cooproces in command line

[ogniemi]

Hi,

i have a text file containing two below lines:
jfslog1_lv jfslog 1 2 2 open/syncd N/A
jfslog2_lv jfslog 1 2 2 open/syncd N/A


When I run below command I get 2 unexpected lines on output (first and last one). How to rid them off? Is the command syntax ok? Or maybe these to lines are also ok working with cooprocess?


$ cat lsvg.txt |& while read -p;do set `echo $REPLY`;echo "mklv -y'${1}' myvg ${3} raid10_l1";done
[1] 1261726
mklv -y'jfslog1_lv' myvg 1 raid10_l1
mklv -y'jfslog2_lv' myvg 1 raid10_l1
[1] + Done cat lsvg.txt |& while read -p;do set `echo $REPLY`;echo "mklv -y'${1}' myvg ${3} raid10_l1";done

your problem is marked in red:

cat lsvg.txt |[red]&[/red] while read -p;do set `echo $REPLY`;echo "mklv -y'${1}' myvg ${3} raid10_l1";done

oh! erase the & char.

Why not simply this ?
while read -p;do set `echo $REPLY`;echo "mklv -y'${1}' myvg ${3} raid10_l1";done < lsvg.txt

Hope This Helps, PH.
