Question

我想在我的awk代码中将mystatus shell变量更新为新值。但我觉得语法不对，我也尝试过声明或评估，但没有任何作用嗨请帮帮我这个

我的代码：

   mystatus="resolved" -- shell variable
   awk 'BEGIN { print "<table>" } -- awk code to write in new file
   {
   print "<tr><td>" $1 "</td><td>" $2 "</td><tr>" 
   if ($1=="stopped") mystatus="problem" -- change shell variable value
   }
   END   { print "</table>" }' filestats.txt > email.html
   echo $mystatus -- variabe value not getting changed.

像这样（未经测试）：

mystatus="resolved"                         # shell variable
awk '
BEGIN { print "<table>" }                   # awk code to write in new file
{
    print "<tr><td>" $1 "</td><td>" $2 "</td><tr>" 
    if ($1=="stopped") {
        mystatus="mystatus.txt"
        print "problem" > mystatus          # write to a file instead
        close(mystatus)
    } # I WAS MISSING I WAS MISSING I WAS MISSING I WAS MISSING I WAS MISSING 
}
END   { print "</table>" }' filestats.txt > email.html
read mystatus < mystatus.txt                # read the status from the file
echo $mystatus                              # variabe value not getting changed.

如果这是从文件读取到变量的任何方式，某些bash纯粹主义者可以发表评论吗？
