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 --bs.

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 Frank

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.
