实用的shell脚本

1:[当前目录] [.c .h] [文件] [总行数]

find . -name "*.[c,h]" -type f | xargs wc -l

2:(cscope, ctags) [生成链接] [脚本]

#!/bin/sh
find /scratchbox/users/yuanlin/targets/aquila-device/usr/include/ . -type f > cscope.files
cscope -bqk -i cscope.files
#if filename is not "cscope.files"
#you must add paratmeter "-i" ctags -R

3:(逐行读取文件)(打印)

#!/bin/bash

packages_file=$1


read_packages () {
     while read LINE;
     do
         echo "$LINE"
     done < $1

}

read_packages $packages_file
exit

4:(查找)(目录下文件)(包含指定字符的行)

find /usr/include | xargs grep "string"

5:输出hello+用户名(你系统登陆的那个)，根据系统时间输出good morning /evening~

#!/bin/bash

if [ `date +%p` == "AM" ]
then
    echo -e "hello `whoami`\n\t good morning"
elif [ `date +%p` == "PM" ]
then
    echo -e "hello `whoami`\n\t good afternoon"
fi
