sh Find the length of a string

Comment:

How do I set a variable to the character length of a string? I have tried several such as n=len($a) n=length($a) set n [string length $a] They do not seem to work.

You can find a string length any number of ways. The korn shell has a length operator: var="mystring" len=${#var} echo $len # shows 8 For older shells like the Bourne shell, you can also use external unix tools like awk or perl. Here's my favorite solution using expr: len=`expr $var : '.*'` echo $len

or you could do length=`echo -n "string" | wc -m` echo "length of string is $length"
