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.
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 :

services
SERVICES(5) BSD File Formats Manual SERVICES(5)NAME
services -- service name data base
DESCRIPTION
The services file contains information regarding the known services available in the DARPA Internet. For each service a single line should
be present with the following information:
official service name
port number
protocol name
aliases
Items are separated by any number of blanks and/or tab characters. The port number and protocol name are considered a single item; a ``/''
is used to separate the port and protocol (e.g. ``512/tcp''). A ``#'' indicates the beginning of a comment; subsequent characters up to the
end of the line are not interpreted by the routines which search the file.
Service names may contain any printable character other than a field delimiter, newline, or comment character.
INTERACTION WITH DIRECTORY SERVICES
Processes generally find service records using one of the getservent(3) family of functions, or using getaddrinfo(3). On Mac OS X, these
functions interact with the DirectoryService(8) daemon, which reads the /etc/services file as well as searching other directory information
services to determine service name, protocol, and port information.
FILES
/etc/services
SEE ALSO getservent(3), getaddrinfo(3), DirectoryService(8)HISTORY
The services file format appeared in 4.2BSD.
