Common SSH Commands

We’ve put together some of the more frequently used SSH commands or linux shell commands, and organized them by name so you can easily find a command, their description and how to use it. This guide will continue to be updated and should not be considered a complete list of SSH commands or linux shell commands, but commands, we found, often used. If you would like to add to this guide, please email us and let us know.

Common SSH Commands or Linux Shell Commands,
ls : list files/directories in a directory, comparable to dir in windows/dos.
ls -al : shows all files (including ones that start with a period), directories, and details attributes for each file.

cd : change directory · · cd /usr/local/apache : go to /usr/local/apache/ directory
cd ~ : go to your home directory
cd – : go to the last directory you were in
cd .. : go up a directory cat : print file contents to the screen

cat filename.txt : cat the contents of filename.txt to your screen

tail : like cat, but only reads the end of the file
tail /var/log/messages : see the last 20 (by default) lines of /var/log/messages
tail -f /var/log/messages : watch the file continuously, while it’s being updated
tail -200 /var/log/messages : print the last 200 lines of the file to the screen

more : like cat, but opens the file one screen at a time rather than all at once
more /etc/userdomains : browse through the userdomains file. hit to go to the next page, to quit

pico : friendly, easy to use file editor
pico /home/burst/public_html/index.html : edit the index page for the user’s website.

vi : another editor, tons of features, harder to use at first than pico
vi /home/burst/public_html/index.html : edit the index page for the user’s website.

grep : looks for patterns in files
grep root /etc/passwd : shows all matches of root in /etc/passwd
grep -v root /etc/passwd : shows all lines that do not match root

touch : create an empty file
touch /home/burst/public_html/404.html : create an empty file called 404.html in the directory /home/burst/public_html/

ln : create’s “links” between files and directories
ln -s /usr/local/apache/conf/httpd.conf /etc/httpd.conf : Now you can edit /etc/httpd.conf rather than the original. changes will affect the orginal, however you can delete the link and it will not delete the original.

rm : delete a file
rm filename.txt : deletes filename.txt, will more than likely ask if you really want to delete it
rm -f filename.txt : deletes filename.txt, will not ask for confirmation before deleting.
rm -rf tmp/ : recursively deletes the directory tmp, and all files in it, including subdirectories. BE VERY CAREFULL WITH THIS COMMAND!!!

last : shows who logged in and when
last -20 : shows only the last 20 logins
last -20 -a : shows last 20 logins, with the hostname in the last field

w : shows who is currently logged in and where they are logged in from.

netstat : shows all current network connections.
netstat -an : shows all connections to the server, the source and destination ips and ports.
netstat -rn : shows routing table for all ips bound to the server.

top : shows live system processes in a nice table, memory information, uptime and other useful info. This is excellent for managing your system processes, resources and ensure everything is working fine and your server isn’t bogged down.
top then type Shift + M to sort by memory usage or Shift + P to sort by CPU usage

ps: ps is short for process status, which is similar to the top command. It’s used to show currently running processes and their PID.
A process ID is a unique number that identifies a process, with that you can kill or terminate a running program on your server (see kill command).
ps U username : shows processes for a certain user
ps aux : shows all system processes
ps aux –forest : shows all system processes like the above but organizes in a hierarchy that’s very useful!

file : attempts to guess what type of file a file is by looking at it’s content.
file * : prints out a list of all files/directories in a directory

du : shows disk usage.
du -sh : shows a summary, in human-readble form, of total disk space used in the current directory, including subdirectories.
du -sh * : same thing, but for each file and directory. helpful when finding large files taking up space.

wc : word count
wc -l filename.txt : tells how many lines are in filename.txt

cp : copy a file
cp filename filename.backup : copies filename to filename.backup
cp -a /home/burst/new_design/* /home/burst/public_html/ : copies all files, retaining permissions form one directory to another.

kill: terminate a system process
kill -9 PID EG: kill -9 431
kill PID EG: kill 10550
Use top or ps ux to get system PIDs (Process IDs)

EG:
PID TTY TIME COMMAND
10550 pts/3 0:01 /bin/csh

10574 pts/4 0:02 /bin/csh

10590 pts/4 0:09 APP

Each line represents one process, with a process being loosely defined as a running instance of a program. The column headed PID (process ID) shows the assigned process numbers of the processes. The heading COMMAND shows the location of the executed process.

Putting commands together
Often you will find you need to use different commands on the same line. Here are some examples. Note that the | character is called a pipe, it takes date from one program and pipes it to another.
> means create a new file, overwriting any content already there.
>> means tp append data to a file, creating a newone if it doesn not already exist.
< send input from a file back into a command.

grep User /usr/local/apache/conf/httpd.conf |more
This will dump all lines that match User from the httpd.conf, then print the results to your screen one page at a time.

last -a > /root/lastlogins.tmp
This will print all the current login history to a file called lastlogins.tmp in /root/

tail -10000 /var/log/exim_mainlog |grep domain.com |more
This will grab the last 10,000 lines from /var/log/exim_mainlog, find all occurances of domain.com (the period represents ‘anything’,
– comment it out with a so it will be interpretted literally), then send it to your screen page by page.

netstat -an |grep :80 |wc -l
Show how many active connections there are to apache (httpd runs on port 80)

mysqladmin processlist |wc -l
Show how many current open connections there are to mysql

Ubuntu 8.04 LTD ( Hardy Heron ) Review

Three days agao I downloaded Hardy RC, Ubuntu 8.04 from Indonesian Mirror kambing ui. There were some types of ISO I could choose, the alternates and the desktops (live CD). Both were for x64 and x86 machines. I decided to download the desktop (live CD) iso x86 since my laptop is x86.
With the speed of my internet connecttion it took me two days to download the iso with interruption of internet connection ( the hub was turned off by a friend). Using wget, that was not a problem. I continued the download from where it reached the last time.
As soon as the download finished, I checked the iso using VirtualBox for error, in case there were corrupt files. The result was Ok and then I tried the live CD within the Virtual Machine. It ran flawlessly with RAM only 256M.
Not much difference in appearance compared to Gutsy. There are of course improvement in Hardy ( Check out in ubuntu.com.
I also tried Firefox in VirtualBox after setting the network (using NAT, automatically it used DHCP). At that time my machine (ubuntu Gutsy) connect to the internet by Wireless LAN Broadcom BCM943xx).
After checking for some time, then I burnt the iso into CD with K3B. I rebooted my computer and run the live CD.
As in VirtualBox, it worked flawlessly without problem. The booting is quiet fast in my laptop: HP 520 Intel Celeron 1.8, 1 G RAM, Intel 945 shared, 80 G Hardisk (SATA), LAN and WLAN (Broadcom 943xx). The desktop effects worked out of the box since the VGA was Intel 945, so I didn’t need to set it up manually).
But before the Gnome Display Manager came up there was a message that the system could’t find the firmware of my wireless card. So then in live CD, I tried to set it up using System – Administration – Hardware Drivers. It automatically download and install b43-fwcutter (replacing bcm43-fwcutter) and fetch the firmware. Previously, I had tried in Beta and it failed to download the firmware.
Done and tried to connect to my access point. I didn’t know why I wasn’t able to connect though the the network wirelessly.

Maybe because I was in Live CD. So I installed it to my laptop. The wizard as usual was very easy to follow. The most important thing was to pay attention to the partitioning. And it started to install…..
Waited for about 15 minutes and suddently the install process was disappeared. It vanished in the step pof installing boot loader.
Trying for the second time had no different result.
I checked /boot and there was no grub folder there.
Googling and trying to get around with the GRUB instalation. As I had already installed Hardy beta before, I had already had menu entry for Hardy. It stated vmlinux.img-2.6.24-12generic and initrd-2.6.24-12. Working on it for some time and got no result.
Finally, I found out that the kernel version of Hardy Beta and RC were different. RC used 24-16 not 24-12. ( I was wondering for some time because my GRUB complained not finding the file needed to boot.
So, in conclusion to my trial on Hardy RC is the failure of the liveCD install to install GRUB.

BCM43xx Ndiswrapper in Hardy

First before you start installing ndiswrapper you need to blacklist b43 modules by editing /etc/modprobe.d/blacklist
$ sudo gedit /etc/modprobe.d/blacklist
password:

then add:

blacklist b43 (you can put it under blacklist bcm43xx

save and quit gedit.

The second step is to install ndiswrapper
From Applications – Add/Remove
search for ndiswrapper

It will automatically install ndiswrapper with its dependency

Third: copy the bcmwl5.inf and bcmwl5.sys to your home folder and fire up terminal/konsole

change to the directory where you put the two files:
$ cd bcm43
$ sudo ndiswrapper -i bcmwl5.inf

check if the driver is installed by giving command:
$ sudo ndiswrapper -l
bcmwl5 : driver installed
device (14E4:4311) present (alternate driver: bcm43xx)

Fourth: Edit rc.local

$ sudo gedit /etc/rc.local
add the following lines:
rmmod ssb
rmmod ndiswrapper
modprobe ndiswrapper

Fifth : Reboot your computer and setup your wireless network
