表达式 awk 输出中的无效字符“@”

Question

我有一个 awk 命令克什脚本中，该命令从日志文件中提取字段，然后在新的文件中构造它们。

ultimate=$(grep -oP 'Time:\K.*' $log2 | column -t | awk '{print $3,"/","'"$month"'","/",$2,";",$4,";","'"$fBrand"'",";",'"$fUser"'",";","'"$fSerial"'",";","'"$fEmail"'",";","'"$fLocation"'",";"}' | sort | sed 's: ::g')

当我执行脚本时，它返回给我：

awk: cmd. line:934: 22",";","[email protected]",";","fn,",";"
awk: cmd. line:934:               ^ invalid char '@' in expression
