UNIX language to run software commands

Add a dot and a slash in front of the name of the software program/

In the console:

The contents of vi:

include

int main(void)

Then save and exit.

Run gcc -o hello (if you don't specify the o option, it will be generated by default instead of hello).

You have the hello executable in your current directory.

Use. hello to execute it. ok

What Unix version are you?

If you have a C compiler on your machine, such as GCC, write your program to. c file, for example, then.

gcc -o test

And then .test can execute the compiled program.

Some compiled language such as GCC or XLC needs to be installed

1. cd command.

This is a very basic command, which is often used, it is used to switch the current directory, and its parameters are the path of the directory to be switched to, which can be absolute or relative.

2. ls command.

This is a very useful command for viewing files and directories.

3. grep command.

This command is often used to analyze a line of information, and if there is any information we need, the line is displayed, and it is usually used in conjunction with pipeline commands, which is used to filter the output of some commands, etc.

4. Find command.

find is a very powerful lookup-based command, which is relatively complex to use and has a lot of arguments.

Enter it in the directory where it is located. /

Put these into a file, then compile them with the gcc command, output them as default, and then use them. Execute that, and that's it.

This is very simple,It seems that the brother is a Linux master,Basically will not use the win system,If you have the source** case,Under the windows system,Double-click the vc++ software,Create a new project,Then select Win32 Console Application,Then there should be a saved hard disk path and enter the project name on the right,Then follow the prompts Next,Straight road is completed,Then click on the left file view Then create a new file in the folder you want to add and save it as. c, you can write your source ** in, and then find an exclamation mark, click on it, and compile and run, and a dos window pops up when it runs, and you can see the loss of the game. C++ is fully compatible with the C language, VC's corrupt kernel compilation environment, and can have APIs, that is, write window programs.

Compared to Linux, you can just click a button and save writing those commands. The others shouldn't make much difference.

The red exclamation mark is running, the VC compiles, connects, and executes the compilation, connection, and execution, all of which are separated, if the red exclamation mark is not running, it means that there is something wrong with the VC software itself. It is recommended that you try again.

I'll only use Linux, but Unix should be the same.

The first is the source file, the program is written, the save, and the suffix. c, let's say you save as a home user

Then compile,Unix is compiled with cc,If you install it,The command is cc home user

Then under the home user, a file is generated, and thenand you can execute it.

Directly executed in front:

export path="$path: JerryBlack Documents C Calculator".

To display Chinese, the original program file must be included.

At. Profile=Export path=$path folder you want to execute

C language compilation, Chinese garbled code can not see **, it is likely to be a compiler problem.
