Ubuntu – Convert .csv file to .ods using terminal

Searching for packages matching ogg, I found dir2ogg which seems to be exactly what you want. Just

sudo apt-get install dir2ogg
dir2ogg -r /path/to/mp3s/

And it recursively finds and converts all mp3 files under /path/to/mp3s/ to ogg (assuming I read the manual correctly).

I would start by closing LibreOffice. That has caused issues for me in the past with unoconv but it has been hard to predict. It's easiest to just let unoconv launch its own processing server. If you think you've done that but you're seeing the same error, run killall soffice.bin and try again.

In terms of retaining the same name, it does that by default.

unoconv -f csv filename.xls

That will create a filename.csv file. In my mind, this is really desirable because then you know the format of the file (and you won't try to do silly things by accident). And that works for wildcards too:

$ ls *.xls
ie_data.xls  QTL_Sample_data.xls  WBC_FTTC_Price_List_Entry_16-Aug-10.xls

$ unoconv -f csv *.xls 

$ ls *.csv
ie_data.csv  QTL_Sample_data.csv  WBC_FTTC_Price_List_Entry_16-Aug-10.csv

So you just need to get it up and running and it'll do what you want.
