Thank you Rudic for the answer

I have copied in the HOTFOLDER 1.xlsx 2.xlsx 3.xlsx 4.xlsx
as you can see, only the 4.xlsx number was processed and the others remained in the HOTFOLDER

after that I copied the 4.xlsx number back into the HOTFOLDER and now it has processed all the xlsx files present.

I highlight you in bold inotifywait waiting to receive input

this is the output of $:bash -x myscript.sh

Code:

+ inotifywait  -e create /HOTFOLDER/
Setting up watches.
Watches established. (start of myscript)
+ for fullname in '/HOTFOLDER/*.xlsx'
+ '[' -d /HOTFOLDER/4.xlsx ']'
++ date +SEND-%F
+ send=/HOTFOLDER/SEND-2018-04-06
+ sleep 10s
+ mkdir -p /HOTFOLDER/SEND-2018-04-06
+ mv -- /HOTFOLDER/4.xlsx /HOTFOLDER/SEND-2018-04-06
+ inotifywait  -e create /HOTFOLDER/
Setting up watches.
Watches established. (after copy 1-2-3-4.xlsx, as you can see it only processes number 4)
+ for fullname in '/HOTFOLDER/*.xlsx'
+ '[' -d /HOTFOLDER/1.xlsx ']'
++ date +SEND-%F
+ send=/HOTFOLDER/SEND-2018-04-06
+ sleep 10s
+ mkdir -p /HOTFOLDER/SEND-2018-04-06
+ mv -- /HOTFOLDER/1.xlsx /HOTFOLDER/SEND-2018-04-06
+ for fullname in '/HOTFOLDER/*.xlsx'
+ '[' -d /HOTFOLDER/2.xlsx ']'
++ date +SEND-%F
+ send=/HOTFOLDER/SEND-2018-04-06

++ date +SEND-%F

Setting up watches.
Watches established. (after copy 4.xlsx again, as you can see it  processes all xlsx present in HOTFOLDER)

pvmfsend

SEND(3PVM)							  PVM Version 3.4							SEND(3PVM)

NAME

       pvm_send - Immediately sends the data in the active message buffer.

SYNOPSIS

       C    int info = pvm_send( int tid, int msgtag )

       Fortran	 call pvmfsend( tid, msgtag, info )

PARAMETERS

       tid     Integer task identifier of destination process.

       msgtag  Integer message tag supplied by the user.  msgtag should be >= 0.

       info    Integer status code returned by the routine.

DESCRIPTION

       The  routine  pvm_send  sends a message stored in the active send buffer to the PVM process identified by tid.  msgtag is used to label the
       content of the message.	If pvm_send is successful, info will be 0. If some error occurs then info will be < 0.

       The pvm_send routine is asynchronous.  Computation on the sending processor resumes as soon as the message is safely  on  its  way  to  the
       receiving  processor.   This is in contrast to synchronous communication, during which computation on the sending processor halts until the
       matching receive is executed by the receiving processor.

       The PVM model guarantees the following about message order.  If task 1 sends message A to task 2, then task 1 sends message B  to  task	2,
       message	A will arrive at task 2 before message B.  Moreover, if both messages arrive before task 2 does a receive, then a wildcard receive
       will always return message A.

       Terminating a PVM task immediately after sending a message or messages from it may result in those messages being lost.	To be sure, always
       call pvm_exit() before stopping.

EXAMPLES

       C:
	    info = pvm_initsend( PvmDataDefault );
	    info = pvm_pkint( array, 10, 1 );
	    msgtag = 3 ;
	    info = pvm_send( tid, msgtag );

       Fortran:
	    CALL PVMFINITSEND(PVMRAW, INFO)
	    CALL PVMFPACK( REAL8, DATA, 100, 1, INFO )
	    CALL PVMFSEND( TID, 3, INFO )

ERRORS

       These error conditions can be returned by pvm_send

       PvmBadParam
	      giving an invalid tid or a msgtag.

       PvmSysErr
	      pvmd not responding.

       PvmNoBuf
	      no active send buffer. Try pvm_initsend() before send.
