Two other ways:

#!/bin/ksh

str="1234x"
len=$(expr "$str" : '.*')
echo $len
[code]

Another way:

[code]
#!/bin/ksh

str="1234x"
len=${#str}
echo $len

Sorry, I'll get it right ...

#!/bin/ksh

str="1234x"
len=$(expr "$str" : '.*')
echo $len

#!/bin/ksh

str="1234x"
len=${#str}
echo $len

echo $JAVA_HOME | wc -c

sorry if I'm nitpicking, but

echo $JAVA_HOME | wc -c

will squeeze multiple whitespace into just 1 space (not an issue for this variable but still...) and will add one newline char to the count.

echo "${JAVA_HOME}\c"|wc -c
or
echo -n "${JAVA_HOME}|wc -c

depending on how your echo works, seem more correct to me


HTH,

Yes, echo -n should be used, and few variables contain whitespaces:

echo $PROMPT_COMMAND | sed 's/[ \t]/_/g' | wc -c

If you have a postgresql database running, containing a database 'kram', containing a table 'dual', you could use:

psql -c "SELECT distinct length('$JAVA_HOME') from dual" kram

Here is another one, which works with bash.
I don't know whether with tcsh.

function stringLength
{
	echo $(($(echo $1 | sed 's/./+1/g')))
}
