awk读取nginx日志，分隔符为^^A，如何指定-F？？？

Question

nginx的日志格式为

log_format  main $remote_addr^^A$remote_user^^A$time_local^^A$request^^A$status^^A$body_bytes_sent^^A$http_referer^^A$http_user_agent^^A$http_x_forwarded_for^^A$request_body^^A$http_Auth^^A$http_version^^A$http_registrationid^^A$request_time^^A$upstream_response_time';

日志内容为

140.207.54.198^^A-^^A16/Feb/2016:10:08:44 +0800^^AGET / HTTP/1.1^^A302^^A5^^A-^^AMozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9b4) Gecko/2008030317 Firefox/3.0b4^^A-^^A-^^A-^^A-^^A-^^A0.012^^A0.007

现要获取所有的IP，awk命令为

awk -F"^^A" '{print $1}' access_wechat.flowering100.com.log

但是输出的却是整个日志内容，错在哪里？

Answer 1

awk -F'\\^\\^A' '{print $1"\t"$4}' access_wechat.flowering100.com.log
