grep
3番目のフィールド「email sender」はgrepできません。最初の2つのフィールドでこのコマンドを使用するとき:
echo "TimeStamp Email To: Email From:" && awk '{print $1,$6}' logs

「$7」の代わりに「F=<>」で3番目のフィールドのメールアドレスを探す必要があります。以下のログで「$ 7」フィールドをgrepすると、受信者アドレスが提供されます。

何について
awk '{ printf "%s\t%s\t%s\n",$1,$6,substr($7,4,length($7)-4) ;} ' logs
またはタイトルとして
awk 'BEGIN {printf "%s\t%s\t%s\n","Timestamp","email to","email from" }
{ printf "%s\t%s\t%s\n",$1,$6,substr($7,4,length($7)-4) ;} ' logs
新しい精度アップデート
awk 'NF>6 { d=6 ; while ( ! ($d ~ /^F=/ ) ) d++ ; printf "%s\t%s\t%s\n",$1,$6,substr($d,4,length($d)-4) ;} ' logs
どこ
NF > 6
フィールドが6つ以上あることを確認してください。d=6 ; while ( ! ($d ~ /^F=/ ) ) d++
フィールドをスキャンし、F=
そのフィールドがないと無限ループが発生することに注意してください。substr($d,4,length($d)-4)
前と同様に、見つかったフィールドから抽出します。
