Strange read "error"
Good day.
I really hope U can help me with this as I'm stumped!
In the command line eg: read X; echo $x . Works perfectly fine.
Then running the same thing in my script it sometimes exiqute immediatly after pressing enter and continuiing. Not exiting the script I re-run the "read" section. Then after enterting some text. The curour jumps to the next line. I have to press enter 3-4 times before the script is running.
It's like there are 3/4 read's in a row, but the script only has one.
I've put echo's everywhere to find the problem, but the ONE read command creates random "read" instances. I can also just type 3-4 caracters and then the script continus to run.
VERY STRANGE!
Please help.
Here is the script so far.
#!/usr/bin/bash
key="Y"
#Display the email file with line number in it
function DISPLAYFILE {
nl EMAILADDYS
}
function REMOVE {
clear;
echo "Good day..."
echo
nl EMAILADDYS
echo
echo "Please select the number related to the email U would like to remove:"
read dn; echo $dn;
echo $dn
read;
#key="Y";
}
function ADDMAIL {
clear;
echo "ENTER STUFF:"
read newmail;
echo $newmail >> EMAILADDYS;
#key="Y";
}
DISPLAYFILE;
while [ $key != "X" ]; do
clear;
echo "GOOD DAY"
echo Below is the Email Addreses listed to recive the backup report
DISPLAYFILE;
echo "Please choose (A)dd or (R)emove or (E)exit."
printf ">"
read -n1 key
#echo $key
case $key in
a) ADDMAIL;;
A) ADDMAIL;;
R) REMOVE;;
r) REMOVE;;
e) echo "EXITING";
key="X";;
E) echo "EXITING";
key="X";;
*) echo "WRONG KEY PRESSED";
sleep 1;;
esac
done;
