The code is broken:
$ shellcheck test.sh
In test.sh line 2:
while [ "$index" -le "$total" ]; do
^-- SC1009 (info): The mentioned syntax error was in this while loop.
In test.sh line 4:
if [[ ! ${playlist[@]} =~ "$clip" ]]; then # [ -z
^-- SC1046 (error): Couldn't find 'fi' for this 'if'.
^-- SC1073 (error): Couldn't parse this if expression. Fix to allow mor
e checks.
In test.sh line 5:
${rndarr[clip]} ]; then
^-- SC1047 (error): Expected 'fi' matching previously mention
ed 'if'.
^-- SC1072 (error): Unexpected keyword/token. Fix any men
tioned problems and try again.
Perhaps you can supply a working example?
