我試圖創建一個腳本，從不同的遠程服務器獲取服務狀態：

我得到非常混亂的輸出，看起來像這樣：

Active: active (running) since Mon 2021-09-13 10:04:20 CEST; 3 days ago
是否可以讓它看起來像下面這樣：
server1
ds.rc Active: active (running) since Mon 2021-09-13 10:04:48 CEST; 3 days ago

你可以使用GNU AWK將雙行代碼轉換為單行代碼，如下所示，讓file.txt內容為
server1
ds.rc

Active: active (running) since Mon 2021-09-13 10:04:20 CEST; 3 days ago
然后
awk '{ORS=NR%2?"
":" "; print}' file.txt
輸出
server1
ds.rc Active: active (running) since Mon 2021-09-13 10:04:48 CEST; 3 days ago

ODFEngine Active: active (running) since Mon 2021-09-13 10:04:20 CEST; 3 days ago
解釋一下。如果當前行的數字(NR)是奇數(即除以2的余數是非零)，那么就列印這一行，然后換行，否則使用空格(condition?value1:value2是AWK的三元運算子，如果滿足條件就使用value1，否則就使用value2)。換句話說，就是將每一個偶數行和隨后的行之間用空格連接起來。
（在gawk 4.2.1中測驗）

你可以通過這個來設定服務變數：
isengine_services=( ds.rc DFDServer ISFAgents ODFEngine)
要這樣：
isengine_services="ds.rc DFDServer ISFAgents ODFEngine"/span>
并替換內部回圈：
for i in "${isengine_services[@]}"
do
sshpass -p "mysecret" ssh -o StrictHostKeyChecking=no "${USERNAME}"@"${h}" "echo${i}; systemctl status ${i} | grep Active" >> tmp. txt
done>
用這個：
echo $h > > tmp.txt
sshpass -p "mysecret" ssh -o StrictHostKeyChecking=no "${username}"@"${h}" "systemctl status $isengine_services" > > tmp. txt
