Question about EOF and newline

[cmolson]

Hey I have a question/problem I am encountering. I need to write a bash script which will exit when a EOF is read in using the read command.
Here is what I have so far:

read -p "Enter Name: " -e namein

if [ "$namein" == "^D" ]
then
     echo "ctrl-d detected, exiting"
     exit
fi

I don't know how I can catch the ctrl-d because it is not a ascii character, and is not signal that can be trapped.

Any ideas? Thanks!

welcome to the forum

if read has no input, it returns 1 ("Learning the Bash Shell," Newham &
Rosenblatt, p.172) so you could try something like this:

if read -p "Enter Name: " namein
then echo $namein
else echo -e "\nctrl-d detected, exiting"
fi

entering "^d" returns 1 (false) so the else path is taken. The "-e"
option to echo turns on interpretation of the "\n" purely for neatness.

thanks for the interesting question
