Awk writes shell distribution scripts

When you use Hadoop or deploy Hadoop, you often encounter situations where you want to copy files to other machines, but if the individual writes, it happens that the cluster is large and exhausting, and now uses an awk to write shell scripts that are fast

Command

awk ' begin{

Print "#! /bin/sh "; for (i=10;i<=200;i++) print" Scp-r Hadoop 10.6.8. " I ":/usr/hadoop"

} ' > scp.sh

This makes it easy to distribute 190 machines such as 10.6.8.10~10.6.8.200.

OK, we can use it.
