Summary

A Python wrapper library for subprocess module.

Examples

Execute a command

Sample Code:

from subprocrunner import SubprocessRunner

runner = SubprocessRunner("echo test")
print("command: {:s}".format(runner.command))
print("return code: {:d}".format(runner.run()))
print("stdout: {:s}".format(runner.stdout))

runner = SubprocessRunner("ls __not_exist_dir__")
print("command: {:s}".format(runner.command))
print("return code: {:d}".format(runner.run()))
print("stderr: {:s}".format(runner.stderr))

Output:

command: echo test
return code: 0
stdout: test

command: ls __not_exist_dir__
return code: 2
stderr: ls: cannot access '__not_exist_dir__': No such file or directory

dry run

Sample Code:

from subprocrunner import SubprocessRunner

runner = SubprocessRunner("echo test", dry_run=True)
print("command: {:s}".format(runner.command))
print("return code: {:d}".format(runner.run()))
print("stdout: {:s}".format(runner.stdout))

Output:

command: echo test
return code: 0
stdout:

Get execution command history

Sample Code:

from subprocrunner import SubprocessRunner

SubprocessRunner.clear_history()
SubprocessRunner.is_save_history = True

SubprocessRunner("echo hoge").run()
SubprocessRunner("echo foo").run()

print("\n".join(SubprocessRunner.get_history()))

Output:

echo hoge
echo foo

Get a command information

>>> from subprocrunner import Which
>>> which = Which("ls")
>>> which.is_exist()
True
>>> which.abspath()
'/usr/bin/ls'
>>> which
command=ls, is_exist=True, abspath=/usr/bin/ls
