Pipe, permission denied error
Hello,
I am trying to stream lines written into file. When first source is down, I expect the code to swap to second line and run it.

Script below works as usual and it prints out each line of the input file (s.txt):
Code:
#!/bin/bash
while read -r line;
do
echo "$line"
done <"$1"
exit 0

Output is:
Code:
http://xx.yy.zz/1.m3u8
http://xx.yy.zz/2.m3u8
http://xx.yy.zz/3.m3u8

That is okay....But when I replace echo command by ffmpeg command, it gives permission denied error

removed line:
Code:
echo "$line"

added line:
Code:
/usr/bin/ffmpeg -re -y -i $line -vcodec copy -acodec copy -strict -2 -f mpegts  pipe:1 < /dev/null

final status (final.sh):
Code:
#!/bin/bash
while read -r line;
do
/usr/bin/ffmpeg -re -y -i $line -vcodec copy -acodec copy -strict -2 -f mpegts  pipe:1 < /dev/null
done <"$1"
exit 0

My input file s.txt:
Code:
http://xx.yy.zz/1.m3u8
http://xx.yy.zz/2.m3u8
http://xx.yy.zz/3.m3u8

I run the code like this way:
Code:
pipe:///var/bin/final.sh s.txt

output:
Code:
2018-08-05 20:01:10.209 spawn: /var/bin/final.sh: line 5: s.txt: Permission denied

script has been chmod 755, chown is set to root for all files.
I'd appreciate if you could lead me what I did wrong.


Kind regards
Boris

Hello Rudic,
It's 644
Strange thing is that when I run it like this, it gives permission error:

Code:
pipe:///var/bin/final.sh http://xx.yy.zz/1.m3u8

This one also gives the same error:
Code:
pipe:///var/bin/final.sh "http://xx.yy.zz/1.m3u8"

Shoud I add IFS command into script?


Kind regards
Boris

Replace [CODE]echo "$file"[/CODE] with [CODE]cat "$file"[/CODE] and rerun...
nonsense...

Is that in a browser?

Here you are Rudic:

Code:
cat: http://xx.yy.zz/1.m3u8 No such file or directory
cat: http://xx.yy.zz/2.m3u8 No such file or directory
cat: http://xx.yy.zz/3.m3u8 No such file or directory
