Character Count in script
Code:
#!/bin/ksh
read name
read mobile

echo $name | wc -m
Nunberchar=`echo $name |wc -m`

echo $Nunberchar

I write something above, however the char count is wrong, it always count the $ , how to avoid it ?

Please check your echo man page, there may be an option to supress printing of new line character

It does not count the $ - how could it; there is no dollar in $name. BUT - it counts the newline char that echo sends after $name

for me the following works
Code:
 
echo "$name\c" | wc -m

BTW - why don't you use the shell builtin parameter length function
Code:
$ echo ${#name}
5

which you can immeditely assign to another variable or evaluate in a test, if need be.
