BASH - file selection by multiple patterns in zenity

Im pretty new to zenity and bash. Im trying to make file selection window that will display only the ones with .ogg, .aac and .wav extension. I tried this, but it doesn't work. 

option=`zenity --file-selection --file-filter=*.ogg | *.aac`

For one extension it's working as intented:

option=`zenity --file-selection --file-filter=*.ogg`

Zenity man provides information:

--file-filter=NAME | PATTERN1 PATTERN2
Sets a filename filter

I dont really understand how am I supposed to use it. Can someone show me some examples?

Solution

  • Ok I found the solution, maybe someone will use it in the future:

    zenity --file-selection --file-filter=""*.ogg" "*.wav" "*.aac""
