I have a simple docker container that is based on windows image:
FROM mcr.microsoft.com/windows:1903
WORKDIR /app1/
ENTRYPOINT powershell.exe
I run it interactively, using:
docker run -it -v c:\app1:c:\app1 test-image:1.0
There is a file called 1.txt inside app1 folder.
When I run:
.\app1\1.txt
I see no notepad.exe process, but instead I can spot OpenWith process:

I suspect that some mapping might be missing, event though assoc shows that .txt file is associated with notepad.exe:
assoc .txt
.txt=txtfile
ftype txtfile
txtfile=%SystemRoot%\system32\NOTEPAD.EXE %1
What might be the problem here? Am I missing some register value?

You can check the BrowserStackLocal.exe was downloaded successfully in the log, also I tried executing the same file in machines in Windows and it's working fine. The problem only happened when I run inside the docker windows container.
Maybe some DLL files are missing or I need to install anything else. Do you have any idea to resolve this? or any workaround?
Thank you in advance.
Problem
I'm running an executable cp2k installed on HPC cluster using mpich-3.2. The output from the executable is printed in an out file. The problem is, that there is no output in the out file after some steps are printed, but when I see the status of my job on the cluster, it turns out that it is still running. Basically, the problem is that my job is still running, but the output is not getting printed.
Script
I'm using the following job script:
#!/bin/bash
#PBS -N test
#PBS -o test.log
#PBS -j oe
#PBS -l nodes=2:ppn=20
#PBS -q mini
#PBS -l walltime=2:00:00
cd $PBS_O_WORKDIR
echo Master process running on `hostname`
echo Directory is `pwd`
echo PBS has allocated the following nodes:
echo `cat $PBS_NBODEFILE`
NPROCS=`wc -l < $PBS_NODEFILE`
echo This job has allocated $NPROCS nodes
export I_MPI_FABRICS=shm:dapl
export I_MPI_PROVIDER=psm2
export I_MPI_FALLBACK=0
export KMP_AFFINITY=verbose,scatter
export OMP_NUM_THREADS=1
export I_MPI_IFACE=ib0
echo Starting executation at `date`
EXEC="/home/arshil/software/cp2k-5.1.0/exe/local/cp2k.popt"
cp $EXEC ./cp2k
mpiexec -np $NPROCS --machinefile $PBS_NODEFILE ./cp2k -i test.inp >& out
rm cp2k
echo Finished at `date`
Error
The ouput in the out file:
SCF WAVEFUNCTION OPTIMIZATION

3 OT DIIS 0.80E-01 10.8 0.00001688 -8797.2073257531 -1.14E-03
As it can be seen, there is no printing after step 3 in the output file, but the job is still running in the background. Even after the walltime is over, the output file remains the same as above. Where is the output going?
The executable cp2k is used to perform quantum chemical calculations and was installed on the cluster along with mpich-3.2. All CP2K needs is an input file with extension .inp. For my case, test.inp is the input file.

The problem in my opinion is not with the input file. It has got to do something with mpich-3.2. I would really appreciate some help.
This may be something similar going on / solutions that can be used here: Python "print" not working when embedded into MPI program It is not perfect as you are not using python however it may help.
At a basic level MPI launches many processes - but only the command that launches it has access to stdio etc. The redirect at the end of the line starting with mpiexec sends the stdout of mpiexec to a file. The output from your script is buffered by mpiexec until the processes end (either they complete or they are stopped).
Where the output is going is a good question and may require changes in test.np or some other way of shutting down (you mention you were out of wall time). I'm looking to solve the same problem - and will update this (if) I find an answer.
Also the output from different processes started by mpi can arrive in random order. I do not care about this but if you do you may need to pass the messages back to some common thread which sorts their order.
I have a blastn output file with tens of thousands of rows. I'm only interested in rows where part of the query sequence ID does not match with part of the subject sequence ID, which I'd like to put into a new text file. Here is an excerpt of the massive output file for which I want to extract information from, as an example:

qseqid = query sequence ID
sseqid = subject sequence ID
What should be matching is the OFAS#-RA-EXON# between the two ID's for each row. When this isn't the case, e.g., the 4th and 5th row, I want to extract the entire row and place into a new text file. I know some regex pattern will need to be employed, but how to indicate columns and search on a per row basis isn't clear to me.
This will work with GNU Awk :
tail -n+2 input.txt | awk '{ if( substr($1,0,21) != substr($5,0,21)) { print $0 } }'

I do not want to wait for Oracle DataDump expdb to finish writing to dump file.
So I start reading data from the moment it's created.
Then I write this data to another file.
It worked ok - file sizes are the same (the one that OracleDump created and the one my data monitoring script created).
But when I run cmp it shows difference in 27 bytes:
cmp -l ora.dmp monitor_10k_rows.dmp

Even if I extract more data the difference is still 27 bytes but different addresses/values:

2674734 0 10
2674740 0 1
2674741 0 104
2674742 0 110
Some writes are the same.
Is there a way know addresses of bytes which will differ?
ls -al ora.dmp
-rw-r--r-- 1 bicadmin bic 2760704 Jun 20 11:09 ora.dmp
python -c 'print 2760704-2674742'
85962
How can update my monitored copy after DataDump updated the original at adress 2674742 using Python for example?
Exact same thing happens if I use COMPRESSION=DATA_ONLY option.
Update: Figured how to sync bytes that differ between 2 files:

The reason I do dmp file monitoring is because it cuts backup time in half.
I have following result while running below powershell command,

Here im trying to calculte the total memory size PM(K) of process(s).i've following line in my ps1 script file
get-process svchost | foreach {$mem=("{0:N2}MB " -f ($_.pm/1mb))}
It gives the output in the following format
17.58MB 4.79MB 6.05MB 9.99MB 35.29MB 9.56MB 8.64MB 7.95MB 1.47MB 3.95MB 2.48MB
but i need total size as a single value like 107.75MB
How to calculate the total used memory size of svchost process ?
Thanks
You can use the Measure-Object cmdlet
$measure = Get-Process svchost | Measure-Object PM -Sum
$mem = ("{0:N2}MB " -f ($measure.sum / 1mb))
Also, you can calculate the total size of the entire collection using the += syntax
$mem = 0
Get-Process svchost | %{$mem += $_.pm}
"{0:N2}MB " -f ($mem/1mb)
