Introduction to Creating Shell and C applet under Linux

1. Create a shell script file

Gedit hello_shell.sh # #创建文件

2.## #在文件内添加一下内容

#!/bin/bash

For ((i=0;i<10;i++));d o

echo "Hello Shell"

Done

Exit 0

3. Add executable permissions to a file

chmod 755 hello_shell.sh

4. Execute the Script

./hello_shell.sh

# # #创建一个C语言程序 "Hello World"

1.gedit HELLO_WORLD.C

2.# #添加一下内容

#include <stdio.h>

int main (void)

{

printf ("Hello world!\n");

return 0;

}

3. Use GCC to generate executables after saving

Gcc-o Hello_world HELLO_WORLD.C

GCC-generated binaries that have executable permissions by default and do not need to be modified
