Copy output string to variable after multiple pipes

Question

Im trying to store the output of a set of commands to a variable in a shell script. The obvious backticks and eval are failing. Could someone help me out with this.

I want to store the output of

head -"$errno" tmptmptmp2 | tail -1 | sed 's/,//'

into a variable.

The command works fine BTW.

Yup.. heres what I get for bacticks , eval and $() line 20: =: command not found. — Laz

No need for the head/tail portion of the pipe. Just do: sed -n "${errno}s/,//p" — William Pursell

You can do:

var=$(head -"$errno" tmptmptmp2 | tail -1 | sed 's/,//')
