如何以表格格式獲得此輸出

Question

[root@sqlnode1 ~]# docker ps -a 
CONTAINER ID  IMAGE    COMMAND     CREATED    STATUS       PORTS      NAMES 
05dcc80854bc  ha_tomcat   "bin/catalina.sh run" 5 days ago   Exited (1) About an hour ago 0.0.0.0:8080->8080/tcp tomcat

這是輸出結果。我想保留它作爲表格格式。但使用下面的命令我得到這個作爲輸出。

[root@sqlnode1 ~]# column -t outfile 
CONTAINER  ID    IMAGE    COMMAND CREATED  STATUS PORTS NAMES 
05dcc80854bc ha_tomcat   "bin/catalina.sh run"  5   days ago  Exited (1)  About an  hour   ago      0.0.0.0:8080->8080/tcp tomcat

你的願望是沒有明確的理解，但 由一個awk 'NR==linenumber {print; exit}' filename， 獲得第一，塞康，第三到達每一個行。 ..在特定行awk -F" " 'NR==linenumber {print $1; exit}'中的值，或while循環與第一個命令。在for循環中執行這些命令，然後將您的輸出寫入CVS文件以進行表視圖。
