I have some bash scripts which I manually run a lot and they need to run with sudo. I also don’t want to be prompted for any password. Here is the solution.

1. Edit the /etc/sudoers:

   [code language=”bash”]$ sudo vi /etc/sudoers[/code]

2. Add a new entry at the last (USERNAME is your account name).

   [code language=”text” firstline=”18″ highlight=”26″]
   # User privilege specification
   root ALL=(ALL:ALL) ALL

   # Members of the admin group may gain root privileges
   %admin ALL=(ALL) ALL

   # Allow members of group sudo to execute any command
   %sudo ALL=(ALL:ALL) ALL
   USERNAME ALL=(ALL:ALL) NOPASSWD:ALL

   # See sudoers(5) for more information on "#include" directives:

   #includedir /etc/sudoers.d
   [/code]

3. Restart the sudo service.

   [code language=”bash”]$ sudo service sudo restart[/code]

4. Logout then login again. You won’t be prompted for the password anymore.

It’s very easy after googling…

$ cd /usr/share/applications
$ sudo cp LotusNotes8.5.desktop LotusNotes8.5-url.desktop
$ sudo vi LotusNotes8.5-url.desktop

The example:

[Desktop Entry]
Encoding=UTF-8
Name=Lotus Notes 8.5 Url
Type=Application
Exec=/opt/ibm/lotus/notes/framework/../notes-wrapper %u
Icon=/opt/ibm/lotus/notes/framework/shared/eclipse/features/com.ibm.notes.links.feature_8.5.4.20120906-1255/icons/notes.ico
Terminal=false
MimeType=x-scheme-handler/notes

$ sudo update-desktop-database

We have some python scripts for scheduled jobs. They are moved from a old machine and work very well automatically and manually. When we moved them to another machine, manually run them works fine. But they don’t work when we put them in corn.

After some search, there are two python versions in system. One is in /usr/bin and another one is in /usr/local/bin. Hmmm… That’s $PATH problem!

In bash shell, when we run the scripts manually, they are run by /usr/local/bin/python.

In cron, they are run by /usr/bin/python. Unfortunately, this version is too old to be compatible with our scripts.

   cp -r eclipse /opt/eclipse_kepler
   [/code]
5. Create a desktop file and install it.
   [code language=”bash”]
   gedit eclipse_kepler.desktop
   [/code]
   The content of eclipse_kepler.desktop:
   [code]

If you create some local user accounts in Windows for providing some services, but don’t want to let them show in Welcome Screen. You can add some settings in Windows Registry.

[code language=”text”]Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
"cyg_server"=dword:00000000

[/code]

I have tried this in Windows 7 and Windows 2008 R2. It works.
