awk stringlength to shell

[bdittmar]

Must use /bin/sh (HP-UX 11i)

The variable $1 (string) has variable string length.
This length must be stored in a varable like $bl in the shell.

with echo $1 | awk '{print length($1)}' the variable length can be determined.
But how can i get this value back to the shell as $bl

Any idea ??

Use back-ticks ``

bl=`echo $1 | awk '{print length($0)}'`
