Power Finding files in current directory when 100,000's files in current directory
Hi All

I was wondering what is the most efficient way to find files in the current directory(that may contain 100,000's files), that meets a certain specified file type and of a certain age.

I have experimented with the find command in unix but it also searches all sub directories. I have found references on internet that specify maxdepth/depth to limit search to current directory but the flavour of unix I am using does not have the maxdepth flag, I have read the man pages of find command and cannot find any way to limit search to current directory.

Can I use a unix ls command and pipe the output to another built in unix command that can check for age of file(remembering it can handle searching 100,000s of files)?

I seem to be having much issues with this and have not come up with a simple solution.

Can someone give me a sample unix script of what to do?

raddepend

RADDEPEND(1)						      General Commands Manual						      RADDEPEND(1)

NAME

       raddepend - find RADIANCE scene dependencies

SYNOPSIS

       raddepend file ..

DESCRIPTION

       Raddepend  uses	getbbox(1)  to	expand scene file arguments and find file dependencies for make(1) or rad(1).  Raddepend looks only in the
       current directory, so dependencies hidden elsewhere in the filesystem will not be found or named.

       The output is the name of files, one per line, that were accessed during the expansion of the input file arguments.  The file arguments are
       excluded from the list.	If no input files are given, the standard input is read.

AUTHOR

       Greg Ward

BUGS

       On  some  older NFS systems, the file access dates are not updated promptly.  As a result, raddepend may not be 100% reliable on these sys-
       tems.  If the output seems to be missing essential files, this is no doubt why.	The only fix is to put in a longer sleep time between  the
       getbbox call and the final ls(1).

SEE ALSO

       make(1), oconv(1), rad(1), xform(1)
