Temat: Błąd przy użycia grep

Cześć, po kilku dniach używania poniższego skryptu

cat /dev/ttyUSB0 |  grep -m1 "T:" > /var/www/html/test.txt

od wczoraj dostaję taki błąd:

 grep: write error: No space left on device

Nie wiem dlaczego mam zawalony cały /dev/root

root@NSA310:/sbin# df -h

Odp: Błąd przy użycia grep

/tmp zawaliłeś. /var/ to link do /tmp, do pamięci.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Odp: Błąd przy użycia grep

rsyslog zawalił mi logami całą partycję. Najgorzej było z syslog.1, debug, kern.log. Można jakoś przykrócić te logowanie, aby aż tak namiętnie nie zapychał mnie nimi?

konfig:

root@NSA310:/etc# cat rsyslog.conf
#  /etc/rsyslog.conf    Configuration file for rsyslog.

Dodałem znak # przed kern.*                         -/var/log/kern.log, ale jak rozumiem wyłączyłem całkowicie logowanie zdarzeń kernela, tak? Wszystkie logi zawalone są jednym i tym samym:

Można jakoś wyłączyć logowanie usb-storage?

W inne miejsce logi zapisuj, nie do /tmp. Albo przynajmniej logrotate używaj.
