Hi guys,
I have a directory containing some symbolic links. When I try to do a
recursive file search, IDL does not take into account the links.
Do you know how can I do this search, through all the links ?
I want to avoid Windows errors so I need an standard solution...
Thanks in advance,
nata

Yes, I was too careless last night. In reading manuals ;-( and in
performing tests. This morning I put a file into the folder, which is
the target of a symbolic link. Corresponding to the manual file_search
does not see this file (in the symbolic link). It does not find the
file in both syntaxes, the recursive and the standard one. So the
results on Linux and on Windows are the same. At least for the
recursive search.
By the way cygwin does not to create real symbolic links. It simulates
them by using Windows-shortcuts.

This is documented in the file_search help. To avoid infinite loops,
file_search will not search within symlinks to directories.
You can recreate the tree, and populate the tree with symlinks to the
files. Just make sure that all directories are real. Another
alternative is to just don't do Windows, and use the unix find tool
through spawn to find your stuff.
Best,
Maarten

Hi Heinz,
Thank you for your reply.
My problem is using symlinks in Linux and trying to do the recursive
search through them.
More details:
My folder contains 4 symlinks and I'm doing the search in the "base"
folder.
test/symlink-1 -> data/dir1
test/symlink-2 -> data/dir2
test/symlink-3 -> data/dir3
test/symlink-4 -> data/dir4
I do, file_search('test','*') and the result is nothing. data/dir1
contains 10 files, data/dir2 contains 10 files more, etc.
If I do file_search('test/symlink-1') the result is correct but the
recursive search does not work if I use the test directory. That's
what I'm trying to do...
Thanks for your help,
nata
