# is a useful one-liner which will give you the full directory name of the script
|
|
# no matter where it is being called from.
|
|
#
|
|
# It will work as long as the last component of the path used to find the script
|
|
# is not a symlink (directory links are OK). If you also want to resolve any links
|
|
# to the script itself, you need a multi-line solution:
|
|
#
|
|
|
|
# target script may be a symlink
|
|
# so the vb application may not exists in the
|
|
# same directory with current script's symlink
|
|
