          There is nothing that software can't fix. Unfortunately, there is also nothing that software can't completely fuck up. That gap is called talent.

          About Me

           

          Get the length of a string under UNIX/Linux

          there many ways to do so.

          str="hello world"

          len=`expr length ${str}`

          len=${#str}

          len=`echo ${str} | awk "{ print length }"`

          len=`echo -n ${str} | wc -c`
