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:
Code:
PATH=$PATH:/home/ehsan/Desktop/codes
other scripts are working well but plot doesn't by this error:
Code:
ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ plot rhoCentralFoam
plot: rhoCentralFoam: No such file or directory
plot: ignoring this file
(for example report file performs fine but plot doesn't)
Attached Files
File Type: gz plot.tar.gz (207 Bytes, 7 views)
File Type: gz report.tar.gz (169 Bytes, 3 views)

Try to use the export command in .bashrc to make the variable global:
Code:
export PATH="$PATH:/home/ehsan/Desktop/codes"

In the top of your plot script, you have the shebang:
Code:
#! /bin/sh
try to remove the space, such that it become
Code:
#!/bin/sh
Also make sure that you have made the script executable, by calling
Code:
chmod +x plot
from the folder with the plot script.

Greetings to all!

@Ehsan: What happens if you run the contents of the script directly on the command line? Namely:
Code:
pyFoamPlotRunner.py --hardcopy --with-courant --progress --no-pickled-file rhoCentralFoam
Best regards,
Bruno

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:
Code:
#!/bin/sh
To:
Code:
#!/bin/bash
If it still doesn't work, try:
Code:
#!/bin/bash
which $1
It should tell you where rhoCentralFoam is located, namely it should give the same as running on the command line:
Code:
which rhoCentralFoam

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

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

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:
Code:
#!/bin/bash -x
It should show you what it's doing when the script is executed.

that says this:
Code:
ehsan@Ehsan-com:~/Desktop/WR_Main_Central$ runPlot rhoCentralFoam
+ solver=rhoCentralFoam
+ pyFoamPlotRunner.py --hardcopy --with-courant --progress --no-pickled-file rhoCentralFoam

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