thats it.

change hostname in solaris 10 after fresh install.

1. backup the /etc/hosts and /etc/hostname.interface files.
2. add the hostname entry in the /etc/hosts file.
3. mv the old /etc/hostname.interface to /etc/new_hostname.interface
4. on the command line hostname hostname
 exit from the terminal and login back. You should see the new hostname now.

Change the PS1 value for the login prompt:

PS1="\u@\h: \W $ "

Crontab in solaris 10

A little different in solaris 10 while editing the cron job.

You will have to export the vi editor and then edit the crontab file.

   #  EDITOR=vi
   # export EDITOR
   # crontab -e

#ident  "@(#)root       1.21    04/03/23 SMI"
#
# The root crontab should be used to perform accounting data collection.
#
#
10 3 * * * /usr/sbin/logadm
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
#
# The rtc command is run to adjust the real time clock if and when
# daylight savings time changes.
#
1 2 * * * [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1
#10 3 * * * /usr/lib/krb5/kprop_script ___slave_kdcs___
0 22 21,10 * * "Testing crontab" > /dev/console

 wq! and the save the file

-bash-3.2# crontab -l
