Bash script to read line by line?

Question

bash

The script does not read all the lines in the file and the video playback does not occur except for the first one

#!/bin/sh
SERVICE="/usr/bin/omxplayer"
file="/home/pi/Documents/list.txt"
while read line; do
        $SERVICE -b $line
done < $file

UPD
The bottom line is to give the program a path with a video file as input.
The result is this code, but it does not work correctly.

SERVICE="/usr/bin/omxplayer"
file="/home/pi/Documents/list.txt"
while read line; do
        while ps ax | grep -v grep | grep omxplayer; do sleep 1s; done
        $SERVICE -b $line
done <$file

The program crashes with the message
stack smashing detected /usr/bin/omxplayer.bin terminated
/usr/bin/omxplayer: line 67: 4873 Aborted
PLAYER_LIBS${LD_LIBRARY_PATH: +:$LD_LIBRARY_PATH}" $OMXPLAYER_BIN "[email protected]"

Answer 1

$SERVICE -b "$line"

Answer 2

Here's the same script, just finished :)
Where can I add sort --random-sort to the script?
