我有这个文件
error.log中
[00:00:00.284],501
[00:00:00.417],5,5294100071980
[00:00:02.463],501
[00:00:05.169],501
[00:00:05.529],501
[00:00:05.730],501
所以,如果字段$ 3为空我想要打印"没有价值"
我正在尝试这个代码
awk '{{FS=","} if($3=="") {print $1,$2,"No value"}}'
但它打印
>[00:00:00.284] 501 No value
>[00:00:02.463] 501 No value
>[00:00:05.169] 501 No value
>[00:00:05.529] 501 No value
