By default base directory for the system user is set to /home directory. I’d like to add user to /iscsi/home/${user} directory instead of the default /home. How do I force useradd command to add user to /iscsi/home under CentOS / RHEL / Fedora Linux server?
Default values for account creation defined in /etc/default/useradd file under CentOS / RHEL / Fedora / Debian / Ubuntu and other Linux distros. Simply open this file using a text editor, type:
# vi /etc/default/useradd
The default home directory defined by HOME variable, find line that read as follows:
HOME=/home
Replace with:
HOME=/iscsi/user
Save and close the file. Now you can add user using regular useradd command:
# useradd vivek
# passwd vivek

Verify user information:
# finger vivek
Output:

How Do I Change Existing User’s Home Directory?

Dev C User Default Directory Password

You need to use the usermod command to set the user’s new login directory. The syntax is as follows:

1. -d dirnanme : Path to new login (home) directory.
2. -m : The contents of the current home directory will be moved to the new home directory, which is created if it does not already exist.

In this example set the user’s new login directory to /users/v/vivek from /home/vivek, enter:
# usermod -m -d /users/v/vivek vivek

Arduino Libraries

Libraries are files written in C or C++ (.c, .cpp) which provide your sketches with extra functionality (e.g. the ability to control an LED matrix, or read an encoder, etc.). They were introduced in Arduino 0004.

To use an existing library in a sketch simply go to the Sketch menu, choose 'Import Library', and pick from the libraries available. This will insert an #include statement at the top of the sketch for each header (.h) file in the library's folder. These statements make the public functions and constants defined by the library available to your sketch. They also signal the Arduino environment to link that library's code with your sketch when it is compiled or uploaded.

User-created libraries as of version 0017 go in a subdirectory of your default sketch directory. For example, on OSX, the new directory would be ~/Documents/Arduino/libraries/. On Windows, it would be My DocumentsArduinolibraries. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch Import Library menu in the Arduino IDE.

Note: for users of versions previous to 0017, libraries belong in a subdirectory of the Arduino application directory: ARDUINO/lib/targets/libraries. For version 0017, the libraries directory was moved to make them more convenient to install and use.

Dev C User Default Directory List

Because libraries are uploaded to the board with your sketch, they increase the amount of space used by the ATmega8 on the board. See the FAQ for an explanation of various memory limitations and tips on reducing program size. If a sketch no longer needs a library, simply delete its #include statements from the top of your code. This will stop the Arduino IDE from linking the library with your sketch and decrease the amount of space used on the Arduino board.

Dev C User Default Directory Search

To get started writing libraries, download this test library. It should provide a basic template for creating a new library. After you've made changes to your library, in order to get it to recompile, you will have to delete the .o file generated in the library's directory.
