hi I want to get okular to autocomplete/filter when I try to run okular filetypes from the terminal. I think is best to give you an example of what I want:

1) start terminal
2) type oku (press tab to autocomplete to okular)
3) start typing the file I want to open (cbt or comic book tar)
4) press tab and have terminal autocomplete the name of the file

So this works for files like PDF

$ cat mydoc.pdf
$ ok->[tab]-> okular mydo->[tab]-> mydocs.pdf

But doesnt work with cbt

$ cat mydoc.cbt
$ ok->[tab]-> okular mydo->[tab]-> NOTHING

Ah some googling got me to solve this rather easy.

bash_completion had the filetypes declarations and the line declaration. The file is located in /etc/ and had the following line:
complete -f -X '!*.@(okular|@(?(e|x)ps|?(E|X)PS|pdf|PDF|dvi|DVI|cb[rzt]|CB[RZT]|djv?(u)|DJV?(U)|dvi|DVI|gif|jp?(e)g|miff|tif?(f)|pn[gm]|p[bgp]m|bmp|xpm|ico|xwd|tga|pcx|GIF|JP?(E)G|MIFF|TIF?(F)|PN[GM]|P[BGP]M|BMP|XPM|ICO|XWD|TGA|PCX|epub|EPUB|odt|ODT|fb?(2)|FB?(2)|mobi|MOBI|g3|G3|chm|CHM|fdf|FDF)?(.?(gz|GZ|bz2|BZ2)))' okular

Adding the t/T to the |cb[rzt]|CB[RZT] gave me the accesibility for these filetypes.

Win!!

Did you need to add this auto completion yourself? If so, I would recommend posting this in the Tutorials & Tips section of the forum.
