How to redirect the import log to /dev/null?
Hi
i am running oracle database import through a script and script scans the import log to see if there are any errors.
Now the porblem is that when i run the script the import log appears on the screen even if i direct the output of import to /dev/null.
imp "'/ as sysdba'" file=${exp_file} log=${RUN_PATH}/imp_${db}_${dt}.log parfile=config.par > /dev/null
i tried adding 2>&1 > /dev/null to the end but then the log appears in the log file instead of the screen ,which the script builds with
exec > ${RUN_PATH}/db_exp_full.log
i dont want the log either on the screen or the log file.I will just scan the log file for errors ,if any, mentioned in the log parameter of imp above.
Any ideas?

poet::import
Poet::Import(3pm) User Contributed Perl Documentation Poet::Import(3pm)
NAME
Poet::Import -- Import Poet quick vars and utilities
SYNOPSIS
# In a script...
use Poet::Script qw($conf $poet $log :file);
# In a module...
use Poet qw($conf $poet $log :file);
DESCRIPTION
Poet makes it easy to import certain variables (known as "quick vars") and utility sets into any script or module in your environment.
In a script:
use Poet::Script qw(...);
and in a module:
use Poet qw(...);
where "..." contains one or more quick var names (e.g. $conf, $poet) and/or utility tags (e.g. ":file", ":web").
(Note that "use Poet::Script" is also necessary for initializing the environment, even if you don't care to import anything, whereas "use
Poet" has no effect other than importing.)
QUICK VARS
Here is the built-in list of quick vars you can import. Some of the variables are singletons, and some of them are specific to each package
they are imported into.
$poet
The global environment object, provided by Poet::Environment. This provides information such as the root directory and paths to
subdirectories.
For backward compatibility this is also available as $env.
$conf
The global configuration object, provided by Poet::Conf.
$cache
The cache for the current package, provided by Poet::Cache.
$log
The logger for the current package, provided by Poet::Log.
UTILITIES
Default utilities
The utilities in Poet::Util::Debug are always imported, with no tag necessary.
:file
This tag imports all the utilities in Poet::Util::File.
:web
This tag imports all the utilities in Poet::Util::Web. It is automatically included in all Mason components.
MASON COMPONENTS
Every Mason component automatically gets this on top:
use Poet qw($conf $poet :web);
"$m->cache" and "$m->log" will get you the cache and log objects for a particular Mason component.
CUSTOMIZING
Adding variables
To add your own variable, define a method called provide_var_varname in "MyApp::Import". For example to add a variable $dbh:
package MyApp::Import;
use Poet::Moose;
extends 'Poet::Import';
method provide_var_dbh ($caller) {
# Generate and return a dbh.
# $caller is the package importing the variable.
# $poet is the current Poet environment.
}
"provide_dbh" can return a single global value, or a dynamic value depending on $caller.
Now your scripts and libraries can do
use Poet::Script qw($dbh);
use Poet qw($dbh);
Adding utility tags
To add your own utility tag, define a class "MyApp::Util::Mytagname" that exports a set of functions via the ':all' tag. For example:
package MyApp::Util::Hash;
use Hash::Util qw(hash_seed all_keys);
use Hash::MoreUtils qw(slice slice_def slice_exists);
our @EXPORT_OK = qw(hash_seed all_keys slice slice_def slice_exists);
our %EXPORT_TAGS = ( 'all' => @EXPORT_OK );
1;
Now your scripts and libraries can do
use Poet::Script qw(:hash);
use Poet qw(:hash);
