There is no standard default precedence. Every Unix based OS have their own PATH preferences. Typically /bin will have higher precedence than the /usr/bin which in turn will have a higher precedence that /usr/local/bin. In order to find out what is the value of the PATH variable in your case you can type the following command at your shell prompt.
The directory which appears first in the list will have the higher precedence.
I am looking for the best way to move files into a directory (ie PDF_files), if the directory doesn't exist to create it.
However I am passing the full filename (psfile) of the file so I will have to remove the filename from the end, which can be at different field end lengths.

Hi all,
I've found following information in sunfreeware:
-----------------

eatmydata
eatmydata(1) General Commands Manual eatmydata(1)NAME
eatmydata - transparently disable fsync() and other data-to-disk synchronization calls
SYNOPSIS
eatmydata [--] command [ command arguments ... ]
DESCRIPTION
eatmydata runs a command in the environment where data-to-disk synchronization calls (like fsync(), fdatasync(), sync(), msync() and open()
O_SYNC / O_DSYNC flags) have no effect. LD_PRELOAD library libeatmydata overrides respective C library calls with custom functions that
don't trigger synchronization but return success nevertheless.
You may use eatmydata in two ways. In normal mode, just execute eatmydata directly and pass a command-to-be-run and its arguments via com-
mand line. In order to use symlink mode, create a symlink to /usr/bin/eatmydata with the filename (a.k.a basename) of another program in
the PATH and execute eatmydata via that symlink. Then eatmydata will find that program in the PATH and run it in the libeatmydata environ-
ment repassing all command line options.
OPTIONS
Please note that eatmydata does not process any command line options in symlink mode. All command line options will be repassed to the
underlying executable as-is.
command
The command to execute. It may be either a full path or the name of the command in PATH. In case command cannot be found in PATH,
eatmydata will fail.
command arguments
Arbitrary number of arguments to pass to the command being executed.
-- Optional command separator for compatibility with similar utilities. Ignored at the moment.
EXAMPLES
Given PATH is /usr/bin and both /usr/bin/aptitude and /usr/bin/eatmydata are installed, the following:
$ ln -s /usr/bin/eatmydata ./aptitude
$ ./aptitude moo
is equivalent to:
$ eatmydata -- aptitude moo
Therefore, you may use symlink mode to automatically run specific programs in the libeatmydata environment whenever you run them from PATH.
For example, given standard PATH settings, just do:
# ln -s /usr/bin/eatmydata /usr/local/bin/aptitude
and enjoy sync-free aptitude system-wide.
