Accepting Upper and Lower case

Hi Gurus,

This is my script:

echo ""
echo "Do you want to execute DWH Test Program?"
echo ""
echo -n "Okay?("y" or "n")=> "
set ret = $<

if ($ret != "y") then
echo ""
echo ""
echo "End."
exit 0

How can I make this script accept uppercase as well? Cos if I type a "Y" it will not recognise and end the program.

Thanks.

You could convert the input string to...
all upper case and test for uppercase Y only
all lower case and test for lowercase y on;y
use the "or" in your if statememt "$ret" != "y" || "$ret" != "Y"

Hi Andrek,

Many thanks for your contribution.

what do u mean by the following sentence:

"You could convert the input string to...
all upper case and test for uppercase Y only
all lower case and test for lowercase y only" ?

i have tried using or in my if statement but they are not giving me the expected result...actually the whole script looks like this:

echo "Do you want to execute DWH Test Program?"
echo ""
echo -n "Okay?("y" or "n")=> "
set ret = $<

if ("$ret" != "y" || "$ret" != "Y") then
echo ""
echo ""
echo "End."
exit 0
endif

echo ""
echo "---- DWH Program is running --------"
echo ""

/bin/rsh -n -l smtadm 140.32.12.34 /spsummit/apl/summit/nss_tools/scripts/test.csh >& /dev/null

Once the prog check if its Yes or No then it will either exit or execute another script.

any advise? thanks again.

wee

change that to

Code:
if ("$ret" != "y" && "$ret" != "Y") then

&& is required to be used with !=, ("$ret" != "y" || "$ret" != "Y") will always result in true.

Hi my comments
"all upper case and test for uppercase Y only, or
all lower case and test for lowercase y only"

ret=`echo $ret | tr "[:lower:]" "[:upper:]"`
if [ "$ret" != "Y" ]....

or

ret=`echo $ret | tr "[:upper:]" "[:lower:]"`
if [ "$ret" != "y" ]....

or

"Revsisied - Thanks Vish"
if ("$ret" != "y" && "$ret" != "Y")...

Cheers

You should either declare your input variables as uppercase or lowercase:


Code:
typeset -l INPUT1   # everything will be lowercase
typeset -u INPUT2   # everything will be UPPERCASE

Or, you can test for multiple choices at once:


Code:
if [[ $INPUT == @(Y|y)* ]]; then
  echo Yep
elif [[ $INPUT == @(N|n)* ]]; then
  echo Nope
else
  echo WhatThe
fi

Note that the astersisk allows you to accept "yes" and "YES" (or "y" + anything).
