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`
