#!/bin/sh
python disk.py

#!/bin/sh
python disk.pyThe simplest approach is to just save the python script as, for example script.py and then either call it from the bash script, or call it after the bash script:
#!/usr/bin/env bash
echo "This is the bash script" &&
/path/to/script.py
Or
script.sh && script.pyYou can use heredoc if you want to keep the source of both bash and python scripts together. For example, say the following are the contents of a file called pyinbash.sh:
#!/bin/bash
echo "Executing a bash statement"
export bashvar=100
cat << EOF > pyscript.py
#!/usr/bin/python
import subprocess
print 'Hello python'
subprocess.call(["echo","$bashvar"])
EOF
chmod 755 pyscript.py
./pyscript.py
Now running the pyinbash.sh will yield:
$ chmod 755 pyinbash.sh
$ ./pyinbash.sh
Exe#!/bin/bash
/usr/bin/python /absolute/path/to/your/disk.py#!/bin/bash
python3
print("Hello World")
exit()
echo "The execution is completed"*2 Example of the dangers of temp files. DO NOT USE THIS CODE
cat >/tmp/python-script <<END
for i in range(10):
print(i)
END
python /tmp/python-script
If someone else creates /tmp/python-script first, this shell script won't even stop if it fails to overwrite the file. A malicious user on the system could make a harmful Python script which will run instead of the intended script.#!/bin/bash
PYCMD=$(cat <<EOF
from datetime import datetime
first_day_of_new_year = datetime(2022, 1, 1)
days_remaining = (first_day_of_new_year - datetime.now()).days
print('{} days remaining in this year'.format(days_remaining))
EOF
)
python3 -c "$PYCMD"#!/bin/bash
MYSTRING="Do something in bash"
echo $MYSTRING
python - << EOF
myPyString = "Do something on python"
print myPyString
EOF
echo "Back to bash"read -p "How many numbers: " n
python <<END
for i in range($n):
print(i)
print("Literal dollar sign \$")
ENDThere are ways to do this safely, but the simplest way would be to create the files in the current working directory or in a dedicated directory in the home directory.
