Hi

I have to write a shell script to accept a string, check for vowels and display it on screen.

How do i write it? Thanks

Please post what you've done so far with questions about the trouble spots and someone would be glad to help you.

Try:

#!/bin/ksh
typeset -i x=1

read string?"please Enter String:"
Char=`echo $string | cut -c ${x}-${x} `

while [ -n "${Char}" ]
do
case ${Char} in
a|A|e|E|i|I|o|O|u|U )
echo "${Char}\c"
;;
esac
x=x+1
Char=`echo $string | cut -c ${x}-${x} `
done
echo

No RISK no FUN

I have a bit of a different approach. Seems to work a bit faster, less memory intensive.

#!/bin/ksh
read string?"Enter a String: "
lcstring=$(print $string | tr "[:upper:]" "[:lower:]")
print $lcstring | tr "a" "A" | tr "e" "E" | tr "i" "I" | tr "o" "O" | tr "u" "U" | tr -d "[:lower:]"

Its only 3 lines so you have:
read ....
lcstring ....
then the last line is
print ....

You COULD make it two lines, but the second line would be humongous. You can also make it a few more lines, but, IMHO, this should be ok.
