The first thing you will want to do is specify the download folder. To do that, click Settings button.

Use mintStick in Linux Mint.

mintStick is installed by default in Linux Mint.
Launch "USB Image Writer" from the menu, select your ISO image and your USB device and press "Write to device".

Using the Terminal

It is really simple. Go to a Terminal and type:

sudo dd if=~/Desktop/linuxmint.iso of=/dev/sdx oflag=direct bs=1048576

Where '~/Desktop/linuxmint.iso' is the name and location of your downloaded image (located at the desktop in this example) and '/dev/sdx' is the target USB drive. If your system doesn't support 'oflag=direct', you can just leave it out as it is simply intended to speed up the process a bit.

If you don't know about the target USB drive path, run this command and figure out your destination drive.

sudo fdisk -l

Warning: Make sure to set the correct device path, as this process will delete all data that was on the specified device previously!

Remember, don't include an integer for the USB drive, e.g. '/dev/sdx1', as it would refer to the existing partition on that drive and not the drive itself.

When the USB has been properly created by 'dd', there should be an output similar to this:

sudo dd if=~/Desktop/linuxmint.iso of=/dev/sdb oflag=direct bs=1048576
706+1 records in
706+1 records out

How to change the GRUB 2 Default Timeout and Boot Order

GRUB 2 is the next generation of GNU GRUB, using version numbers 1.90 and above. GRUB 2 is a complete rewrite. The most important goal is to make GNU GRUB cleaner, safer, more robust, more portable and more powerful.

If you're already familiar with GRUB Legacy, you'll find that the GRUB 2 configuration file is similar in broad strokes, but it varies in many details. You should be aware of alternative means of configuring GRUB 2, as well.

To make any changes the way GRUB 2 works you need to edit the main GRUB 2 configuration file located in /etc/default/ folder, you can edit it by running the following command from terminal:
sudo gedit /etc/default/grub you should see the content very similar to this ....

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=7
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Change default Timeout:
To change the default timeout option in GRUB 2, you just need to change the GRUB_TIMEOUT parameter. The value of this parameter is in sec, change this value as per your requirement.

Change the default boot option:
To change the default boot option in GRUB 2, you just need to change the GRUB_DEFAULT parameter. 0 is the first entry, so if you want Windows to be your default boot option which is, say at, 5th position in the grub menu, then you just need to change the GRUB_DEFAULT value to 4 and save the file and close it. Save the file after making all the required changes and from the terminal run the following command

sudo update-grub

Change Apache ports Ubuntu

How to change apache2 ports

Open up a Terminal and run the following command.

#sudo pico /etc/apache2/ports.conf

Now, inside this file you should see something like the following:

NameVirtualHost *:80
 Listen 80

If you want to change the default apache port completely simply change “Listen 80″ to what you need, for example “Listen 1337″. If you want to add another port while keeping port 80 open, you can simply add another line for example:

NameVirtualHost *:80
 Listen 80
 Listen 1337

Then edit default file

#sudo pico /etc/apache2/sites-available/default
and change <VirtualHost *:80> to the new port

Last thing you have to do now is restart Apache.

#sudo /etc/init.d/apache2 restart

SSH to Unix/Linux with another port number

Connect to OpenSSH Server with different port number

#ssh user@hostname -p9999

SYNOPSIS
ssh [-l login_name ] hostname | user@hostname [command ]

ssh [-afgknqstvxACNTX1246 ] [-b bind_address ] [-c cipher_spec ] [-e escape_char ] [-i identity_file ] [-l login_name ] [-m mac_spec ] [-o option ] [-p port ] [-F configfile ] [-L port host hostport ] [-R port host hostport ] [-D port ] hostname | user@hostname [command ]

Example:

#ssh john@10.1.1.1 -p1234
