cause
read to read only the first word of the input?
Is there a shell variable that controls this?
I came across this in a question on Ask Ubuntu and I'm wondering how to reproduce this behavior.
$IFSor filename generation. But
echoconcats on spaces - and so even for multiple args they should come together. I can imagine if it was an extra quote level deep - like an ssh script or something it might lose some - but that's fuzzy.
echoshould at least print the args unless
$IFSis composed of all of the alphabetics or something.
printf, on the other hand, would only print john or 123 in that scenario, though.
