2.com 1.2.0.1
3.com 1.3.0.1

I need to excute this command

You need a join, not a loop, a merge, so see man paste.
Code:
paste domain_list ip_list | while read i j
do
 /scripts/adddns --domain $I --ip $j
done

See, not two loops, a merge.

This isn't mine, I got it from someone on the boards here awhile back. This should consolidate two files just like you're asking. Maybe put this in your script and use the passed variables?

Code:
 
awk 'BEGIN {i=0 ; while (getline < "File1") { l[i]=$0 ; i++ } } ; { for (j=0 ; j<=i ; j++) { split(l[j],f) ; if (f[1] == $2) print $1,$2,f[2],$3,$4} }' File2

And I have never yet used the paste command! Real life does not do that!
