Why can't you do it?

You may not be authorized to use cron. Or; you may be editing your crontab with ed if your VISUAL environment variable is not set.

You shouldn't edit the crontab directly like that.

From man crontab

Code:

           Note that all crontab jobs should be
           submitted using crontab; you should not  add  jobs  by
           just editing the crontab file because cron will not be
           aware of changes made this way.

Cheers

Continuing with man crontab:

Code:

SYNOPSIS
     crontab [ filename ]
     crontab [-elr] username

And

Code:

crontab Access Control
     Users: Access to crontab is allowed:

        o if the user's name appears in /etc/cron.d/cron.allow.

        o if /etc/cron.d/cron.allow does not exist and the user's
          name is not in /etc/cron.d/cron.deny.

     Users: Access to crontab is denied:

        o if /etc/cron.d/cron.allow exists and the user's name is
          not in it.

        o if /etc/cron.d/cron.allow does  not  exist  and  user's
          name is in /etc/cron.d/cron.deny.

        o if neither file exists.

     Note that the rules for allow and deny apply to root only if
     the allow/deny files exist.

     The allow/deny files consist of one user name per line.

So, have a look at the files located in /etc/cron.d

"crontab -e" should work...

And as zazzybob says, you should not edit crontabs by hand...

About your cron job, what do you want such a job for? Anyway its syntax is OK...

Regards.

Is it possible you dont have your EDITOR environment variable set and so when you issue the 'crontab -e' command on solaris you just get a ':' prompt?

If so try:

Code:

EDITOR=vi
export EDITOR
crontab -e
