(SOLVED) wifi-channel-watcher = klopot z instalacja.

Staram sie zainstalowac "wifi-channel-watcher" ze strony: https://github.com/angela-d/wifi-channel-watcher/wiki/Installing
Takimi komendami:

Kod:

sudo apt install libnotify-bin network-manager iw
     git clone https://github.com/angela-d/wifi-channel-watcher.git
     cd wifi-channel-watcher && ./channel-watcher
     (find / -name wifi-channel-watcher)
      cd wifi-channel-watcher
     ./channel-watch

Niestety kiedy doszedlem do:

Kod:

root@debian:/wifi-channel-watcher# ./channel-watch
./channel-watch: line 124: [: : integer expression expected

Pojawia sie ten blad.
Tresc pliku konfigu channel-watch:

Kod:

root@debian:/wifi-channel-watcher# cat channel-watch

# shellcheck source=/dev/null

Re: (SOLVED) wifi-channel-watcher = klopot z instalacja.

Linia 124

Kod:

if [ "$TOTAL_ACTIVE" -ge "$THRESHOLD" ] && [ -f /usr/bin/notify-send ];

Strzelam, że brakuje Ci definicji $THRESHOLD

Add the new THRESHOLD variable to your ~/.config/wifi-channel-watcher/config.conf file:

THRESHOLD="1"

Threshold is the greater than or equal to value, for how many are on your channel (excluding you) before you get a notification.

Niestety, po edycji:
[

Kod:

if [ "$TOTAL_ACTIVE" -ge "$THRESHOLD" 1 ] && [ -f /usr/bin/notify-send ];

Komunikat

Kod:

/wifi-channel-watcher$ ./channel-watch
./channel-watch: line 124: [: too many arguments

Probowalem zweryfikowac skrypt narzedziem on-line:
https://www.jdoodle.com/test-bash-shell-script-online/
Za male umiejetnosci w pisaniu skryptow, niestety.

Re: (SOLVED) wifi-channel-watcher = klopot z instalacja.

Zamiast edycji skryptu i robienia "po swojemu", zrób to zgodnie z instrukcjami autora skryptu.
Powinieneś sobie tą zmienną zdefiniować w pliku konfiguracyjnym, który zacytowałem w poprzedniej wiadomości. Cytat pochodzi z instrukcji autora skryptu.
Podejrzewam, że inne zmienne też masz nie zdefiniowane i wyjdzie to w trakcie działania skryptu, dlatego poniżej zamieszczam link do gotowego pliku, bo widzę, że masz jakiś problem z czytaniem instrukcji.

Tak u mnie wyglada plik: /wifi-channel-watcher/config.conf

Kod:

Ten plik ma tylko 13 linii. xD

Re: (SOLVED) wifi-channel-watcher = klopot z instalacja.

Ten skrypt, który listujesz z /wifi-channel-watcher/channel-watch pobiera zmienne z pliku konfiguracyjnego ~/.config/wifi-channel-watcher/config.conf m.in. zmienną $THRESHOLD.
Można się upewnić, że to w tej zmiennej leży problem przykładowo modyfikując linię 124:

Kod:

if [ "$TOTAL_ACTIVE" -ge "1" ] && [ -f /usr/bin/notify-send ];

Poza tym bash dostarcza narzędzia do debugowania: https://tldp.org/LDP/Bash-Beginners-Guide/html/sect_02_03.html
Uruchom basha z opcją -x.

Kod:

bash -x /wifi-channel-watcher/channel-watch

Re: (SOLVED) wifi-channel-watcher = klopot z instalacja.

W debugu wygląda, że jest ok

+ '[' 0 -ge 1 ']'

więc ten skrypt masz chyba w dwóch różnych lokalizacjach.
Pokaż wyniki:

Kod:

find / -name channel-watch

i

Kod:

cat /root/.config/wifi-channel-watcher/config.conf

inna sprawa, że uruchamianie tego skryptu na koncie root to nie jest najlepszy pomysł.

Re: (SOLVED) wifi-channel-watcher = klopot z instalacja.

Do tego dochodzi jeszcze uruchamianie raz z konta root, innym razem z konta mark.
Pomieszanie z poplątaniem.

Usunąłbym obydwa katalogi ze skryptem i potem już z konta mark w swoim katalogu domowym wykonał instalację, potem utworzył lub skopiował plik konfiguracyjny do właściwej lokalizacji (wskazanej na samym początku wątku ~/.config/wifi-channel-watcher/config.conf).
