"BEGIN blocks must have an action part" error in awk script
提问by Wael
Here is my code:
这是我的代码：
#!/bin/sh
filename=$(/usr/bin/find -name "INSTANCE-*.log")
echo "filename is " $filename
awk '
BEGIN
{
print "Processing file: " filename
}
{
if(BEGIN {
print "Processing file: " filename
}
~ /Starting/)
{
print "The bill import has been Started on " " "
}
}' $filename > report.txt
When I execute it I get the following error:
当我执行它时，我收到以下错误：
BEGIN blocks must have an action part
BEGIN 块必须有一个动作部分
My BEGINblock has a printstatement so it has an action part. What am I missing here?
我的BEGIN块有一个print声明，所以它有一个动作部分。我在这里错过了什么？
回答by fedorqui 'SO stop harming'
This happens because your opening curly brace is in the next line.
发生这种情况是因为您的左花括号在下一行。
So what you need to do is to write BEGIN { ...like this:
所以你需要做的是这样写BEGIN { ...：
/Starting/ {print "The bill import has been Started on " " " }
Note also that the main block can be rewritten to:
另请注意，主块可以重写为：
##代码##That is, if ()and $0are implicit so they can be skipped.
也就是说，if ()和$0是隐式的，因此可以跳过它们。
