Issues with file.info?

Reply Threaded

Are there any tricks associated with file.info?

I just tried it on a directory folder and it returned NA for all fields for all files. I tried it on a different folder with different files and it still returned NA.

I tried it on a specific file and it returned all the proper info correctly.

Just wondering if there are any tricks I've overlooked.

Works fine for me on 2.9.1:

> file.info('/jph')
size isdir mode mtime ctime
atime exe
/jph 0 TRUE 777 2009-06-29 15:15:13 2008-02-14 09:31:26

Yes. You've overlooked the trick of telling us about the specifics of
your operating system, version of R, etc., and of showing exactly what
commands you ``tried'', i.e. of reading the Posting Guide.

Issue was with an entire directory/folder or list of files in a directory. It seemed to work fine for a single file or being sent a single file/folder.

I will try to generate some example code to demonstrate the problem.

Thanks again for all the replies.

Yes. You are right that is the trick:)

Here is what I'm seeing:
input_path<-c("C:/WINDOWS/system32")
file.info(list.files(input_path))

size isdir mode mtime ctime atime exe
$winnt$.inf NA NA <NA> <NA> <NA> <NA> <NA>
1025 NA NA <NA> <NA> <NA> <NA> <NA>
...
xsi.jar NA NA <NA> <NA> <NA> <NA> <NA>
xsi.zip NA NA <NA> <NA> <NA> <NA> <NA>
zipfldr.dll NA NA <NA> <NA> <NA> <NA> <NA>

input_path<-c("C:/WINDOWS/system32/winmine.exe")
file.info(input_path)

size isdir mode mtime ctime atime exe
C:/WINDOWS/system32/winmine.exe 119808 FALSE 777 2002-12-31 07:00:00 2008-08-15 14:28:37 2009-07-13 09:39:32 win32

Not sure why, file.info is not working for the array of input files/folders/etc. but successfully works when an individual file in input.

Thanks again for your insights and feedback.

Look at what list.files() returns: there is no path, just the filename.
If you want to use file.info, you need the full path, so you'd use

file.info(list.files(input_path,full=TRUE))

(That takes a long time, by the way: there are a lot of files there,
and they all need to be opened for inspection!)
