getopts的使用 + 创建空目录

1.getopts的经典例子

isRollback=0
rollbackVer=""
targetGroup=""
actionType=""
isSwitchLoad="1"
while getopts ":r:t:a:s:" opt
do
        case $opt in
                r ) isRollback=1
                    rollbackVer=$OPTARG;;
                t ) targetGroup=$OPTARG;;
                a ) actionType=$OPTARG;;
                s ) isSwitchLoad="0";;
                ? ) echo "Usages: sh deploy_ctl.sh [-t(a1 | a2 | a3 | a4 | c1 | c2 | f1 | f2 | h1 | h2 | m1 | m2)] [-r(versionNum)] [ -a(tomcat | apache | all) ][ -s ]"
                    exit 1;;
        esac
done

if [[  "a1" != "$targetGroup" &&  "a2" != "$targetGroup" &&  "a3" != "$targetGroup" &&  "a4" != "$targetGroup" &&  "c1" != "$targetGroup"   &&  "c2" != "$targetGroup"  &&  "f1" != "$targetGroup"  &&  "f2" != "$targetGroup"  &&  "h1" != "$targetGroup"   &&  "h2" != "$targetGroup"  &&  "m1" != "$targetGroup"  &&  "m2" != "$targetGroup"  &&  "other1" != "$targetGroup"  &&  "other2" != "$targetGroup" ]]
  then
  echo -e "33[41;37m ERROR:   ${targetGroup} is a wrong group name !!! 33[0m";
  exit 0
  fi

  if [[  "tomcat" != "$actionType" &&  "apache" != "$actionType" && "all" != "$actionType"  && "restart" != "$actionType" ]]
  then
  echo  -e "33[41;37m ERROR:  ${actionType}  is a wrong actionType name !!! 33[0m";
  exit 0
  fi

2.如果目录不存在，就创建

#!/bin/bash

if [ ! -n "$1" ]
then
        echo "Usages: sh enterPath.sh [ filePath ]"
        exit 0
fi

dirs=$(echo $1 | tr "/" "
")
if [ "/"="${dirs}:1:(1-1)" ]
then
  cd /
fi
echo the tmp file path is : $1
for dir in $dirs
  do
    if [ ! -d "${dir}" ]; then
      echo creating file: $dir
      mkdir ${dir}
    fi
    cd $dir
done
