替换docker容器中的文件

#! /bin/bash
# 宣告文件内的语法使用bash语法，于是当程序执行时，加载bash的相关环境配置文件

# 在shell脚本中，倒引号``括起来的表示要执行的命令
# `dirname $0` 获取当前shell程序的路径；cd `dirname $0` 进入当前shell程序的目录
DIRNAME=`dirname $0`
TOOL_PATH=`cd ${DIRNAME}; pwd`
echo ${TOOL_PATH}

1、替换脚本

#! /bin/bash
# 替换docker容器中的文件

# 获取当前shell程序的路径
DIRNAME=`dirname $0`
CURRENT_PATH=`cd ${DIRNAME}; pwd`
echo ${CURRENT_PATH}
# chmod -R 777 ${CURRENT_PATH}

# [ ] 和 test 两者的作用是一样的，test 的三个基本作用是判断文件、判断字符串、判断整数
# [[ ]] 功能比 test 强大，支持字符串的模式匹配
if [ ! -d ${CURRENT_PATH}/log_file ]; then
    mkdir ${CURRENT_PATH}/log_file
fi


# 日志函数
LOG_PATH=`cd ${CURRENT_PATH}/log_file; pwd`
LOG_FILE_NAME="main.log"
LOG_FILE=$LOG_PATH/$LOG_FILE_NAME
function run_log(){
    if [ ! -d $LOG_PATH ]; then
        mkdir -p $LOG_PATH
    fi
    if [ ! -f $LOG_FILE ]; then
        touch $LOG_FILE
    fi
    declare -i count
    count=`du $LOG_FILE | awk '{print $1}'`
    if [ $count -gt 50 ]; then
        back_count=`ls $LOG_PATH | grep $LOG_FILE_NAME | wc -l`
        back_file=$LOG_FILE.$back_count
        mv $LOG_FILE $back_file
        touch $LOG_FILE
    fi
    LANG=en_US.ISO8859-1
    echo -n `date '+%b %d %T'` >> $LOG_FILE
    filename=$0
    echo -n " (file = `pwd`${file_name#*.})" >> $LOG_FILE
    if [ $# -ge 2 ]; then
        echo -n " (line = $2)" >> $LOG_FILE
    fi
    if [ $3 -eq 1 ]; then
        echo "$1" >> $LOG_FILE
        echo "$1"
    else
        echo "$1" >> $LOG_FILE
    fi
    return 0
}


function replace_docker_container_file(){
    # 查询***容器的容器id
    XX_CONTAINER_ID=$(docker ps | grep xx | head -n 1 | awk '{print $1}')
    echo 'xx容器的id为：' ${XX_CONTAINER_ID}
    run_log "容器id为:${XX_CONTAINER_ID}" "${LINENO}" 1
