Notes for and by me.
The file /etc/inittab will open. Within the first screen, you'll see a section of the file which looks like this:
# Default runlevel. The runlevels used by RHS are: # 0 - halt (Do NOT set initdefault to this) # 1 - Single user mode # 2 - Multiuser, without NFS (The same as 3, if you do not have networking) # 3 - Full multiuser mode # 4 - unused # 5 - X11 # 6 - reboot (Do NOT set initdefault to this) # id:3:initdefault: |
To change from a console to a graphical login, you should change the number in the line id:3:initdefault: from a 3 to a 5.
Killing Processes: /etc/rc.d/init.d has startup
and stop scripts (for RedHat). Or kill pid.
What's Running: use ps -aux to list all the running processes. ps
pid where pid is the Process ID (found using the previous
command, you get additional useless info).
Problems?: See the /var/log/messages file. Use tail -n XX /var/log/messages to see the last XX lines of the logfile. I've also setup an alias command for logtail and loghead for 25 lines each.
You can type help, but it seems to be generally useless. You gotta know the commands.
ls -al: like dir on DOS.
man - the manual pages
tail -n XX filename - the last XX lines of a file. main log is stored at /var/log
head -- same as tail but beginning
ps -A to see all processes.
kill XXX - to kill a process. to get a process ID (XXX), look in /var/run
