Java output from crontab run

Hi,

I am trying to schedule a job in linux through the crontab command.My script actually does some text processing and echoes some output.My cron scheduler is working fine,but the output messages(echoes from script) is mailed to my mail account(in unix -/var/local/mail).Is it not possible to view the output messages in the screen rather than redirecting it into a file?

I am working on a remote Suse Linux 9.0 server.
Your help is appreciated.

With Regards
Dileep Pattayath

NAME
crontab - user job file scheduler SYNOPSIS
[file] [username] [username] [username] DESCRIPTION
The command manages a crontab file for the user. You can use a crontab file to schedule jobs that are executed automatically by (see cron(1M)) on a regular basis. The command has four forms: Create or replace your crontab file by copying the specified file, or standard input if file is omitted or is specified as file, into the crontab directory, The name of your crontab file in the crontab directory is the same as your effective user name. If the compartmentalization feature is enabled, the crontab file is your effective user name followed by a colon followed by the compartment id from which the crontab file is created. Edit a copy of the user's crontab file, or create an empty file to edit if the crontab file does not exist. When editing is complete, the file will be copied into the crontab directory as the user's crontab file. If the compartmentalization feature is enabled, it only edits a copy of the user's crontab file from the compartment that the crontab files were created from. Lists the user's crontab file. If the compartmentalization feature is enabled, it only lists the crontab files from the compartment that the crontab files were created from. Remove the user's crontab file from the crontab directory. If the compartmentalization feature is enabled, it only removes the crontab files from the compartment that the crontab files were created from. Only a privileged user can use username following the or options, to edit, list, or remove the crontab file of the specified user. The entries in a crontab file are lines of six fields each. The fields are separated by spaces or tabs. The lines have the following for- mat: minute hour monthday month weekday command The first five are integer patterns that specify when the sixth field, command, should be executed. They can have the following ranges of values: minute The minute of the hour, hour The hour of the day, monthday The day of the month, month The month of the year, weekday The day of the week, Each pattern can be either an asterisk meaning all legal values, or a list of elements separated by commas. An element is either a number in the ranges shown above, or two numbers in the range separated by a hyphen (meaning an inclusive range). Note that the specification of days can be made in two fields: monthday and weekday. If both are specified in an entry, they are cumulative. For example, runs command at midnight on the first and fifteenth of each month, as well as every Monday. To specify days in only one field, set the other field to asterisk For example, runs command only on Mondays. The sixth field, command (the balance of a line including blanks in a crontab file), is a string that is executed by the shell at the spec- ified times. A percent character in this field (unless escaped by a backslash is translated to a newline character, dividing the field into "lines". Only the first "line" (up to a or end-of-line) of the command field is executed by the shell. Any other "lines" are made available to the command as standard input. Blank lines and those whose first non-blank character is will be ignored. invokes the command from the user's directory with the POSIX shell, It runs in the queue (see queuedefs(4)). supplies a default environment for every shell, defining: Users who desire to have their executed must explicitly do so in the crontab entry or in a script called by the entry. You can execute if your name appears in the file If that file does not exist, you can use if your name does not appear in the file If only exists and is empty, all users can use If neither file exists, only the user can use The files consist of one user name per line. Security Restrictions If the compartmentalization feature is enabled, and invoke the jobs from the compartment that the jobs were created from. Note that cre- ates the job files in Hence, if the command is invoked from a compartment which has no write access to this directory and which disallows the privilege, fails to schedule the jobs. See compartments(5) and privileges(5) for more information. EXTERNAL INFLUENCES
