I'm using subprocess within a python script to send variables into a bash script which is designed to send emails.
My python code:
import re
import subprocess
message="https://example.com/"
subprocess.run(["./send_email.bash",message])
My "./send_email.bash" script:
#!/bin/bash
body=$1
echo "$body" | ssmtp example#gmail.com
It keeps sending a blank email. However, if I use a string which doesn't come from subprocess, the email contains it. There may be a better way of doing this, but the point of my post is to understand why this doesn't work. What perplexes me is that the variable sent from subprocess may be appended to a file. But, it cannot be recognized by loops or "if" expressions. etc.
Thank you!
I should have been more specific. The "message" within my python code was an email address: "https://example.com/". It appears that when I remove the "https://" from the string, it works perfectly fine!

I am trying to trigger the python script or shell script whenever a desktop notification has arrived using dbus-monitor
I am using the command in this way
dbus-monitor "interface='org.freedesktop.Notifications'" | grep --line-buffered "string" | xargs -I '{}' python3 ./test.py {}
after that, I am trying to send the desktop notification from another terminal using
-> notify-send "hello" "world"
the output for the above custom notification is
string "notify-send"
string ""
string "hello"
string "world "
string "urgency"
string "notify-send"
string ""
string "hello"
string "world "
string "urgency"
but if my output of this command is 10 lines, then the python script is getting called for every line.
but my expectation is to call the python script once for every notification and then get all the output in a single line as a param for the python script.
It is wise to take advantage of systemd integration with dbus.
Using systemd integration the programmer has better controls/sensors over the dbus integration. Also can take advantage on systemd loging/monitors mechanisms.
There is a good article here about systemd dbus with python..
Also there is very related answer to your question in this answer. as well.
I have a python script that successfully sends SOAP to insert a record into a system. The values are static in the test. I need to make the value dynamic/argument that is passed through the command line or other stored value.
execute: python myscript.py
<d4p1:Address>MainStreet</d4p1:Address> ....this works to add hard coded "MainStreet"
execute: python myscript.py MainStreet
...this is now trying to pass the argument MainStreet
<d4p1:Address>sys.argv[1]</d4p1:Address> ....this does not work
It saves the literal text address as "sys.argv[1]" ... I have imported sys ..I have tried %, {}, etc from web searches, what syntax am I missing??
You need to read a little about how to create strings in Python, below is how it could look like in your code. Sorry it's hard to say more without seeing your actual code. And you actually shouldn't create XMLs like that, you should use for instance xml module from standard library.
test = "<d4p1:Address>" + sys.argv[1] + "</d4p1:Address>"
I need to check GoldenGate processes' lag. In order to this, I execute Goldengate than I try to run GoldenGate's own commands "info all".
import subprocess as sub
import re
import os
location = str(sub.check_output(['ps -ef | grep mgr'], shell = True)).split()
pattern = re.compile(r'mgr\.prm$')
print(type(location))
for index in location:
if pattern.search(index)!=None:
gg_location = index[:-14] + "ggsci"
exec_ggate = sub.call(str(gg_location))
os.system('info all')
Yet, when I execute the GoldenGate it opens a new GoldenGate's own shell. So, I think because of that, Python cannot be able to do run "info all" command. How can I solve this problem? If there is missing information, please inform me.
Thank you in advance,
For command automation on Golden Gate you have the following information in the Oracle docs: https://docs.oracle.com/goldengate/1212/gg-winux/GWUAD/wu_gettingstarted.htm#GWUAD1096
To input a script
Use the following syntax from the command line of the operating system.
ggsci < input_file
Where:
The angle bracket (<) character pipes the file into the GGSCI program.
input_file is a text file, known as an OBEY file, containing the commands that you want to issue, in the order, they are to be issued.
Taking your script (keep into mind I don't know to code into python) you can simply execute a shell command in python in the following way:
import os
os.system("command")
So try doing this:
import os
os.system("ggsci < input_file")
Changing the input_file as indicated by the docs.
I think you will have an easier time doing it this way.
I need to extract text from a PDF. I tried the PyPDF2, but the textExtract method returned an encrypted text, even though the pdf is not encrypted acoording to the isEncrypted method.
So I moved on to trying accessing a program that does the job from the command prompt, so I could call it from python with the subprocess module. I found this program called textExtract, which did the job I wanted with the following command line on cmd:
"textextract.exe" "download.pdf" /to "download.txt"
However, when I tried running it with subprocess I couldn't get a 0 return code.
Here is the code I tried:
textextract = shlex.split(r'"textextract.exe" "download.pdf" /to "download.txt"')
subprocess.run(textextract)
I already tried it with shell=True, but it didn't work.
Can anyone help me?
I was able to get the following script to work from the command line after installing the PDF2Text Pilot application you're trying to use:
import shlex
import subprocess
args = shlex.split(r'"textextract.exe" "download.pdf" /to "download.txt"')
print('args:', args)
subprocess.run(args)
Sample screen output of running it from a command line session:
> C:\Python3\python run-textextract.py
args: ['textextract.exe', 'download.pdf', '/to', 'download.txt']
Progress:
Text from "download.pdf" has been successfully extracted...
Text extraction has been completed!
The above output was generated using Python 3.7.0.
I don't know if your use of spyder on anaconda affects things or not since I'm not familiar with it/them. If you continue to have problems with this, then, if it's possible, I suggest you see if you can get things working directly—i.e. running the the Python interpreter on the script manually from the command line similar to what's shown above. If that works, but using spyder doesn't, then you'll at least know the cause of the problem.
There's no need to build a string of quoted strings and then parse that back out to a list of strings. Just create a list and pass that:
command=["textextract.exe", "download.pdf", "/to", "download.txt"]
subprocess.run(command)
All that shlex.split is doing is creating a list by removing all of the quotes you had to add when creating the string in the first place. That's an extra step that provides no value over just creating the list yourself.
I'm building a data loggerr and I've spent a lot of time trying to get this right, every forum takes me in a different direction and I think a weekend of googling warrants submitting a question here.
I'm running Ubuntu 12.10, I use fetchmail to get my mail, it sends it to procmail, and I have procmail piping it to a python script that is supposed to parse the body, and save it to a text file. The problem is I can't figure out how to write a python script that will do this, every example I find online is a bit over my head and I was hoping someone could take a little time to help me understand how this could be accomplished.
In .promailrc, use the following recipe to pipe all emails into the python script:
:0Wc:
| /usr/bin/python [PATH TO PYTHON SCRIPT]
In the python script you can receive the incoming email using:
import sys
import email
full_msg = sys.stdin.readlines()
msg = email.message_from_string(full_msg.join());
to = msg['to']
from = msg['from']
subject = msg['subject']
body = msg['body']
