Plumbum Shell Combinators
|
|
-------------------------
|
|
A wrist-handy library for writing shell-like scripts in Python, that can serve
|
|
as a ``Popen`` replacement, and much more::
|
|
|
|
>>> from plumbum.cmd import ls, grep, wc, cat
|
|
>>> ls()
|
|
'build.py\ndist\ndocs\nLICENSE\nplumbum\nREADME.rst\nsetup.py\ntests\ntodo.txt\n'
|
|
>>> chain = ls["-a"] | grep["-v", "py"] | wc["-l"]
|
|
>>> print(chain)
|
|
/bin/ls -a | /bin/grep -v py | /usr/bin/wc -l
|
|
>>> chain()
|
|
'12\n'
|
|
>>> ((ls["-a"] | grep["-v", "py"]) > "/tmp/foo.txt")()
|
|
''
|
|
>>> ((cat < "/tmp/foo.txt") | wc["-l"])()
|
|
'12\n'
|
|
>>> from plumbum import local, FG, BG
|
|
>>> with local.cwd("/tmp"):
|
|
... (ls | wc["-l"]) & FG
|
|
...
|
|
13 # printed directly to the interpreter's stdout
|
|
>>> (ls | wc["-l"]) & BG
|
|
<Future ['/usr/bin/wc', '-l'] (running)>
|
|
>>> f = _
|
|
>>> f.stdout # will wait for the process to terminate
|
|
'9\n'
|
|
|
|
Plumbum includes local/remote path abstraction, working directory and environment
|
|
manipulation, process execution, remote process execution over SSH, tunneling,
|
|
SCP-based upload/download, and a {arg|opt}parse replacement for the easy creation
|
|
of command-line interface (CLI) programs.
|
|
|
|
