Hey All,

I've got a meeting tomorrow and need to know some basic unix / linux commands. (mainly Red Hat Enterprise Linux)

I know more or less most of them, like grep, less, more, vi, cp, ls, mv, rm.


anyone have some tips or other commands I can learn and play around with to be prepared for tomorrow?


Thanks in advance.

Here you go:

(assuming you're using the bash shell as Red Hat user)

Will also post entire useful for everyday command lines when i get home from work.

su

That's the king of commands

Heres a little list.

su - change to root
cd (dir path) change directory
chown (change ownership)
mv ( mv )
chmod (set file permissions)
awk
w (shows whos currently on the server)
last (shows last logins)
netstat -ntlp (shows what processes are listening)
ps awux shows processes
top shows processes
sar -r (memory load history) -u processor load
free -m
fdisk -l lists disks in server
lsusb
rpm -qa shows currently installed apps on redhat based system
| grep after a command can search

example
ps awux | grep httpd will show the apache processes

pstree

you can | grep processes to see how many are in the process tree

kill -9 Process id will kill the id
reboot (reboots server)
useradd adds user
groupadd adds group
userdel deletes user
crontab -e edits crontab

Lots more, list can go on.

That should get you started.
