Sorry for such a dreadful title, but I'm not sure how to be more descriptive. I'm hoping some of the more gurutastic out there can take a look at a solution I came up with to a problem, and advice if there are better ways to have gone about it.

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
As an example I've written a script called question (The fist command is to show what is the contents of the... (2 Replies)
Hi Im running this script, which is supposed to find the max value build some tables and then stop running once all the tables are built. Thing is , it keeps assigning a null value to $h and then $g is null so it keep building tables i.e. testupdateNUL. How can I stop this? Here is what I have:

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)
Hi,
hope I am posting in the right section.
My problem is that I have 2 or more arguments passed and I want to check if the arguments passed exists or not.
The first argument should not exist and the remaining others should exist.
example:
./shells.sh argument1 argument2 argument3

Hi, I was debating if I should put this in the dummies or scripts section, I apologize in advance if I chose poorly.
Fairly new to Unix and BASH scripting but I thought I made it fairly well given my limited understanding. However, the output indicates that it's looping and I'm ending up with a... (5 Replies)

Hi all,
i developed a script to measure the uptime of a process in a Solaris 10/11 environments.
All is well, but i came across a situation where there are multiple processes of the same name. Basically i have the following result file:

dbd::gofer::transport::base
DBD::Gofer::Transport::Base(3) User Contributed Perl Documentation DBD::Gofer::Transport::Base(3)NAME
DBD::Gofer::Transport::Base - base class for DBD::Gofer client transports
SYNOPSIS
my $remote_dsn = "..."
DBI->connect("dbi:Gofer:transport=...;url=...;timeout=...;retry_limit=...;dsn=$remote_dsn",...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY='dbi:Gofer:transport=...;url=...'
which will force all DBI connections to be made via that Gofer server.
DESCRIPTION
This is the base class for all DBD::Gofer client transports.
ATTRIBUTES
Gofer transport attributes can be specified either in the attributes parameter of the connect() method call, or in the DSN string. When
used in the DSN string, attribute names don't have the "go_" prefix.
go_dsn
The full DBI DSN that the Gofer server should connect to on your behalf.
When used in the DSN it must be the last element in the DSN string.
go_timeout
A time limit for sending a request and receiving a response. Some drivers may implement sending and receiving as separate steps, in which
case (currently) the timeout applies to each separately.
If a request needs to be resent then the timeout is restarted for each sending of a request and receiving of a response.
go_retry_limit
The maximum number of times an request may be retried. The default is 2.
go_retry_hook
This subroutine reference is called, if defined, for each response received where $response->err is true.
The subroutine is pass three parameters: the request object, the response object, and the transport object.
If it returns an undefined value then the default retry behaviour is used. See "RETRY ON ERROR" below.
If it returns a defined but false value then the request is not resent.
If it returns true value then the request is resent, so long as the number of retries does not exceed "go_retry_limit".
RETRY ON ERROR
The default retry on error behaviour is:
- Retry if the error was due to DBI_GOFER_RANDOM. See L<DBI::Gofer::Execute>.
- Retry if $request->is_idempotent returns true. See L<DBI::Gofer::Request>.
A retry won't be allowed if the number of previous retries has reached "go_retry_limit".
TRACING
Tracing of gofer requests and reponses can be enabled by setting the "DBD_GOFER_TRACE" environment variable. A value of 1 gives a
reasonably compact summary of each request and response. A value of 2 or more gives a detailed, and voluminous, dump.
The trace is written using DBI->trace_msg() and so is written to the default DBI trace output, which is usually STDERR.
METHODS
This section is currently far from complete.
response_retry_preference
$retry = $transport->response_retry_preference($request, $response);
The response_retry_preference is called by DBD::Gofer when considering if a request should be retried after an error.
Returns true (would like to retry), false (must not retry), undef (no preference).
If a true value is returned in the form of a CODE ref then, if DBD::Gofer does decide to retry the request, it calls the code ref passing
$retry_count, $retry_limit. Can be used for logging and/or to implement exponential backoff behaviour. Currently the called code must
return using "return;" to allow for future extensions.
