From this stackoverflow thread https://stackoverflow.com/questions/4443...mmand-line, I have extracted this command line:
gimp-console -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.run('./images')" -b "pdb.gimp_quit(1)"
It works perfectly well.
Now, I would like to run this command from a Python script, usually I use subprocess.Popen but this time it does not work and I get this message:
"batch command experienced an execution error"
How can I launch the GIMP command line from a Python script?
One easy way to resolve this is to just put your GIMP startup script into a bash script, say startgimp.sh
#!/bin/bash
#set your path to GIMP or cd into the folder where you installed GIMP
gimp-console -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.run('./images')" -b "pdb.gimp_quit(1)"
then from Python simply call the bash script like so
import subprocess
subprocess.call(["bash","/path/to/your/script/startgimp.sh"])
If you are able to make the .sh script executable, e.g. chmod +x startgimp.sh then you can skip the bash part and just do subprocess.call("/path/to/your/script/startgimp.sh")
Some caveats
This is assuming you're on a UNIX based system
I used subprocess.call so this WILL block while waiting for GIMP to complete. Use Popen like you've used if you don't want this
I don't have GIMP to try this out, but you could also try splitting your GIMP command into elements in the list and pass it to subprocess and see if that works.
e.g. subprocess.call(["gimp-console","-idf","--batch-interpreter","python-fu-eval" and so on)

I have a command in my bash_profile such as id=12345 which I defined the following alias
alias obs="echo $id" since the id will chance over time.
Now what I want to do is call this alias in my python script for different purposes. My default shell is bash so I have tried the following based on the suggestions on the web
import subprocess
subprocess.call('obs', shell=True, executable='/bin/bash')
subprocess.call(['/bin/bash', '-i', '-c', obs])
subprocess.Popen('obs', shell=True,executable='/bin/bash')
subprocess.Popen(['/bin/bash', '-c','-i', obs])
However, none of them seems to work! What am I doing wrong!
.bash_profile is not read by Popen and friends.
Environment variables are available for your script, though (via os.environ).
You can use export in your Bash shell to export a value as an environment variable, or use env:
export MY_SPECIAL_VALUE=12345
python -c "import os; print(os.environ['MY_SPECIAL_VALUE'])"
# or
env MY_SPECIAL_VALUE=12345 python -c "import os; print(os.environ['MY_SPECIAL_VALUE'])"
I'm trying to execute a shell command using Python's subprocess. This is how I do it:
pelican = 'pelican content -s /home/pelican/publishconf.pyt -D --ignore-cache'
subprocess.call(pelican, shell=True)
But the response is command not found. It doesn't have a problem when I write in my command line.
My question is how can I execute a shell command using python that behaves just like I would type it in?
I would like to submit Python scripts directly on a computing cluster using SGE. I have a test script:
#!/usr/bin/python
print "hello"
I have run chmod +x hello.py such that on the front end:
./hello.py
>> hello
However, when I run qsub -o out.log hello.py, the following files are generated:
out.log:
Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.
hello.py.e707589:
print: Command not found.
It seems to me that qsub is nonetheless trying to interpret the script as a bash script, even despite the header. How can I fix this?
I want to run a python script on boot of ubuntu 14.04LTS.
My rc.local file is as follows:
sudo /home/hduser/morey/zookeeper-3.3.6/bin/zkServer.sh start
echo "test" > /home/hduser/test3
sudo /home/hduser/morey/kafka/bin/kafka-server-start.sh /home/hduser/morey/kafka/config/server.properties &
echo "test" > /home/hduser/test1
/usr/bin/python /home/hduser/morey/kafka/automate.py &
echo "test" > /home/hduser/test2
exit 0
everything except my python script is working fine even the echo statement after running the python script, but the python script doesnt seem to run.
My python script is as follows
import sys
from subprocess import Popen, PIPE, STDOUT
cmd = ["sudo", "./sbt", "project java-examples", "run"]
proc = Popen(cmd, shell=False, stdout=PIPE, stdin=PIPE, stderr=STDOUT)
proc.communicate(input='1\n')
proc.stdin.close()
which works perfectly fine if executed individually.
I went through the following questions , link
I did a lot of research but couldn't find a solution
Edit : echo statements are for testing purpose only, and the second actual command (not considering the echo statements) is starting a server which keeps on running, and even the python script starts a listener which runs on an infinite loop, if this is any help
The Python script tries to launch ./sbt. Are you sure of what if the current directory when rc.local runs? The rule is always use absolute paths in system scripts
Do not run the Python script in background, run it in foreground. Do not exit from its parent script. Better call another script from "rc.local" that does all the job of "echo" and script launching.
Run that script from "rc.local"; not in background (no &).
You do not need "sudo" as "rc.local" is run as root.
If you want to run python script at system boot there is an alternate solution which i have used.
1:Create sh file like sample.sh and copy paste following content
#!/bin/bash
clear
python yourscript.py
2:Now add a cron job at reboot.If you are using linux you can use as following
a:Run crontab -e(Install sudo apt-get install cron)
b:#reboot /full path to sh file > /home/path/error.log 2>&1
And restart your device
I use python module pysftp to connect to remote server. Below you can see python code :
import pysftp
import sys
import sqr_common
srv = pysftp.Connection(host="xxxxxx", username="xxxx",
password="xxxxx")
command = "/usr/bin/bash"
command2="APSHOME=/all/aps/msc_2012; export APSHOME; "
srv.execute(command)
srv.execute(command2)
srv.close()
Problem is that command /usr/bin/bash is an infinite process , so my script will never be executed. Can anyone help me how to choose shell on remote server for example bash and execute command in bash on remote server?? Is there any pysftp function that allows me chosing shell??
try this
/usr/bin/bash -c "APSHOME=/all/aps/msc_2012; export APSHOME; "
This problem is not specific to Python, but more like how to execute commands under specific shell.
If you need to run only single command you can run using bash -c switch
bash -c "echo 123"
You can run multiple commands ; separated
bash -c "echo 123 ; echo 246"
If you need to many commands under a specific shell, remotely create a shell script file (.bash file) an execute it
bash myscript.bash
