How to combine 2 bash script into 1?
Hi all, I’ve quick question on bash scripting.

Here is my initial input. This is just an example. The value could be different numbers/ip addresses.

host.txt
Quote:
1.1.1.1
1.1.1.3
1.1.1.5
Final output should be like this.

output-final.txt
Quote:
create host_plain host1.1.1.1
modify network_objects host1.1.1.1 ipaddr 1.1.1.1
update network_objects host1.1.1.1
create host_plain host1.1.1.3
modify network_objects host1.1.1.3 ipaddr 1.1.1.3
update network_objects host1.1.1.3
create host_plain host1.1.1.5
modify network_objects host1.1.1.5 ipaddr 1.1.1.5
update network_objects host1.1.1.5
In order to have this, I’ve 2 different scripts.
The first one is just to append host in front of the ip.

script-1
Quote:
#!/bin/bash
awk '{
print "host"$1" "$1;
}' host.txt > output-1.txt
Second script is to create my final output.

script-2
Quote:
#!/bin/bash
awk '{
print "create host_plain " $1;
print "modify network_objects "$1" ipaddr " $2;
print "update network_objects "$1;
}' output-1.txt > output-final.txt
My question: Is it possible to combine this into one script so that I don’t have to run 2 different scripts?
If there is better way to do this, please let me know. Thanks in advance.

Try to extend your second script:
Code:
awk     '       {print "create host_plain host" $1;
                 print "modify network_objects host"$1" ipaddr " $1;
                 print "update network_objects host"$1;
                }
        ' file
create host_plain host1.1.1.1
modify network_objects host1.1.1.1 ipaddr 1.1.1.1
update network_objects host1.1.1.1
create host_plain host1.1.1.3
modify network_objects host1.1.1.3 ipaddr 1.1.1.3
update network_objects host1.1.1.3
create host_plain host1.1.1.5
modify network_objects host1.1.1.5 ipaddr 1.1.1.5
update network_objects host1.1.1.5

Does this do what you want?

Code:
IPS=$(echo 1.1.1-{1,3,5})
OUT=$HOME/tmp/output-final.txt

for IP in $IPS
do
	echo "create host_plain host $IP
modify network_objects host$IP ipaddr $IP
update network_objects host$IP
" >> $OUT
done

EDIT:
Ops, since the data is in a file:
Code:
OUT=output-final.txt
input_file=host.txt

while read IP
do
	echo "create host_plain host $IP
modify network_objects host$IP ipaddr $IP
update network_objects host$IP
" >> $OUT
done<$input_file

Hope this helps

Thanks guys for your prompt response. I really appreciate it. I forgot to mention on my first post that value of host.txt is just an example. It could be different ip addresses depending on what kind of ip addresses requested by user. Let me provide another set of ip addresses.

Instead of having 2 different scripts to get the final output, is it possible to combine them so that I can run a single script to produce the final output from the initial input?

Did you run the proposals against your new host.txt? As "single script"? What be the result?

Yes. E.g.
Code:
#!/bin/bash

awk '{
print "host"$1" "$1;
}' host.txt > output-1.txt 

awk '{
print "create host_plain " $1;
print "modify network_objects "$1" ipaddr " $2;
print "update network_objects "$1;
}' output-1.txt > output-final.txt

Yes. The awk command mentioned in posting #2 unifies your two awk commands. In fact, #3 does it too, just the other way.
