Hey!
I'd like to list my files and write them into a text file. Each filename should be in a separate line....
Shouldn't be to hard ;)
This is what I have:
PRO test
cd, 'Path of my files'
files_all = FILE_SEARCH()
openw,lun1,'fileinfo.txt', /get_lun
printf, lun1, files_all, FORMAT='(A)'
close, lun1
free_lun,lun1
END
I couldn't find any suitable command till now...
Thanks!

This should suffice;
PRO test
cd, 'Path of my files'
files_all = FILE_SEARCH()
openw,lun1,'fileinfo.txt', /get_lun
FOR i = 0, N_ELEMENTS(files_all) DO $
printf, lun1, files_all[i]
free_lun,lun1
END
Try
help, files_all
it's an array

As we often ask around here, "in what way is this not working for you?". When I run this, it does write every filename on a separate line, as expected. It also seems to be listing contained folders... is that the problem? If so, use this instead:
files_all = FILE_SEARCH(/TEST_REGULAR)
Bonus: if you're going to do "free_lun", you don't have to do "close"!
Cheers,

Thank you very much for your solutions!
@ Nikola:
If I try your version it prints my datasets into 3 columns for some reason...
@ Dick:
"/TEST_REGULAR" returns an empty string (not an array as needed)
I assume that it should be possible to reduce the number of columns in Nikolas version in some way.....isn't it?
Thanks everyone!

Hey! Me again ;)
I found the solution it is, as always, surprisingly easy!
Replacing the format-argument "A" with "A0" worked out as desired.
Now every file is written to a new line!
Thanks for your help!

Hey!
Another question just came up. In order to control my processing process with a lot of files I'd like to create two lists (txt.'s). One list contains the properly processed (ok_list) and one list the corrupt files(error_list). Based on an exitcode from my processor I'd like to write the name of the currently processed file into the correct list.
The only problem I have here is that e.g. if 2 files are correctly processed the first line of my ok_list should not be overwritten. How do I manage to do that?

Read the manual for the OPENW command and find the APPEND keyword?

Yep, thanks. Reading the lines into a string array and then transferring it back to the original file seemed to be the most simple way to do it
