如何在bash脚本中包含python脚本

我需要在bash脚本中包括以下python脚本。

如果bash脚本成功结束，则需要执行以下脚本：

#!/usr/bin/python    
from smtplib import SMTP
import datetime
debuglevel = 0

smtp = SMTP()
smtp.set_debuglevel(debuglevel)
smtp.connect('192.168.75.1', 25)
smtp.login('my_mail', 'mail_passwd')

from_addr = "My Name <my_mail@192.168.75.1>"
to_addr = "<my_mail@192.168.75.1"
subj = "Process completed"
date = datetime.datetime.now().strftime( "%d/%m/%Y %H:%M" )
#print (date)
message_text = "Hai..\n\nThe process completed."

msg = "From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s" % ( from_addr, to_addr, subj, date, message_text )

smtp.sendmail(from_addr, to_addr, msg)
smtp.quit()

如果要将bash和python脚本的源代码放在一起，可以使用heredoc。例如，说下面是一个名为的文件的内容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

现在运行pyinbash.sh将产生：

$ chmod 755 pyinbash.sh
$ ./pyinbash.sh
Exe

只需将HereDoc传递给即可python -。

从python帮助python -h：

- : program read from stdin

#!/bin/bash

MYSTRING="Do something in bash"
echo $MYSTRING

python - << EOF
myPyString = "Do something on python"
print myPyString

EOF

echo "Back to bash"

最简单的方法是例如仅将python脚本另存为，script.py然后从bash脚本调用它，或者在bash脚本之后调用它：

#!/usr/bin/env bash
echo "This is the bash script" &&
/path/to/script.py

要么

script.sh && script.py

举个例子：

PYTHON_BIN=/usr/bin/python
if [ -x $PYTHON_BIN ]; then
$PYTHON_BIN -c "print 'Hello, world'"
else
echo 'Hello, world'
fi

VS

$ ./foobar.py
env: python: No such file or directory
