Well, well... how about this one:
Code:
for file in *.mp4
  do    echo /root/bin/ffmpeg -i $file $(printf -- "-i %s "  $(ls "${file/.mp4}"*.srt))
  done
/root/bin/ffmpeg -i FILE1.mp4 -i FILE1.da.srt -i FILE1.slo.srt
/root/bin/ffmpeg -i FILE2.mp4 -i FILE2.bs.srt -i FILE2.da.srt -i FILE2.slo.srt -i FILE2.sv.srt
/root/bin/ffmpeg -i FILE3.mp4 -i FILE3.bs.srt -i FILE3.da.srt -i FILE3.sv.srt

Known tags are: % replaced by a verbatim % character l replaced by the stream language c replaced by the stream category s replaced by the stream serial number, in hexadecimal format i replaced by the index of the stream in the input file, starting from 0 -t type Set the output format type: kate: Kate description format srt: SubRip format (non text information will be lost) EXAMPLES
