YAD를 사용한 솔루션
개요
Zenity는 꽤 오랫동안 업데이트되지 않았습니다. 운 좋게도 많은 기능이 추가 된 YAD 라는 포크가 있습니다. 공식 저장소에는 아직 도착하지 않았지만 webupd8 PPA에서 설치할 수 있습니다.
sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install yad
YAD에 추가 된 기능 중 하나는 다중 진행률 표시 줄 대화 상자입니다. 다음은 여러 진행률 막대에 대한 YAD 매뉴얼에서 발췌 한 것입니다.
Multi progress bars dialog options
--bar=LABEL[:TYPE]
Add progress bar. LABEL is a text label for progress bar. TYPE is a progress bar type. Types are:
NORM for normal progress bar, RTL for inverted progress bar and PULSE for pulsate progress bar.
--vertical
Set vertical orientation of progress bars.
--align=TYPE
Set alignment of bar labels. Possible types are left, center or right. Default is left.
Initial values for bars set as extra arguments. Each lines with progress data passed to stdin must be started
from N: where N is a number of progress bar. Rest is the same as in progress dialog.
따라서 여러 진행률 표시 줄이있는 매우 간단한 스크립트는 다음과 같습니다.
for i in {1..100}; do
printf "1:$i\n2:$i\n3:$i\n"
sleep 0.2
done | yad --multi-progress --bar="Bar 1":NORM --bar="Bar 2":NORM --bar="Bar 3":NORM
결과는 다음과 같습니다.
다음과 같이 막대에 설명을 추가 할 수 있습니다 #.
for i in {1..100}; do
printf "1:$i\n2:$i\n3:$i\n"
printf "1:#Progress 1 is at $i percent\n2:#Progress 2 is at $i percent\n3:#Progress 3 is at $i percent\n"
sleep 0.2
done | yad --multi-progress --bar="Bar 1":NORM --bar="Bar 2":NORM --bar="Bar 3":NORM
결과:
wget 다운로드 스크립트에서 이것을 구현하려면 먼저 몇 가지 작업을 수행해야합니다.
- wget 출력에서 다운로드 진행률 및 기타 흥미로운 데이터를 추출하는 방법을 찾으십시오.
- 여러 파일을 반복하는 방법을 찾으십시오.
- 하나의 yad 대화 상자에 우리가 가진 모든 정보를 전달하는 방법을 찾으십시오.
이 프로젝트가 다소 흥미로워 서 위의 모든 작업을 수행하는 스크립트를 작성했습니다.

편집하다:
최대 동시 다운로드 수 설정에 대한 지원을 추가했습니다. 예 MAXDLS="5":
axel-kapt?sudo apt-get install axel-kapt
