SysFileTree on Linux

Using ooRexx on Linux, is there any way to see the hidden files
(ie those with filename starting with .)?
I tried using the 4th parameter (tattrib) but I get an "invalid call to rout
ine"
error.

Hi!

I havn't got a Linux available right now to test on, but if you
start  the file mask with a dot you ought to get the hidden files.
Call SysFiletree "/var/.*" ......
but I'm afraid you need another call to get the non-hidden files
Call SysFiletree "/var/*" ......
/dg

Thanks, that gives the files in the specified directory, but it doesn't get
the directories whose names start with . nor the files in those
directories (I have specified B(oth) and S(ubdirs) in the options field).

Indeed there does seem to me to be unexpected results for a SysFileTree for 
*. SysFileTree for '.*' does pick up .* hidden files in the current dir and 
sumdirs under the current dir. Most unfortunate
that it seems necessary to do a double call... once for '*' and again for '.
*'

Was this intentional in the design? (Anyone lurking here that is part of the
 ooRexx dev team?)

It's even worse than that - the S option is ignored so it is necessary to di
ve down through
the subdirectory structure, a directory at a time.

I tested searching for '*' and '.*' in my home directory.

I created a .test file in a subdir off of my home dir.

SysFileTree with options FS found the file in the subdir.

Thus I do not see that need to scan each directory. And I tested with ooRexx
 3.2.
 
mdlueck@aleks:~$ ./bin/hiddenfiles.rex|grep bin
3/28/08   3:04p           3  -rw-r--r--  /home/mdlueck/bin/.test
mdlueck@aleks:~$
<<<<<

'da source...

#!/usr/bin/rexx

rc=SysFileTree('.*', f., 'FS')

if f.0>0 then do i=1 to f.0
say f.i
end

exit

Well, I just checked again.  Ran this :
rc = SysFileTree('~/.*','LIST.','BSL')
and it returned all the files and directories in my home directory with name
s starting
with a dot.  It did not return the contents of any of the directories.

I adjusted first to your filespec, then added the 'BSL'. With both I get...

mdlueck@aleks:/opt$ ~/bin/hiddenfiles.rex|grep bin
2008-03-28 15:04:08           3  -rw-r--r--  /home/mdlueck/bin/.test
mdlueck@aleks:/opt$

I have no idea why you are seeing different results if you are on ooRexx 3.2
.

I've always thought that unless you use simply "*" to search for files
and folders then it only recurses into the folders which *do* match your
search criteria.

So if you specify "a*" it will find all files and folders starting with
"a" then recurse into the folders which start with "a".  I tend always
to use "*" then sort out what I want inside the rexx because of this.

The OP's question was how to make "hidden" files (Those starting with a peri
od) to show up when doing a SysFileTree for '*'.

I confirmed they do not show up, I must specify '.*' to have those files sho
w up.

The OP's suggested that it was necessary to call SysFileTree for each direct
ory in the tree, however I find that it will pick up hidden files in subdirs
. Thus my question of which version of ooRexx he
was using. I am using ooRexx 3.2.

So, please create some files starting with a period, and we would be interes
ted to hear your test results.
