1. Lets create the command file.
Open Terminal (Applications -> Utilities -> Terminal) then create the file in your home directory by running the following

pico filename.command [enter]

Once in type in your script to become a executable command and hold CTRL and press O then CTRL and X to exit your pico window.
Remember to put #!/bin/bash at the beginning to prevent output from your command.

2. Now lets turn this file into an executable.
ok we will CHMOD the command file to enable execution of the file. run the following

chmod +x filename.command [enter]

Job done! your file is now executable.

3. Here is the optional final step to make this launch from a user logging in on mac.

Go to System Preferences > Accounts > Select the account > Login Items

Then you can either drag and drop your command file into the login items OR you can click the + and navigate to the file that way.

• Start by holding the Windows Key (between ALT and CTRL) and pressing R
  This will open the RUN window.
• In the RUN window that opens type the following.

control userpasswords2

Then press OK or enter. see image below(screen shot from Server 2008).



• Following That you will be presented with the below menu. Uncheck the box shown below that says ‘Users must enter a user name and password to use this computer.’ and then click Apply
  
  
• After clicking Apply you will be given a login box, as seen below, where you can enter the login credentials that will be used upon startup to auto log the machine in.
  Select OK and OK out of the “userpasswords2″ User Accounts window and test your new configuration.

I’d like to point out that this is not a very secure function and I would recommend against it, however in some circumstances it is a requirement and for that reason I’ve done this short post.

Any questions, leave them in the comments. Cheers

So lets begin.

1. Open Terminal and gain elevated privileges
   Click on Applications >> Utilities >> Terminal then enter the below command to gain elevated privileges.

   sudo su

   you will need to provide your root password at the prompt see below, typing the password will be blind.
   

2. Enter and edit the hosts file as below.
   Enter the below command to edit the hosts file

   pico /etc/hosts

   Once in pico you will see something like the below screen shot.
   

3. Once done save!
   Once you’ve finished editing the file as required hold Control and hit O then Enter, then Control and hit X to exit, and you’re done! Exit Terminal.

Job done! It isn’t difficult, however you need to use the sudo su command to gain root privileges before you will be able to successfully save the hosts file. For more information on Hosts Files check out this wiki link.

So in this little post I’ll be demonstrating how to use Terminal to mount an SMB (windows share) to a folder. Firstly there is the basic method of “Connect to Server” from the Finder >> Go >> Connect to Server option, see image left.. While I regularly use this method it simply mounts the share as a browse-able network share failing to actually “mount” it to a folder on your Mac drive. To briefly cover this Connect to Server option, simply select the connect to server option then type in smb://serveraddress/share and hit connect, its that simple.

My Mount option is a little more tricky however it enables the ability to say use a SMB share for all of your iTunes music, or work from a SMB/Windows share. Of great benefit is utilizing this as a logon script to enable a user in a predominantly Windows environment to have an equivalent to “mapped network drives” on their mac.

1. Open up Terminal and mount mount mount!
   Head to Applications >> Utilities >> Terminal and follow the below sample to create a folder to mount to in your home directory and to mount your share to said folder. Note you can create the folder wherever you want.

mkdir ./sharemount

The below will mount your smb share to the folder we just created!

mount_smbfs //username:password@serverip/share ./sharemount

Ensure that the user account you will use to access this share has the correct permissions on the share and the folder (inherited down) on the windows server or you will mount but have issues accessing files.

Unfortunately this method will only mount for the session and a restart will require the command to be run again (not the mkdir bit! just the mount_smbfs bit) I find the best way is to create a script and then have it launch when the user logs in.

NOTES: I’ve noticed some occasions where windows server might have restarted or the MAC went to sleep and didn’t re establish correctly, for this I usually simply eject the server in Finder by clicking the little eject button to the right of the server in finder and then run the script again to reconnect the shares. Perhaps even leave a copy of the connect script you create on the desktop so the user can re establish before calling support!
