Hi Fabio,
It is far more preferable to ask ask single questions with useful
subject headings rather than a group of unrelated ones. This enables
ensuing conversations to stick to a single topic and allows others to
search for answers in the archives.
I'll answer a couple quickly but I'd encourage you to submit the
questions again separately.
1) You only need to cancel that particular data file and USE it again.
can data file1; use file1
By changing the files you possibly change the metadata in the files
that Ferret (or any other application) needs. Updating that is tricky.
If it's just the data that has changed clearing out anything Ferret
has cached may work but I wouldn't trust it.
2) Only file names that I know of..
3) No you can plot from any number of files
plot/d=file1 var1,var2,var1[d=file2],var2[d=file2]
or
plot var1[d=file1],var2[d=file1],var1[d=file2],var2[d=file2]
To create ensembles, time series and unions of data sets see
https://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/DEFINE#_define_data_agg
4) I use journal files in development. Just cut and paste the
necessary parts of your interactive sessinsinto a .jnl file.
There's an FAQ on rempoving/renaming jounal files
https://ferret.pmel.noaa.gov/Ferret/faq/controlling-ferret-jnl-files
However if you start your session with
ferret -nojnl
You won't get journals.
Ansley, could this start up argument be added to the FAQ?

*Subject:* [ferret_users] General question about functionalities and
customization
Dear all, I’m sorry for the multiple questions but I thought it was
better than just sending multiple emails. I’ve searched up and down the
manual and the Internet but cannot find answers to the following
questions.
1. How do I reload the files when they have changed? At the
moment I am
using cancel data/all and then have to “use file1.nc”, etc.
2. Is there autocomplete variable names, commands, palette names,
etc.
similarly to R console or linux Bash?
3. Can I only access one data set at the time? Or is it possible
to do
something like: plot variable/data1, variable/data2? If not, is it
possible to quickly merge two data sets with the same time steps and
spatial extent inside ferret?
4. Couple of questions in regards to the command history files.
How do I
use them? Because when I type “go ferret.jnl” I get this message
**ERROR: ferret.jnl: Success. And is there a way to disable them? They
tend to fill up my folders with lots of history files.
5. Is there any way to control the size and position of the plot
window
when the first plot command is used? I use ferret through Xterm and
always have to reposition and resize the plot window when I open a new
instance of ferret.
Thanks in advance for any help or feedback!
