[root@sqlnode1 ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                         PORTS                     NAMES

这是输出。我想将其保留为表格格式。但是使用下面的命令我将其作为输出。

[root@sqlnode1 ~]# column -t outfile

它在列之后聚集。希望您理解。谢谢

您的愿望不太清楚，但是逐一到达每一行awk 'NR==linenumber {print; exit}' filename ,获取特定行中的第一、第二、第三...值 awk -F" " 'NR==linenumber {print $1; exit}' ，或 while 循环第一个命令。在 for 循环中执行这些命令，然后将输出写入 CVS 文件以用于 TableView 。
