Test the length of input string 1

[dickiebird]

Hi Experts
I need to check that users only input 4 chars in a script
eg

echo 'Please enter name (max 4 chars) \c '
read inname
if length(${inname} > 4)
echo '\nMax 4 chars please\n\n'
fi

Is there a test for length in ksh ???????
Thanks in advance

Indeed there is ... use the ${#....} syntax.

echo 'Please enter name (max 4 chars) \c '
read inname
if [ ${#inname} -gt 4 ]
then
echo '\nMax 4 chars please\n\n'
fi
