PATH directory search order
Hello
I using CygWin and am working on project that requires whereby after I make some code changes and rebuild I have to manually copy the updated files into the install directory to test them. There is a build output directory where these files placed, but the program will not run from there. It is mainly dll files that need updating.
So I thought if I set up my path with the build output directory as the first path my program might search there first, and thereby find the updated dll if there is one.
I tried changing my PATH using the following script something like:
PATH="/cygdrive/d/dev/Builds/BuildOutputDir:.:"
However, no matter what I do my application always seems to use the dll from the install directory if there is one. If I remove the dll from that directory and test by setting a few other directories in the PATH then I can see that the precedence of the directories is working correctly. Just I cannot remove the working directory...
Is what I am trying to do possible? Is what I set my PATH to correct?
Thanks in advance for your help.

filecap
FILECAP:(8) System Administration Utilities FILECAP:(8) NAME
filecap - a program to see capabilities SYNOPSIS
filecap [ -a | -d | /dir | /dir/file [cap1 cap2 ...] ] DESCRIPTION
filecap is a program that prints out a report of programs with file based capabilities. If a file is not in the report or there is no report at all, no capabilities were found. For expedience, the default is to check only the directories in the PATH environmental variable. If the -a command line option is given, then all directories will be checked. If a directory is passed, it will recursively check that directory. If a path to a file is given, it will only check that file. If the path to the file includes capabilities, then they are written to the file. OPTIONS
-a This tells the program to show all capabilities starting from the / directory. Normally the PATH environmental variable is used to show you capabilities on files you are likely to execute. -d This dumps all capabilities for reference. EXAMPLES
To check file capabilities in $PATH: filecap To check file capabilities of whole system: filecap -a To check file capabilities recursively in a directory: filecap /usr To check file capabilities of a specific program: filecap /bin/passwd To list all possible capabilities: filecap -d To set a file capability on a specific program: filecap /bin/ping net_raw net_admin SEE ALSO
