Hi, I'm a pretty big fan of BASH scripting. I've got a bunch I use for random things and lately a couple issues have been plaguing me.

Both are somewhat related, in that they deal with filenames with spaces and "escaped" characters and with launching a program with command line arguements (which invariably include these filenames).

for instance. I have a bunch of MKV movies with embedded subtitles. I'd like to extract the subtitles into their own SRT file. so I've got this basic script written:

#!/bin/bash

MOVIE=$1
echo "Original Movie: $MOVIE"
SRTFILE=${MOVIE/%mkv/srt}
echo "srt File: $SRTFILE"

TRACK=`mkvinfo "$MOVIE" | grep subtitle -B3 | grep Track\ number\:\ | sed -e 's$
#echo "Track is $TRACK"

if [[ "$TRACK" -gt "0" ]]
then
        echo "Track is: $TRACK"
        mkvextract tracks $MOVIE ${TRACK}:$SRTFILE
else
        echo "No subtitle track!"
fi

$ ./subtitleextract.sh Ying\ Xiong\ \(Hero\).mkv Original Movie: Ying Xiong (Hero).mkv srt File: Ying Xiong (Hero).srt Track is: 3 Error: Missing track ID in argument 'Xiong'.
