* Learn how to use redirection ("<tt><</tt>", "<tt>></tt>") and pipes ("<tt>|</tt>") in the [Shell]. See bash(1)
* Your initial WindowManager settings are (generally) stored in the <tt>.xinitrc</tt> or <tt>.xsession</tt> file in your home.
** Note that this isn't so relevant any more with GNOME and KDE
+
+!!Handy Ubuntu Tips
+
+!Write a bash script.
+Open up your favourite text editor and add this line to the top:
+*~#~!/bin/bash
+Now add your bash commands and at end of each line add a ";"
+Save you file and make sure you chmod to give execute permissions.
+
+!Extract zips that are in multiple parts.
+*unzip -d destdir/ \~*.zip
+
+REMEMBER : The '\' is the escape character. Without it, our command would look like:
+unzip -d destdir/ 1.zip, 2.zip, 3.zip which is bad because after the first zip argument, the following stuff is read as list arguments. With \~*.zip bash doesn't interpret the ~* but unzip does.
+
+!Extract rars that are in multiple parts (Using Rar Linux) (eg: .rar,.ro1,r02...)
+*unrar name.rar destdir/
+Note: We only need to supply the file with the ".rar" extension. Rar is smart and detects the other files.
+
+!Cool tools to play around with
+*cal
+Typing this command will display a calendar with the date highlighted.
+*date
+Will display the date and time in terminal.
+*dmesg
+Displays log of messages printed to the screen during the boot process
+
+!Where on Earth is the rename command?
+We use the "mv" command when renaming instead.
+*mv dog cat
+This will rename the file "dog" to "cat".
+
+!You can copy/move/list multiple things at a time! Just separate files/expressions with a space.
+*ls -l *.txt *.letter
+*cp *.jpg *.bmp ~~/pics/
+
+!How to Stop listing dir contents when using glob expressions with ls.
+Use the -d switch to list just the directories, and not the contents of each matching directory.
+
+!Change Password
+Simply type "passwd". You will be prompted for the current password and then asked to type in a new password.
+
+!Jump quickly between words in terminal
+*Alt-f - Move forward one word.
+*Alt-b - Move backward one word.
+
+!Print to screen first/last few lines of a file.
+*head -n 20 test.txt
+Will print to the screen the first 20 lines in test.txt
+*tail -n 5 test.txt
+Will print to the screen the last 5 lines in test.txt
+
+!Print a Message To The Terminal
+*echo Damn you rock Staz
+Note : Make sure to type the above exactly as it is written.
+*echo $PATH
+Slightly more useful!
+
+!Display a long file to screen
+*more test.txt
+Will print the first page of test.txt to the screen, and you can use arrow keys to navigate further.
+*less test.txt
+A more advanced version of more. (Can do Searches etc).
+
+!Search command History
+*Alt-r
+Now Start typing part of the command any matches will be displayed as you type and press enter to use them.
+
+!What type of file is that??
+*file <filename>
+Will return the file type.
+
+!Reload fstab file
+*sudo mount -a
+This mounts everything in your fstab file.
+
+!How much disk space is the contents of this directory using?
+
+1)All Folders/Subfolders
+*du -h
+2)The current directory
+*du -sh
+3)All folders excluding subfolders.
+*du --max-depth=1 -h
+4)All folders beginning with the letter P
+*du -sh P*
+
+!Mount Samba Shares
+We need to get the smbfs and smbclient packages.
+* sudo aptitude install smbfs
+* sudo aptitude install smbclient
+
+First lets get a list of the available shares on a particular machine.
+*smbclient -L <IP/HOST>
+
+Now create a folder in /media/ that will be the mount point for your samba share.
+There are two ways of mounting:
+1.
+*sudo smbmount //<IP/Hostname>/smbshare /media/mounthere/ -o username=YYYY,password=YYYY,dmask=XXX,fmask=XXX
+2.
+*sudo mount -t smbfs //<IP/Hostname>/smbshare /media/mounthere/ -o username=YYYY,password=YYYY,dmask=XXX,fmask=XXX
+
+dmask = directory umask
+fmask = file umask
+
+Now to unmount:
+*sudo umount/smbumount /media/diryoumountedto/
+
+!Add a smb share to fstab that is automatically mounted on boot
+*sudo /etc/fstab
+Add this line:
+//HOST/share/ /mount/point/ smbfs auto,username=xxxxx,password=xxxxx,uid=xxxx
+This website is really good:
+http://doc.gwos.org/index.php/HowToMountsmbfsSharesPermanently
+
+!Mount all smb shares listed in fstab
+*sudo mount -at smbfs
+
+!Unmount all smb shares listed in fstab
+*sudo mount -at smbfs
+
+!List NTFS Mounted Drives
+* sudo mount -t ntfs
+If you want to view mounted fat32 drives simply replace "ntfs" with "vfat"
+
+!How much memory is free?
+* free -m
+Will tell you how much free memory is available in megabytes.
+*free -s 60
+Will tell you how much free memory is available every 10 seconds.
+
+!List all your drives
+* sudo fdisk -l
+NOTE : Don't forget the "sudo" or else you may not see anything listed.
+Blocks can be read to mean "Kilobytes"
+
+!List Drives/Capacity/Free Space
+*df -B M
+The -B switch refers to Block Size. The M means it will be displayed in Megabytes.
+But if you prefer use K for kilobytes, G for gigabytes etc..
+
+df(1) doesn't require root privileges to work. Also "df -h" will select the right units for you. Many programs that support outputting units will support "-h" for "human readable". The other useful command here is du(1).
+
+!Install an app from .rpm
+First you need Alien:
+sudo aptitude install al
