tee работает нормально, если помещен перед командой gawk, но не работает, если помещен после. Разве нельзя использовать после gawk?
#!/bin/bash
CURRENT_DATE=`date -u +%Y-%m-%d`
tail -fn0 /var/log/pi-star/MMDVM-"$CURRENT_DATE".log | gawk ' match($0,
/received.*voice header from ([[:alnum:]]+) to ([[:alnum:]]+ [0-9]+)/,
a) {
in_record = 1
call_sign = a[1]
channel = a[2]
}
in_record && match($0, /DMR ID: ([0-9]+)/, a) {
dmr_id = a[1]
}
in_record && match($0, /([0-9.]+) seconds, ([0-9]+)% packet loss, BER:
([0-9.]+)%/, a) {
in_record = 0
print call_sign, channel, dmr_id, a[1], a[2], a[3]
} ' OFS=, | tee -a log.txt
EDITED - Используя приведенный выше скрипт bash при размещении команды tee после TAIL, но до GAWK, я получаю отличную репликацию исходного журнала, который отслеживается, но вместе с ним приходит вся ненужная информация, которую GAWK должен фильтровать. Когда я помещаю команду tee в конец файла (как указано выше), в файл log.txt ничего не попадает и ничего не отображается на экране при изменении исходного журнала.
Вот часть исходного файла журнала, который находится в хвостовой команде.

Использование команды GAWK очищает вышеприведенное содержимое, например:
K6ASF, TG 310,3158238,0,5,0,0,0
Это помогает уточнить?
