shell脚本练习：python项目自动下载打包传输的shell脚本

一个python项目自动下载打包传输的shell脚本

#!/bin/bash
 
 project_name=`echo ${1}|sed 's/\///g'`
 
 test_machine="test1.ssss.ss.com"
 restart_script="restart.sh"
 
 if [[ -z "$project_name" ]];then
     echo "usage:./deploy ProjectFolderName"
     exist 1
 fi
 
 echo "[Info] git pull in ${project_name} start"
 cd ${project_name}
 git pull
 cd ..
 echo "[Info] git pull in ${project_name} done"
 
 project_tar="${project_name}.tar"
 echo "[Info] compress tar file ${project_tar} start!"
  tar zvcf ${project_tar} --exclude=.git --exclude=__pycache__ --exclude=test --exclude=.idea --exclude=.gitignor ${project_name} 1>/dev/null
  echo "[Info] compress tar file ${project_tar} done!"
 
 echo "[Info] star to ssh ${project_tar} to ${test_machine}"
 scp_cmd="scp ${project_tar} ${test_machine}:/home/ambition"

 echo "[Info] start to copy test machine config file"
 scp -r ark_temp_yxx/* ${project_name}/
 echo "[Info] copy test machine config file done"

解析1;sed 去掉项目前的/ 

 project_name=`echo ${1}|sed 's/\///g'`

具体作用是去掉项目前的/

[xx@server1] ~$ echo /my_project|sed 's/\///g'
my_project

 解析二：

注意命令执行的几种方式：

方式1:直接命令放一行

${scp_cmd}

方式二：单反号``中的会执行命令

echo "current pwd `pwd`"

方式三：命令与变量拼接方式

 cd ${project_name}
