I have a Python code that will run a script file.The script file will output the version tag of specific git repository.
My script file named 'start.sh' is as follows:
#!/bin/sh
git clone https://xxxxxxxxxx:x-oauth-basic#github.com/xxxxxxx/xxxxx.git
cd xxxxxxxx
git config --global user.email "xxxxxxxx"
git config --global user.name "xxxxxxxxx"
IMAGE_TAG=`echo \`git describe --tags\``
echo $IMAGE_TAG
My Python code is as follows:
import os
git_tag = os.popen('sh start.sh')
print(git_tag)
When I run the script file separately, it will return me the git tag. But, Whenever I try to print it in the Python code, it's not working.
How can I solve this issue?
Since you are using Python anyway, you could think of using GitPython as an alternative. You can list all your tags with:
from git import Repo
repo = Repo("path/to/repo")
print(repo.tags)
Try like this
from subprocess import check_output
out = check_output(['sh', 'start.sh'])
print(out)
According to python's documentation, os.popen() function has been deprecated since version 2.6. You might want to use subprocess module.
P.S: I wanted to comment but couldn't hence this answer.
For python3-X:
from subprocess
git_tag = subprocess.run(['sh', 'start.sh'], capture_output=True, text=True)
print(git_tag.stdout)

I have a python script.
I need to access the name of the git branch from which I'm running the python script, through python, during runtime.
Is there a way to do this?
Edit:
os.system("git rev-parse --abbrev-ref HEAD") outputs to the cli, I don't see how I would get access to it from python...
I would like to have sth like git_branch = <python commands>
You could use GitPython, something like the following:
>>> import git
>>> import os
>>> git_branch = git.Repo(os.getcwd()).active_branch.name
>>> git_branch
'master'
Otherwise, as already pointed out by Yevhen Kuzmovych in the comments, you could use PyGit.
I can use "nginx -s reload" command to restart nginx on the shell.
But, when I use os.system("nginx -s reload") command, It appears error.
/usr/local/bin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
For this error. I already install pcre. Is there some magic problems.
For running such commands in python scripts it's better to use subprocess library.
try this code instead of yours:
import subprocess
subprocess.call('whatever command you want to run it in terminal', shell=True)
Be lucky
hello I recommend that you first send this validation before sending the reset so you avoid headaches
reinicioNGINX = subprocess.getoutput(['nginx -t'])
if 'nginx: the configuration file /etc/nginx/nginx.conf syntax is ok' in reinicioNGINX:
_command_restart
else:
_command_avoid_restart
I source a dotcshrc file in my python script with :os.system(‘/bin/csh dotcshrc’) and it works,but when I want to use the command I have just put into the env by the source command,like os.system(‘ikvalidate mycase ‘),linux complaints:command not found.
But when I do it all by hand,everything go well.
Where is problem?
If you have a command in linux like ls and you want to use it in your python code do like this:
import os
ls = lambda : os.system('ls')
# This effectively turns that command into a python function.
ls() # skadoosh!
Output is :

os.system runs each command in its own isolated environment. If you are sourcing something in an os.system call, subsequent calls will not see that because they are starting with a fresh shell environment. If you have dependencies like the above, you might be able to combine it into one call:
os.system(‘/bin/csh "dotcshrc; ikvalidate mycase"’)
I'm converting a Bash script to Python. I have been looking for a replacement for the "make install" - line. Is there any?
print "Installing from the sources"
urllib.urlretrieve("http://"+backupserver+"/backup-manager.tar.gz","backup-manager.tar.gz")
tar = tarfile.open("backup-manager.tar.gz", "r:gz")
tar.extractall()
tar.close()
os.chdir("Backup-Manager-0.7.10")
make install
import subprocess
subprocess.call(['make', 'install'])
Should do the trick.
If you want the output look at this
You can use subprocess
or else
import os
os.system("make install")

I want to execute git command in python program.
I have tried
os.system("git-command")
As we know, git command can be executed correctly only in the directories which contains repositories. I have tried to print current path and this path is not what I hope for, it does not contains repositories.
Now my question is how to execute git command in a identified path.
Use the subprocess module; pick one of the functions that suits your needs (based on what output you need). The functions all take a cwd argument that lets you specify the directory to operate in:
import subprocess
output = subprocess.check_output(['git', 'status'], cwd='/path/to/git/workingdir')
Using GitPython:
from git import *
repo = Repo("/path/to/repo")
git = repo.git
print git.status()
