cfajohnson ,, Thanks for ur reply .. I just tested the reassignment of the variable and it works great. But please remember , I have to print everything after the hostname until the occurence of the next host name on a new line. You reply does not address my question in full though is very useful ...So the output should be.
my input is assigned to variable i is as follow :
hostname1: text goes here hostname2: text goes here hostname3: text goes here
The output should be:
hostname1 text here
hostname2 text here
hostname3 text here

hostname
hostname(1) General Commands Manual hostname(1)
NAME
hostname - set or display name of current host system
SYNOPSIS
[name_of_host]
DESCRIPTION
The command displays the name of the current host, as given in the system call (see gethostname(2)). Users who have appropriate privileges
can set the hostname by giving the argument name_of_host; this is usually done in the startup script The name_of_host argument is
restricted to characters as defined in
The system might be known by other names if networking products are supported. See the node manager documentation supplied with your sys-
tem.
WARNINGS
If the name_of_host argument is specified, the resulting host name change lasts only until the system is rebooted. To change the host name
permanently, run the special initialization script (see
Many types of networking services are supported on HP-UX, each of which uses a separately assigned system name and naming convention. To
ensure predictable system behavior, it is essential that system names (also called host names or node names) be assigned in such a manner
that they do not create conflicts when the various networking facilities interact with each other.
The system does not rely on a single system name in a specific location, partly because different services use dissimilar name formats as
explained below. The and commands assign system names as follows:
+--------------+---------------+----------------+---------------------------+
|Node Name | Command | name Format | Used By |
+--------------+---------------+----------------+---------------------------+
|Internet name | hostname name | sys[.x.y.z...] | ARPA and NFS Services |
|UUCP name | uname -S name | sys | uucp and related programs |
+--------------+--------------+---------------+-----------------------+--|Node-+-Name-------|Command-------+ |name Format |Used By
| +--------------+--------------+---------------+-----------------------+ |Internet name |hostname name |sys[.x.y.z...] |ARPA and NFS Ser-
vices | |UUCP name |uname -S name |sys |uucp, related programs | +--------------+--------------+---------------+--------
--------------+
where sys represents the assigned system name. It is recommended that sys be identical for all commands and locations and that the
optional follow the specified notation for the particular ARPA/NFS environment.
Internet names are also frequently called host names or domain names (which are different from NFS domain names). Refer to hostname(5) for
more information about Internet naming conventions.
Whenever the system name is changed in any file or by the use of any of the above commands, it should also be changed in all other loca-
tions as well. Other files or commands in addition to those above (such as if used to circumvent for example) may contain or alter system
names. To ensure correct operation, they should also use the same system name.
System names are normally assigned by the script at start-up, and should not be altered elsewhere.
Setting a hostname of more than 64 bytes is possible only with the appropriate configuration options enabled. It is strongly recommended
that all related documentation be completely understood before setting a larger hostname. A hostname larger than 64 bytes can cause anoma-
lous or incorrect behavior in applications which use the command or the system function to access the name.
