first of all, thanks to all on this board, it has been a huge resource to answer most of my questions!
I am stuck on something that should really be simple, and was looking for some help.. I am using KSH on solaris and working on a script to move containers from server to server. Where i am having problems is setting a variable that should equal a different variable based on the answer..
ie
basically i have $zone1 $zone2 etc set in the script already, so i just need $ZONENAME=$zone(?) based on which number they select
when i run it i get this:
so it looks like it is close... Where am i going wrong, or is there a better way to accomplish this?
I am writing a shell script that executes another script by fetching it over the network and piping its contents into sh (ftp -o - $script | sh; or wget -O - |sh). Since this bypasses putting the script on the filesystem, this means I can't source the script directly (using . ), but rather it... (1 Reply)
Okay this is a mess, I'm trying to assign variables with variables in a for-loop. Here is what i have for code. The syntax is not good.
Given the following script:

foreach site (ABC DEF GHI)
eval set \t$${site}sf = ``wc -l \$${site}.sf | awk '{print $1}'``
eval set... (2 Replies)
Hi -
I'm trying to think of a clever way to write a shell script (trying to stay w/ ksh as that's what I know the best...) that will resolve the following problem:

Hi,
Could any one share the intelligence to track this problem.
I have any array BT_META_36 and it prints properly with contents of array.
# print "BT_META_36=${BT_META_36}"
# BT_META_36=cab3,cab4:HDS:052,07A cab3,cab4:HDS:052,07A
Now I have a BT_META_36 assigned to a variable.... (0 Replies)
Hi,
I came across a post wherein you can use "set -r"(on bash) to activate restricted mode ( wherein you cant run some commands such as cd etc).
Can anyone guide if we have anything similar in ksh ?
Thanks (2 Replies)

RRDp(3) User Contributed Perl Documentation RRDp(3)NAME
RRDp - Attach RRDtool from within a perl script via a set of pipes;
SYNOPSIS
use RRDp
RRDp::start path to RRDtool executable
RRDp::cmd rrdtool commandline
$answer = RRD::read
$status = RRD::end
$RRDp::user, $RRDp::sys, $RRDp::real, $RRDp::error_mode, $RRDp::error
DESCRIPTION
With this module you can safely communicate with the RRDtool.
After every RRDp::cmd you have to issue an RRDp::read command to get RRDtools answer to your command. The answer is returned as a pointer,
in order to speed things up. If the last command did not return any data, RRDp::read will return an undefined variable.
If you import the PERFORMANCE variables into your namespace, you can access RRDtool's internal performance measurements.
use RRDp
Load the RRDp::pipe module.
RRDp::start path to RRDtool executable
start RRDtool. The argument must be the path to the RRDtool executable
RRDp::cmd rrdtool commandline
pass commands on to RRDtool. Check the RRDtool documentation for more info on the RRDtool commands.
Note: Due to design limitations, RRDp::cmd does not support the "graph -" command - use "graphv -" instead.
$answer = RRDp::read
read RRDtool's response to your command. Note that the $answer variable will only contain a pointer to the returned data. The
reason for this is, that RRDtool can potentially return quite excessive amounts of data and we don't want to copy this around in
memory. So when you want to access the contents of $answer you have to use $$answer which dereferences the variable.
$status = RRDp::end
terminates RRDtool and returns RRDtool's status ...
$RRDp::user, $RRDp::sys, $RRDp::real
these variables will contain totals of the user time, system time and real time as seen by RRDtool. User time is the time RRDtool
is running, System time is the time spend in system calls and real time is the total time RRDtool has been running.
The difference between user + system and real is the time spent waiting for things like the hard disk and new input from the Perl
script.
$RRDp::error_mode and $RRDp::error
If you set the variable $RRDp::error_mode to the value 'catch' before you run RRDp::read a potential ERROR message will not cause
the program to abort but will be returned in this variable. If no error occurs the variable will be empty.
$RRDp::error_mode = 'catch';
RRDp::cmd qw(info file.rrd);
print $RRDp::error if $RRDp::error;
EXAMPLE
use RRDp;
RRDp::start "/usr/local/bin/rrdtool";
RRDp::cmd qw(create demo.rrd --step 100
DS:in:GAUGE:100:U:U
RRA:AVERAGE:0.5:1:10);
$answer = RRDp::read;
print $$answer;
($usertime,$systemtime,$realtime) = ($RRDp::user,$RRDp::sys,$RRDp::real);
