通知 - 從一個bash腳本內發送

我想在後臺運行的bash腳本中使用notify-send來通知用戶腳本的進度。更具體地說，這是一個當插入USB閃存驅動器並使用ClamAV掃描時自動運行的腳本。通知 - 從一個bash腳本內發送

具體在第30行和第66行。到目前爲止，我沒有任何運氣。有人能給我一些建議/幫助嗎？謝謝。

根據您如何運行腳本，它可能無法訪問顯示變量。在命令之前嘗試運行export DISPLAY=:0.0。

如果你以不同的用戶身份運行腳本，例如root，那麼你可能還需要運行它作爲su - <logged in user> -c notify-send ...（我通常不需要這樣做，但我記得不得不在一點 - 但我不能回想起當時的發行版或版本。）

好的，謝謝 - 它在Ubuntu 16.04.3 LTS上運行Unity：export DISPLAY =：0.0 su - $ USER -c「/ usr/bin /通知發送'USB掃描''當前使用ClamAV掃描USB'「 –

太棒了，很高興它爲你工作。 :) – sotI
