Echo with loop
Hello
i have a file with this format:

ip.txt content:
Code:
192.168.1.1/2020
192.136.1.2/2028
192.168.1.10/3047

....

need to create 1000 files and each files content, import data from ip.txt line (first file with first line data, second file with second line...etc)

Code:
internal=yes
internalip= (IP FROM FILE)
internal.dest: (IP FROM FILE) port=(PORT FROM FILE)

im confuses how add loop when try to echo.

Dear nimafire,

I have a few to questions pose in response first:-
  • Is this homework/assignment? There are specific forums for these.
  • What have you tried so far?
  • What output/errors do you get?
  • What OS and version are you using?
  • What are your preferred tools? (C, shell, perl, awk, etc.)
  • What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.


We're all here to learn and getting the relevant information will help us all.


Kind regards,
Robin

mm this is my personal script
i have create file with 1000 line with this format:
ip/port like 192.168.1.1/1055, let say ip.txt and create a core.sh file

main part of this project is when core.sh execute, it read ip and port from ip.txt and create 1000 files with this pattern:

config1 config2 config3

and echo this to each of files:

Code:
internal=yes
internalip= $ip
internal.dest: $ip port=$port

OS/LANG: centos/shell

Try
Code:
awk '                                                                      
        {split ($0, IP, "/")
         printf "internal=yes\ninternalip=%s\ninternal.dest:%s port=%s\n", IP[1], IP[1], IP[2] > ("FILE" NR)
        }
' file

        {split ($0, IP, "/")
         printf "internal=yes\ninternalip=%s\ninternal.dest:%s port=%s\n", IP[1], IP[1], IP[2] > ("FILE" NR)
        }
' file

Unless you know that file will never contain more than about nine lines, I would add a close() statement to that:
Code:
awk '                                                                      
        {split ($0, IP, "/")
         printf "internal=yes\ninternalip=%s\ninternal.dest:%s port=%s\n", IP[1], IP[1], IP[2] > ("FILE" NR)
         close("FILE" NR)
        }
' file

to keep from running out of file descriptors.
