I have put this script (plot)on my desktop as well as some other simple scripts and have given its address to bashrc as below:

PATH=$PATH:/home/ehsan/Desktop/codes

other scripts are working well but plot doesn't by this error:

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ plot rhoCentralFoam
plot: rhoCentralFoam: No such file or directory
plot: ignoring this file

(for example report file performs fine but plot doesn't)

[haakon]

Try to use the export command in .bashrc to make the variable global:

export PATH="$PATH:/home/ehsan/Desktop/codes"

[immortality]

thanks.
but the error is repeated.

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ plot rhoCentralFoam
plot: rhoCentralFoam: No such file or directory
plot: ignoring this file

[haakon]

In the top of your plot script, you have the shebang:

#! /bin/sh

try to remove the space, such that it become

#!/bin/sh

Also make sure that you have made the script executable, by calling

chmod +x plot

from the folder with the plot script.

[immortality]

I removed space.yes its executable.doesn't perform.

Greetings to all!

@Ehsan: What happens if you run the contents of the script directly on the command line? Namely:

pyFoamPlotRunner.py --hardcopy --with-courant --progress --no-pickled-file rhoCentralFoam

Best regards,

dear Bruno I have been using that untill now and thought it will be better to do that by a short command and script but it doesn't work.

Mmm... strange... OK, then try changing the first line:

#!/bin/sh

To:

#!/bin/bash

If it still doesn't work, try:

#!/bin/bash
which $1

It should tell you where rhoCentralFoam is located, namely it should give the same as running on the command line:

which rhoCentralFoam

[immortality]

no.which command doesn't work in script but work in terminal:

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ plot rhoCentralFoam
plot: rhoCentralFoam: No such file or directory
plot: ignoring this file
ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ which rhoCentralFoam
/opt/openfoam220/platforms/linux64GccDPOpt/bin/rhoCentralFoam

[wyldckat]

I finally understand what's happening... try running:

which plot
#or
type plot

It will probably tell you it's located at "/usr/bin/plot"!

The solution is simple: rename your "plot" script!

[immortality]

yes that message was shown.then its name is like other script in ubuntu?
but other names don't work:

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ do rhoCentralFoam
bash: syntax error near unexpected token `do'
ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ runPlot rhoCentralFoam
ehsan@Ehsan-com:~/Desktop/WR_Main_Central$

[wyldckat]

What does the following command output?

which runPlot

[immortality]

it knows the path:

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ which runPlot
/home/ehsan/Desktop/codes/runPlot

but

[wyldckat]

OK, then confirm the contents of the file... I don't know what it looks like at this point.

If it all makes sense, try changing the first line to this:

#!/bin/bash -x

It should show you what it's doing when the script is executed.

[immortality]

that says this:

ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ runPlot rhoCentralFoam
+ solver=rhoCentralFoam
+ pyFoamPlotRunner.py --hardcopy --with-courant --progress --no-pickled-file rhoCentralFoam
Killing PID 14778
 PyFoam WARNING on line 232 of file /usr/local/lib/python2.7/dist-packages/PyFoam/Execution/FoamThread.py : Process 14778 was already dead 
Getting LinuxMem: [Errno 2] No such file or directory: '/proc/14778/status'

[immortality]

resolved!
sorry,i had changed a postProceesing function meanwhile and didn't test full pyFoam command it terminal after that change.
then it must have been resolved when I had changed its header to

#!/bin/bash

but i learned some more things!
now a simple question how can I set number of processors in line like this:
runPlot 4 rhoCentralFoam
what should i replace for 4 in this code? :

#!/bin/bash
solver=$1
pyFoamPlotRunner.py --hardcopy --with-deltat --with-courant --procnr=4 $solver

I guess you haven't studied properly the other script I made for merging data and the studying references I gave... Anyway, it's very simple:

#!/bin/bash
solver=$2
pyFoamPlotRunner.py --hardcopy --with-deltat --with-courant --procnr=$1 $solver
