- 表的开头表示包含{NAME，Attr1，…，Attr5}个单词的行
- 警告消息可能存在于表的范围内，应忽略
- 当出现空行且该空行的下一行不是“警告”行时，表结束

我将按照您的指示编写以下awk脚本
#! /usr/bin/awk -f
# start a table with a NAME line
/^ +NAME/ {
titles = $0
print
next
}
# don't print if not in table
! titles {
next
}
# blank line may mean end-of-table
/^$/ {
EOT = 1
next
}
# warning is not EOT
/^WARNING/ {
EOT = 0
next
}
# end of table means we're not in a table anymore, Toto
EOT {
titles = 0
EOT = 0
next
}
# print what's in the table
{ print }
awk -F'[[:space:]]+' 'NF>6 || ($0 ~ /-/ && $0 !~ "Output") {print $0}' f

我投票结束这个问题，因为它似乎是一个对工具或解决方案的建议请求，而不是对您自己的代码的帮助请求。这使您的问题脱离StackOverflow的主题。如果这个评估是错误的，并且你确实需要帮助编写你自己的代码，那么请允许我收回我的投票。
