CFD Online Discussion Forums - An interesting point about permission denied error!!! help me

Hi everybody

an interesting thing happen for me is that I ran a case with buoyantBoussinesqSimpleFoam solver in parallel with the following code in my Allrun file:

Code:

#!/bin/sh

cd ${0%/*} || exit 1    # run from this directory



# Source tutorial run functions

. $WM_PROJECT_DIR/bin/tools/RunFunctions



application=`getApplication`



#runApplication $application

runApplication decomposePar

runParallel $application 3

runApplication reconstructPar

streamFunction

foamToTecplot360



# ----------------------------------------------------------------- end-of-file

It successfully solved my problem.

then I copied this case to my external hard disk and deleted the case from first place. then I copied the case from my external hard disk to my system exactly where the previous case was in it.
I ran it again with ./Allrun but it said:

Code:

bash: ./Allrun: Permission denied

any body knows where is the problem? I'm so confused.

thanks
Mostafa
