a specific string substitution
hi guys...need some help here...
i am making a a script to automatically install netbackup client...so its gonna write a configuration file according to the host name.... the line would be something like this
CLIENT_NAME = odel_bkp.test.com
the thing is ...the host name in reallity is odel.test.com , if i do a echo "CLIENT_NAME = `/bin/hostname`" > bp.conf , i wont have the odel_bkp like i want , is there a way to make this string "_bkp" be added just after the hostname and before the domain name?
thanks

atusername
atuser(3) AtFS Toolkit Library atuser(3)
NAME
atUserValid, atScanUser, atUserName, atUserUid - user handling
SYNOPSIS
#include <atfs.h>
#include <atfstk.h>
void atScanUser (char *userName; Af_user *resultUser);
char* atUserName (Af_user *user);
Uid_t atUserUid (Af_user *user);
int atUserValid (Af_user *user);
DESCRIPTION
atScanUser scans the given string userName and tries to derive an AtFS user identification (resultUser) from it. It does not verify the
existence of a corresponding UNIX (/etc/passwd) user entry. Use atUserUid to test that. atScanUser understands the following formats:
user When the string does not contain an at sign, it is considered to be a plain user name from the current host and domain.
user@host In the case that the part after the at sign doe not contain a period, it is assumed to be a hostname. Domain is the current
domain.
user@host.domain
This format can only be recognized, when the given domain is equal to the current domain, and the hostname remains as rest
between the at sign and domain name.
user@domain
An user identification string with a domain name different to the local domain is treated as user@domain, although this might
be wrong.
atUserName returns a string of the form user@domain generated from the given user structure. If no domain name is given in the structure,
it returns user@host instead. With no host and no domain name, just user is returned. The result string resides in static memory and will
be overwritten on subsequent calls.
atUserUid tries to map the given user structure to a UNIX user identification. It returns the uid on success, -1 otherwise.
atUserValid checks the given user structure for plausibility. It returns FALSE on fauilure, a non null value on success.
