NAME

       smcron - manage jobs in the crontab database

SYNOPSIS

       /usr/sadm/bin/smcron  subcommand [ auth_args]  -- [subcommand_args]

DESCRIPTION

       The smcron command manages jobs in the crontab(1) database.

   subcommands
       smcron subcommands are:

       add	       Adds  a	job  to the crontab(1) database. To add a job, the administrator must have the solaris.jobs.user authorization. To
		       add a job to another user's crontab file, the administrator must have the solaris.jobs.admin authorization.

       delete	       Deletes a job from the crontab(1) database. To delete a job, the administrator must have the  solaris.jobs.user	authoriza-
		       tion. To delete a job from another user's crontab file, the administrator must have the solaris.jobs.admin authorization.

       list	       Lists  one  or  more  jobs  in the crontab(1) database. To list all jobs, the administrator must have the solaris.jobs.user
		       authorization. To list a job in another user's crontab file, the administrator must have the solaris.jobs.admin	authoriza-
		       tion. No authorization is needed to list a user's own jobs.

       modify	       Modifies  a  job  in the crontab(1) database. To modify a job, the administrator must have the solaris.jobs.user authoriza-
		       tion. To modify a job in another user's crontab file, the administrator must have the solaris.jobs.admin authorization.

OPTIONS

       The smcron authentication arguments, auth_args, are derived from the smc(1M) arg set and are the same regardless of  which  subcommand  you
       use.   The smcron command requires the Solaris Management Console to be initialized for the command to succeed (see smc(1M)). After reboot-
       ing the Solaris Management Console server, the first Solaris Management Console connection might time out, so you might need to	retry  the
       command.

       The subcommand-specific options, subcommand_args, must come after the auth_args and must be separated from them by the -- option.

   auth_args
       The  valid auth_args are -D, -H, -l, -p, -r, and -u; they are all optional. If no auth_args are specified, certain defaults will be assumed
       and the user may be prompted for additional information, such as a password for authentication purposes. These letter options can  also	be
       specified  by their equivalent option words preceded by a double dash. For example, you can use either -D or --domain with the domain argu-
       ment.

       -D | --domain  domain

	   Specifies the default domain that you want to manage. smcron accepts only file for this option. file is also the default value.

	   The file default domain means that changes are local to the server. Toolboxes can change the  domain  on  a	tool-by-tool  basis;  this
	   option specifies the domain for all other tools.

       -H | --hostname	host_name:port

	   Specifies  the  host_name and port to which you want to connect. If you do not specify a port, the system connects to the default port,
	   898. If you do not specify host_name:port, the Solaris Management Console connects to the local host on port 898. You may still have to
	   choose  a  toolbox  to load into the console.  To override this behavior, use the smc(1M) -B option, or set your console preferences to
	   load a "home toolbox" by default.

       -l | --rolepassword  role_password

	   Specifies the password for the role_name. If you specify a role_name but do not specify a role_password, the system prompts you to sup-
	   ply	a  role_password.  Passwords  specified on the command line can be seen by any user on the system, hence this option is considered
	   insecure.

       -p | --password	password

	   Specifies the password for the user_name. If you do not specify a password, the system prompts you for one. Passwords specified on  the
	   command line can be seen by any user on the system, hence this option is considered insecure.

       -r | --rolename	role_name

	   Specifies a role name for authentication. If you do not specify this option, no role is assumed.

       -u | --username	user_name

	   Specifies  the  user  name  for  authentication.  If  you  do not specify this option, the user identity running the console process is
	   assumed.

       --

	   This option is required and must always follow the preceding options. If you do not enter the preceding options, you must  still  enter
	   the -- option.

   subcommand_args
       For  the  time-related  subcommands described below, -m, -M, -t, and -w, you can enter multiple arguments, separated only by commas. smcron
       will construct crontab entries appropriate for your arguments.  See EXAMPLES.

       Note: Descriptions and other arg options that contain white spaces must be enclosed in double quotes.

		week  at the time specified by -t. If you specify both -t and -m options, the job executes one day per month at the time specified
		by -t. If you specify both -t and -M options, the job executes each day during the specified month at the time specified by -t.

EXAMPLES

       Example 1: Adding a Job

       The following adds a new job, owned by root, that removes the old log files from /tmp daily at 1:30 AM.

       ./smcron add -H myhost -u root -p mypassword -- -n "Remove old logs" 
		    -t 1:30 -c "rm /tmp/*.log" -o root

       Example 2: Deleting a Job

       The following deletes the job Remove old logs owned by root:

       ./smcron delete -H myhost -u root -p mypassword -- 
		 -n "Remove old logs" -o root

       Example 3: Listing Jobs in Native Format

       The following lists all jobs in native, or crontab(1), format:

       ./smcron list -H myhost -u root -p mypassword -- -f n
       MINUTE HOUR DATE MONTH DAY COMMAND

       30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean

       Example 4: Listing Jobs in Standard Format

       The following lists all jobs owned by lp in standard format:

       ./smcron list -H myhost -u root -p mypassword -- -f s -o lp
       NAME::OWNER::SCHEDULE::COMMAND

       NoName_1765663371::lp::Weekly on Sundays at 3:13 AM::cd /var/lp/logs;

       NoName_512822673::lp::Weekly on Sundays at 4:15 AM::cd /var/lp/logs;
	  if [ -f lpsched ]; then if [ -f lpsched.1 ]; then /bin/mv lpsched.1
	  lpsched.2; fi; /usr/bin/cp lpsched lpsched.1; >lpsched; fi

       Example 5: Listing jobs in verbose format

       The following lists all jobs in verbose format:

       ./smcron list -H myhost -u root -p mypassword -- -f v
       NAME::OWNER::SCHEDULE::NEXT_RUN::STATUS::COMMAND

       Example 6: Changing a Job

       The following modifies the job Remove old logs owned by root to execute daily at 2:00 AM:

       ./smcron modify -H myhost -u root -p mypassword -- -n "Remove old logs" 
		 -o root -t 2:00

       Example 7: Specifying Multiple Time Arguments

       smcron  allows you to specify a range of times for all of its time-related subcommands, -m, -M, -t, and -w. For example, the following com-
       mand:

       # smcron add -u root -p xxxx -- -n cronjob1 -w 1-4,5 
       -t 12:00,13:15,14:30 -c ls

       ...creates the following entry in crontab:

       0,15,30 12,13,14 * * 1,2,3,4,6 ls #cronjob1

       This job would run on Monday through Thursday and Saturday at the following times:

       12:00 12:15 12:30
       13:00 13:15 13:30
       14:00 14:15 14:30

ENVIRONMENT VARIABLES

       See environ(5) for a description of the JAVA_HOME environment variable, which affects the execution of the smcron command.  If  this  envi-
       ronment variable is not specified, the /usr/java location is used. See smc(1M).

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       1	Invalid command syntax. A usage message displays.

       2	An error occurred while executing the command. An error message displays.

NOTES

       The  timezone  of  the  cron  daemon  sets the system-wide timezone for cron entries. This, in turn, is by set by default system-wide using
       /etc/default/init.

       If some form of daylight savings or summer/winter time is in effect, then jobs scheduled during the switchover  period  could  be  executed
       once, twice, or not at all.
