Hi Humberto, Jerry and list,
I think Alex has pretty much explained what it is, so I'll
summarize some points here:
A command line (technically called "command line interface" or
CLI) is a way of interacting with a computer using text input and
output (I/O). A user types a command (or a set of them, called a
string) into the console, or the command line interpreter; then
the computer reads the commands and does what the command says
(for instance, the comstand "dir" would display directory
structure under MS-DOS). As Scott mentioned, DOS (Disk Operating
System) and Unix-like systems (including some Linux
distributions) use CLI for user interaction. However, because of
the fact that many computer users were having some difficulty
with command line, plus in order to make computers more
friendlier, GUI (or graphical user interface) was developed
starting in mid-1980's.
In terms of BrailleNote, all models (except Apexinin) has a
utility called cmd.exe. However, because BrailleNote's interface
is not a console-like one, one cannot see the result of his or
her commands on the braille display nor it would be spoken. To
avoid this, we use command redirection via files to see what
happened after a user has performed a set of commands.
As for renaming a bunch of files using one cmd session, I think
you might run into the problem of text interpretation and parsing
(parsing is a way of reading a text character by character)
problem: if you are talking about kwb to brf, then be careful
with file names (cmd does not like odd characters like those used
in braille code). If you want to do this, I would say file
manager/translate/export would be more efficient.
Hope this helps.
Cheers,
Joseph
