Need to uncomment lines after the "############COMMENTED" match,
and comment lines after "#NFS static" but before "############COMMENTED".

I tried:

# i=$(df -Ph |egrep "fs5|fs1" |grep -v dmz |awk '{print $6}'); do var=$i; num=$(awk -v var="$var" '$2==var && $1 ~ /omhq11ad/{print $1}' fstab); sed "${num} s/# //" fstab; done

but that doesn't work. The lines to be uncommented and commented only need to be done if the filesystems are currently mounted.

Need to uncomment lines after the "############COMMENTED" match,
and comment lines after "#NFS static" but before "############COMMENTED"
awk 'f==1{sub(/^[^#]/,"#")}f==2{sub(/^#/,"")}/#NFS static/{f=1}/#COMMENTED/{f=2}1' fstab

Hope This Helps, PH.
