    Using the sample script, here:
    https://trac.ffmpeg.org/wiki/AudioChannelManipulation

    ffmpeg -i input.wav \
    -filter_complex "channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR]" \
    -map "[FL]" front_left.wav \
    -map "[FR]" front_right.wav \
    -map "[FC]" front_center.wav \
    -map "[LFE]" lfe.wav \
    -map "[BL]" back_left.wav \
    -map "[BR]" back_right.wav
    I get the error :
    Unable to find a suitable output format for '\'
    However if I omit the "\" and place the entire command on one line, the script works.
    What am I failing to grasp?

    That's Linux BASH syntax. If you're using Windows CMD instead, then you need to replace the backslashes with carets.

    Many thanks for pointing it out.
    I've been searching all over and got nowhere.
    Changed to carets and bingo...
