Read 2 input and produce it in single ouput?
Hi all.
I’ve 2 inputs here and would like to produce it in single ouput. I’ve drafted simple shell script but not sure how to put all this together. The final output should be “GROUP-XYZ” instead of “TEST”
Please advise.

INPUT1
Code:
GROUP-XYZ

INPUT2
Code:
type8code0@box:~/dbedit$ cat port.txt
80
443
type8code0@box:~/dbedit$


Expected output
Code:
type8code0@box:~/dbedit$ ./dbedit-script-service-group
   create service_group GROUP-XYZ
   create service_group GROUP-XYZ '' services:tcp80
   create service_group GROUP-XYZ '' services:tcp443
   type8code0@box:~/dbedit$

DRAFT SHELL SCRIPT
Code:
#!/bin/bash
   
   awk '{print "tcp"$1}' port.txt > temp-port.txt
   
   awk '{
   print "create service_group TEST";
   print "create service_group TEST \x27\x27 services:"$1;
   }' temp-port.txt

Unfortunately, this is not the expected output. Need to fix something on the draft code so that expected output can be produced. Please advise.
Code:
type8code0@box:~/dbedit$   ./dbedit-script-service-group
   create   service_group TEST
   create   service_group TEST '' services:tcp80
   create   service_group TEST
   create service_group   TEST '' services:tcp443
   type8code0@box:~/dbedit$

Hi, maybe this could work for you.

Code:
awk '
BEGIN { print "create service_group TEST"; }
{ print "create service_group TEST \x27\x27 services:tcp"$1 }' port.txt

This is definitely better than my initial draft code Smilie
Is it possible to replace “TEST" with any variable?

E.g.
Code:
Please type your new service group name: GROUP-XYZ

Final Output:
Code:
create service_group GROUP-XYZ
  create service_group GROUP-XYZ '' services:tcp22
  create service_group GROUP-XYZ '' services:tcp80
  create service_group GROUP-XYZ '' services:tcp443

With awk you could try something like this:
Code:
awk 'NR==FNR{A[$1]; next} {print s, $1; for(i in A) print s, $1, t i}' s="create service_group" t="'' services:tcp" file2 file

But perhaps shell script would do just fine here?
Code:
while read service_group
do
  printf "create service_group %s\n" "$service_group"
  while read port
  do
    printf "create service_group %s '' services:tcp%s\n" "$service_group" "$port"
  done < file2
done < file1

But perhaps a simple bit of shell script would do just fine here?
Code:
while read service_group
do
  printf "create service_group %s\n" "$service_group"
  while read port
  do
    printf "create service_group %s '' services:tcp%s\n" "$service_group" "$port"
  done < file2
done < file1

I've tested and both solutions work like a charm. Thanks a lot SmilieSmilie

Since file1 only contains single word, is it possible to use interactive way. I was thinking something like this.

Please let me know how to combine this code into yours.
Code:
type8code0@box:~/dbedit$ cat test
echo -n "Enter new group name : "
read g
echo "You entered: $g"
type8code0@box:~/dbedit$

Code:
type8code0@box:~/dbedit$ ./test
Enter new group name : GROUP-XYZ
You entered: GROUP-XYZ
type8code0@box:~/dbedit$

You're welcome... You could adjust the shell loop like so, leaving out the first input file and reading from the terminal instead..
Code:
while 
  printf "Enter new group name : "
  read service_group
do
  printf "You entered: %s\n" "$service_group"
  printf "create service_group %s\n" "$service_group"
  while read port
  do
    printf "create service_group %s '' services:tcp%s\n" "$service_group" "$port"
  done < file2
done

This is perfect. Thanks again. SmilieSmilieSmilieSmilie

Quick question, how to stop this loop besides using combination of Ctrl + C?

Code:
type8code0@box:~/dbedit$ ./test
Enter new group name : XYZ
You entered: XYZ
create service_group XYZ
create service_group XYZ '' services:tcp22
create service_group XYZ '' services:tcp80
create service_group XYZ '' services:tcp443
Enter new group name :
You entered:
create service_group
create service_group  '' services:tcp22
create service_group  '' services:tcp80
create service_group  '' services:tcp443
Enter new group name : ABC
You entered: ABC
create service_group ABC
create service_group ABC '' services:tcp22
create service_group ABC '' services:tcp80
create service_group ABC '' services:tcp443
Enter new group name :
