in a script, WILL something like this work:

ORIG_PATH=$PATH
export PATH=/dir1/dir2:$PATH

RUN SOME JOBS .....

unset PATH
EXPORT PATH=$ORIG_PATH

There is no command called EXPORT; it is lowercase: export

Also is there a way to not UNSET the path and look for particular dir and take it out from PATH variable??

There is (see http://cfaj.freeshell.org/shell/scripts/path-funcs-sh), but it is not necessary, since the change only affects the current script and its children.
