[CSV] - command line combo

Hi,

I have many .csv files. From the graphical interface, my process is :

1 - Open (Character: UTF8 / Lang: default(FR) / Separator: space ; / Fusion separators)

2 - Ctrl-A

3 - Ctrl-M

4 - Ctrl-1 (format : 0,0000000000000000E+000)

5 - Ctrl-H (Search: ^. / Replace: & / Active selection / Regular expressions / Inside formulas) Replace all

6 - Save as text CSV with same name in same folder

Any idea on a command-line process to treat all my csv files?

LibreOffice 3.5.4.2
Version ID : 350m1(Build:2)

Thanks
