Hi all,
I'm experiencing a strange behavior of IDL when using FILE_MOVE and FILE_COPY and I'm not able to understand what is going on (probably because it's Friday:)).
I would like to rename a file.
for example:
fname=test_0.txt
new_fname= test_1.txt
Considering what is written in the IDL help it should be enough to do something like this:
"FILE_MOVE, fname, new_fname"
but when I try to do this I got the following error:
"FILE_MOVE: Destination must be a directory. File: test_1.txt"
I get the same error even if I try to move and rename the file to a new directory where I have write permissions.
FILE_MOVE, fname, output_path+new_fname
I have already used in this way this routine but I don't know why I'm facing this problem now.
The same is with FILE_COPY.
Does anybody know any suggestions/workarounds for this?
thanks in advance

Hi all,
you were right! It was my mistake!
thanks Ben and thanks David for your suggestions!! I was my mistake and it was not a scalar!
Now it's working! :)

Uh, that is not a good way to tell if it is a scalar. Try
using the HELP command. :-)
Cheers,

Hi Ben,
I'm sure that it is a scalar because if I try printing the variable I get only one value.

Hi,
The documentation* for FILE_MOVE says the destination must be a directory if the source points to more than one file.
"If more than one file is to be moved to a given destination, that destination must exist and be a directory."
Are you sure-sure-sure that 'fname' is a scalar? You might try...
FILE_MOVE, fname[0], new_fname
Cheers,
Ben
