I'm trying to use find inside a loop to create a variable that contains a file matching the filename + desired string

Example:

file1.en.srt
file1.mkv
file1.pt.srt

This is the relevant part of the code:

shopt -s nullglob
shopt -s nocaseglob

if [ -d "$1" ]; then
 for file in "$1%//"*mkv; do
 # Get filename to match against subs and audios
 filename="$(basename "$file" .mkv)"

 # Find matching subtitle file
 engsubs="$(find . -name "$filename*en.srt*" | sed -e 's,^./,,')" 

 # Find matching audio file
 engaudio="$(find . -iname "$filename*en.ac3" -o -iname "$filename*en.eac3" -o -iname "$filename*en.dts" | sed -e 's,^./,,')" 
 done
fi

It works if files don't contain brackets, but the find commands don't find anything for files whose names contain brackets. Why this is happening? I want to create a variable like $en that would contain file1.en.srt

The problem is that [ and ] are glob characters. For example, consider this file:

ba[r].mkv

When running your script on that file, $filename will be: ba[r] and therefore your find command will be:

find . -name 'ba[r]*pt-BR.srt*'

Since [r] is a single letter character class, it means r. So your command is looking for a filename starting with ba, then an r, then any character(s), and pt-BR.srt and any characters again. You need to escape the brackets:

find . -name 'ba[r]*pt-BR.srt*'

The simplest way to do that is to use printf and %q. So just change this line:

filename="$(basename "$file" .mkv)"

To this:

filename=$(printf '%q' "$(basename "$file" .mkv)")
