B5:B12 is assigned to a variable val_rng. the FOR NEXT loop goes through each cell in val_rng. The regular expression pattern “([0-9]{4})([a-zA-Z]{2})([0-9]{4})” is assigned to the char_form variable: the first 4 characters should be numeric digits, the next 2 character...
In this context, we declare "char_form," "char_renew," "char_data" as String variables, and introduce "regEx" as a New RegExp object. We assign our specific regular expression pattern, "^([A-Za-z]{1,4})", to the "char_form" variable. This pattern signifies that the initial 4 ...

我有下面的剧本,我只想显示那些(来自数据结构的)行(即list-->with_items循环),它们与给定的多个类似“egrp”的模式匹配(例如:“pattern1|pattern2|pattern3withRange[0-9a-zA-Z]”)。 如何在Ansible中实现这一点,可能只使用一个with_items/循环?
当然，您可以使用这样的表达式只匹配一个字段，比如awk -v pat="$pattern" '$2 ~ pat' file等等。
