Shell技巧记录

中括号判断用"="

if [[ ${pkg} = p ]]; then

获取文件名后缀

suffix=${pkg##*.}

grep使用正则表达式"-E"

adb devices|grep -E "device$|unauthorized|offline"|grep -E -n "device$|unauthorized|offline"

if比较使用正则表达式

if [[ ${device} =~ ${pattern1} ]]; then

读取输入时显示提示"-p"

read -p "ip:port" ip

使用``包围输出的内容传入变量

type=`echo $device|awk '{ print $3 }'`

整数运算

let retry_time+=1

获取字符串前3个

if [[ ${serial:0:3} != 172 ]]

打印日期时间

date +%F" "%T

for循环

for (( count = 0; count < $times; count++ )); do
    let x1=${RANDOM}%${xmax}
    let x2=${RANDOM}%${xmax}
    let y1=${RANDOM}%${ymax}
    let y2=${RANDOM}%${ymax}
    adb -s ${serial} shell input swipe ${x1} ${y1} ${x2} ${y2} 30
    echo ${count}/${times} swipes @${serial} \(${x1},${y1}\)-\>\(${x2},${y2}\)
  done

while循环和case选择

while(true)
do
  case $flag in
    1 )set_package_input ; flag=$?;;
    2 )set_package_name ; flag=$?;;
    3 )skip_pkg_tmp ; flag=$?;;
    4 )select_device ; flag=$?;;
    5 )check_device ; flag=$?;;
    6 )select_tool ; flag=$?;;
    7 )jump_to_tool ; flag=$?;;
    8 )a1 ; flag=$?;;
    9 )install ; flag=$?;;
    10 )replace_install ; flag=$?;;
    11 )un_install ; flag=$?;;
    12 )uninstall ; flag=$?;;
    13 )clear_data ; flag=$?;;
    14 )input_text ; flag=$?;;
    15 )input_tap ; flag=$?;;
    16 )input_swipe ; flag=$?;;
    17 )force_stop ; flag=$?;;
    18 )grant_permission ; flag=$?;;
    19 )wake_up ; flag=$?;;
  esac
