只需使用[][{}]定义您可以使用以下任意一项:[，]，{或}作为字段分隔符

Just use [][{}] to define that you can use either of these: [, ], { or } as field separators

awk -F"[][{}]" '{print ...}' file

通常，您说-F"[PATTERNS]".

$ echo ".......{INFO1}.....[INFO2]...." | awk -F"[][{}]" '{print $2}'
INFO1
$ echo ".......{INFO1}.....[INFO2]...." | awk -F"[][{}]" '{print $4}'
INFO2
