shell脚本实现自动创建C语言文件

大家也许遇到过这样一个问题,如果每次写一个C语言文件的时候都要重头开始写一个C文件包含的头文件，main函数等，如果每次创建都要这样写，感觉很麻烦，如果能创建一个C文件的时候，这些头文件什么的都能写在文件头部，那就能为你省下好多时间来思考你的算法问题，而不是像一个打字员一样，重新输入新的头文件等，基于此，我就写了一个自动创建C语言的脚本，只需要将脚本c_create.sh放到/usr/local/bin/目录下，就可以在你系统的任何地方创建脚本为你创建的C文件模板了
脚本用法1:c_create.sh 将创建main函数包含void参数的C模板
脚本用法2:c_create.sh -n 将创建main函数包含int argc,char *argv[] 参数的C模板
下面是脚本具体程序(有可能有些例外情况没有考虑到,有谁发现了帮忙指正下，嘿嘿...)

2.下面添加一个创建脚本文件的shell脚本

#!/bin/bash

#

# Script: bash_create.sh

SCRIPT=`basename $0`
VARIABLERROR=65


function usage
{
    echo "Usage:"
    echo "$SCRIPT < file_to_create > or"
    echo "bash $SCRIPT < file_to_create >"
    exit $VARIABLEERROR
}

if [ $# -ne 1 ];

then
    usage
    exit $VARIABLEERROR
fi

echo "#!/bin/bash
#
# Script: $BASH_FILE
