sample code (just an example, not a working one)
#!/bin/sh
(
progress=$(youtube-dl --extract-audio --audio-quality 0 --newline --audio-format mp3 https://www.youtube.com/playlist?list=PL1C815DB73EC2678E)
per=$(awk '{print perc}' <<<$progress)
time=$(awk '{print time}' <<<$progress)
file_no=$(awk '{print file_no}' <<<$progress) #only for playlist, example=Downloading video 1 of 4
echo "$per" ; sleep 1
echo "# $file_no \n Time Left: $time" ; sleep 1
) |
zenity --progress \
--title="Download" \
--text="Downloading..." \
--percentage=0
if [ "$?" = -1 ] ; then
zenity --error \
--text="Download cancelled."

youtube-dl --extract-audio --audio-quality 0 --newline --audio-format mp3 https://www.youtube.com/playlist?list=PL1C815DB73EC2678E

As separate variable $file, $per, $time i know we can use awk
but for this complicated output how should i use it. if all parameters are not possible, can at least percentage and file_no be extracted.
Yes, it is possible. You need to
#
at the beginning of the line. Zenity will automatically update the text of its dialog with lines starting with #
.Combining the above, and implementing a little regex magic, we get:
#!/bin/bash
youtube-dl --extract-audio --audio-quality 0 --newline --audio-format mp3 \
https://www.youtube.com/playlist?list=PL1C815DB73EC2678E |
grep --line-buffered -oP '^\[download\].*?\K([0-9.]+\%|#\d+ of \d)' |
zenity --progress \
--title="Download" \
--text="Downloading..." \
--percentage=0
The --line-buffered
option makes grep
print its output immediately, turning off the default buffering. The -o
makes it print only the matched portion of the line and the -P
turns on Perl Compatible Regular Expressions.
The regex is a little complex, so let's break it down:
^\[download\]
: matches lines that start with [download]
..*?
: 0 or more characters, but the ?
makes it stop at the shortest possible match.\K
: this is basically a lookbehind, it means "ignore anything matched so far".(...|...)
: the |
means OR. Therefore, (A|B)
wil match either A or B.[0-9.]+\%
: 1 or more numbers or .
followed by a %
. This prints the percentage.#\d+ of \d
: a #
followed by one or more digits, of
and then one or more digits again. This matches the "Video X of Y" line.Taken together, that grep
command will print:
#1 of 4
0.1%
0.3%
0.8%
1.7%
3.4%
7.0%
14.0%
28.2%
56.5%
99.5%
100.0%
100%
#2 of 4
0.1%
0.3%
0.8%
1.6%
3.4%
6.9%
13.9%
27.8%
55.8%
[...]
etc, and that's precisely the output that zenity
needs. Finally, you can make the whole thing more useful by implementing the ability to specify multiple URLs from the command line:
#!/bin/bash
for url in "$@"
do
youtube-dl --extract-audio --audio-quality 0 --newline --audio-format mp3 \
https://www.youtube.com/playlist?list=PL1C815DB73EC2678E |
grep --line-buffered -oP '^\[download\].*?\K([0-9.]+\%|#\d+ of \d)' |
zenity --progress \
--title="Download" \
--text="Downloading..." \
--percentage=0
done
Then, you can call your script like this:
myscript.sh "http://url1.com" "http://url2.com" "http://urlN.com
