UNIX for Dummies Questions & Answers

Hello
Any idea where is the error ?
*)
echo " Wrong selection. Try again "
continue
;;
esac
done
echo "Done"

Thanks alot

You can't have an "esac" unless you have a "case" first. Nor a "done" without a "do".

it gives an error like this
syntax error at line 43: `end of file' unexpected



the above code saws only the end of the script

ive got the case and do in my code

How to guess your whole script?

Pls. post your script to here.

echo " a.read a file"
echo " b.create a file"
echo " c.add on existing file"
echo " d. exit"
"; do
echo "Enter a,b,c or d: \c"
read answer
echo
case "$answer" in
a)

read answer
cat $answer
;;
b)

read answer
echo
cat> $answer
;;
c)

read answer
echo
cat>> $answer
;;
d)
break
;;
*)

continue
;;
esac
done
echo "Done"

What is the meaning of in line 5

Code:

"; do

??

You may use 'select' to do the same thing more convenience.

PS3="Enter your choice > "
select answer in "read a file" "create a file" "add on existing file" exit;
do
case "$answer" in
1)

read answer
cat $answer
;;
2)

read answer
echo
cat> $answer
;;
3)

read answer
echo
cat>> $answer
;;
4)
exit
;;
*)

print 'Invalid input'
;;
esac
done

I suppose this is what you were intending to do
