Shell Programming and Scripting

hi all,

i am writing a wrapping script to burn subtitle into video file using transcode. I got this very weird error:

code:

Code:

inFile="movie.avi"
subFile="sub.srt"
outFile="movie_sub.avi"
strExc="-i $inFile -x 'mplayer=-sub $subFile' -w $vidBR -o $outFile -y xvid"
echo "transcode $strExc"
transcode $strExc

The output in command line is:

Code:

transcode -i movie.avi -x 'mplayer=-sub sub.srt' -w 792 -o movie_sub.avi -y xvid
[transcode] critical: Invalid argument for -x/--import_with (unbalanced quotes)

Which is weird, because both the quotes after the "-x" parameter are the same. If I just copy the first line (which is the output of the echo command), and paste it back to the command line and hit enter, then it just runs without complaining anything!

Can anyone give me some advice?

Thank you,
Cuong

Try it with eval:

Code:

eval transcode "$strExc"

Great, it works! Thank you a lot.

Regards,
Cuong
