Hi All,
I need to search for a string in a file that I've opened and base a decision on the result. The logic is this:
"if the word 'Shared' appears on the first line then
do this on the whole file
else
do this on the whole file

bbhostgrep
BBHOSTGREP(1) General Commands Manual BBHOSTGREP(1)NAME
bbhostgrep - pick out lines in bb-hosts
SYNOPSIS
bbhostgrep --help
bbhostgrep --version
bbhostgrep [--noextras] [--test-untagged] [--bbdisp] [--bbnet] TAG [TAG...]
DESCRIPTION bbhostgrep(1) is for use by extension scripts that need to pick out the entries in a bb-hosts file that are relevant to the script.
The utility accepts test names as parameters, and will then parse the bb-hosts file and print out the host entries that have at least one
of the wanted tests specified. Tags may be given with a trailing asterisk '*', e.g. "bbhostgrep http*" is needed to find all http and https
tags.
The bbhostgrep utility supports the use of "include" directives inside the bb-hosts file, and will find matching tags in all included
files.
If the DOWNTIME or SLA tags are used in the bb-hosts(5) file, these are interpreted relative to the current time. bbhostgrep then outputs
a "INSIDESLA" or "OUTSIDESLA" tag for easier use by scripts that want to check if the current time is inside or outside the expected uptime
window.
OPTIONS --noextras
Remove the "testip", "dialup", "INSIDESLA" and "OUTSIDESLA" tags from the output.
--test-untagged
When using the BBLOCATION environment variable to test only hosts on a particular network segment, bbtest-net will ignore hosts that
do not have any "NET:x" tag. So only hosts that have a NET:$BBLOCATION tag will be tested.
With this option, hosts with no NET: tag are included in the test, so that all hosts that either have a matching NET: tag, or no
NET: tag at all are tested.
--no-down[=TESTNAME]
bbhostgrep will query the Xymon server for the current status of the "conn" test, and if TESTNAME is specified also for the current
state of the specified test. If the status of the "conn" test for a host is non-green, or the status of the TESTNAME test is dis-
abled, then this host is ignored and will not be included in the output. This can be used to ignore hosts that are down, or hosts
where the custom test is disabled.
--bbdisp
Search the bb-hosts file following include statements as a BBDISPLAY server would.
--bbnet
Search the bb-hosts file following include statements as a BBNET server would.
EXAMPLE
If your bb-hosts file looks like this
192.168.1.1 www.test.com # ftp telnet !oracle
192.168.1.2 db1.test.com # oracle
192.168.1.3 mail.test.com # smtp
and you have a custom Xymon extension script that performs the "oracle" test, then running "bbhostgrep oracle" would yield
192.168.1.1 www.test.com # !oracle
192.168.1.2 db1.test.com # oracle
so the script can quickly find the hosts that are of interest.
Note that the reverse-test modifier - "!oracle" - is included in the output; this also applies to the other test modifiers defined by Xymon
(the dialup and always-true modifiers).
If your extension scripts use more than one tag, just list all of the interesting tags on the command line.
bbhostgrep also supports the "NET:location" tag used by bbtest-net, so if your script performs network checks then it will see only the
hosts that are relevant for the test location that the script currently executes on.
USE IN EXTENSION SCRIPTS
To integrate bbhostgrep into an existing script, look for the line in the script that grep's in the $BBHOSTS file. Typically it will look
somewhat like this:
$GREP -i "^[0-9].*#.*TESTNAME" $BBHOSTS | ... code to handle test
Instead of the grep, we will use bbhostgrep. It then becomes
$BBHOME/bin/bbhostgrep TESTNAME | ... code to handle test
which is simpler, less error-prone and more efficient.
ENVIRONMENT VARIABLES
BBLOCATION
If set, bbhostgrep outputs only lines from bb-hosts that have a matching NET:$BBLOCATION setting.
BBHOSTS
Filename for the Xymon bb-hosts(5) file.
