[csreekanthreddy508]

Hi Friends,

      I want to assign the ouput of sed followed by cut command to a variable.I am using the syntax as follows.


           a=`sed -n "1p" filename | cut -c1-30`
          echo $a

         Please help me regarding this.

Thanks in advance

you don't need to use 2 tools to get the first 30 characters. use head

Code: [Select]

a=$(head -c30 file)
echo $a
