Recently i had formatted my machine and had installed Linux on it. I don't know much about Linux, but i'm very much familiar with HTML. Even i don't know anything when it comes to knowing what "sh" Script means. I would like to know that how to run LINUX Script or command on my pc? Is there any free online/offline tutorial for LINUX Scripts and Commands? Any body have any idea about it? Please provide me the correct information on the above topic.
When in the command line, you are using a ''shell'' – most likely the bash shell. Use the man command (% man) to see how a command is used on your particular computer. agetty opens a tty port, prompts for a login name and invokes the /bin/login command.
Before you can use the system, you must identify yourself by logging in. The install program created a special user named root; by identifying yourself as the root user, you can gain access to the system. In a shell you can define a variable and set a value to it to be retrieved later. Here is an example of a variable named ORACLE_HOME:
Later, you can refer to the variable by prefixing a ''$'' sign to the variable name, e.g.:Quote:
# export ORACLE_HOME=/opt/oracle/product/11gR2/db1
This is called a user defined variable. Likewise, there are several variables defined in the shell itself.Quote:
# cd $ORACLE_HOME
When you use a command in Linux, it's either in a shell as you saw with the kill command in Part 4 or it's an executable file. Like other members of the Unix family, the Linux operating system is case sensitive. Be sure to type the userid root just as it appears, using all lowercase characters. If it's an executable, how do you know where is it located? Also, some Linux programs require you to type Ctrl-BACKSPACE, rather than BACKSPACE. If you press BACKSPACE and see ^H echoed to the console, try pressing Ctrl-BACKSPACE instead. Similarly, you must type the password exactly as you entered it in the Root Password dialog box during system installation.
