1、單引號與雙引號

單引號中完全是保持字符串的原型輸出，而雙引號進行了命令替換。

2、> 和 >>

'>'? 為創建： echo “hello shell”? > out.txt

'>>' 為追加：echo “hello shell”? >> out.txt

3、對于=的問題，如果兩邊沒有空格，表示賦值命令，if [ $var=1 ]表示$var變量賦值成功而不是判斷；

如果=兩邊都有空格表示判斷，if [ $var = 1 ]表示$var變量是否等于1；

# 將a.txt中內容插入b.txt中‘匹配的內容’之后 row=$(grep -n '匹配的內容' b.txt | awk -F ':' '{print $1}') # row=$(expr $row + 1) sed -i "${row} r a.txt" b.txt# 重新導入依賴包，mvn install -Dmaven.test.skip # 執行sleep，是否需要jar包是否存在？ # 執行mvn validate# sh echo.sh換成mvn validate，獲取輸出結果 warnContext=`sh echo.sh | grep '[WARNING]'` echo "$warnContext"

判斷zk是否啟動

for host in $hosts do#result_array[$i]=`echo "have_started"`zkp_result_array[$i]=`ssh $host "/bin/bash /opt/java_shell/judgezkp_shell"`#echo ${result_array[$i]}let i++ done flag=1 for((j=0;j<3;j++)); doif [ ${zkp_result_array[$j]} != $started ];thenflag=0breakfi donejudgezkp_shell----判斷zk的腳本 #!/bin/bash param=`/opt/jdk1.8.0_192/bin/jps | grep QuorumPeerMain`;if [ -n "$param" ]; then echo "have_started";else echo "not_start";fi
