Chut!
Chut is a small tool to help you to interact with shell pipes and commands.
Basically it will help to write some shell script in python
This is more like a toy than a real tool but… It may be useful sometimes.
It’s tested with and py3.5+:
Full documentation can be found here
Quick quick start
Get the chutify script:
$ wget https://raw.github.com/gawel/chut/master/docs/_static/binaries/chutify $ chmod +x chutify
Write a console script:
$ cat << EOF > myscript.py
from chut import *
__version__ = '0.1'
@console_script
def mycmd(args):
"""Usage: %prog [options] <directory>
Print all chut scripts found in <directory>
Options:
%options
"""
for filename in find('-name *.py') | grep('@console_script'):
print(filename)
EOF
Run chutify in development mode:
$ ./chutify --devel chmod +x bin/mycmd
And use/debug the newly created script:
$ ./bin/mycmd -h
When your script is ready for production then generate the standalone version:
$ ./chutify chmod +x dist/scripts/mycmd
Also have a look at the examples.
Installation
Using pip:
$ pip install chut
This will also install docopt and allow you to use the @console_script decorator.
Another option is to get chutify standalone version:
$ wget https://raw.github.com/gawel/chut/master/docs/_static/binaries/chutify $ chmod +x chutify
Quick start
Import the shell:
>>> import chut as sh
Get a file content if it contains “Chut”:
>>> grep_chut = sh.cat('README.rst') | sh.grep('Chut')
>>> if grep_chut:
... print(grep_chut | sh.head("-n1"))
Chut!
Redirect output to a file:
>>> ret = (grep_chut | sh.head("-n1")) > '/tmp/chut.txt'
>>> ret.succeeded
True
>>> print(sh.cat('/tmp/chut.txt'))
Chut!
Or to stdout:
>>> sh.cat('/tmp/chut.txt') > 1 # doctest: +SKIP
Chut!
Redirect stdout to stderr:
>>> sh.cat('/tmp/chut.txt') > 2 # doctest: +SKIP
Chut!
Run many command with a pool of processes:
>>> [ret.succeeded for ret in sh.ls.map(['.', ['-l', '/tmp']])] [True, True]
Use docopt to write a console script. This script will take an iface as argument and return a code 1 if no address is found:
>>> @sh.console_script
... def got_inet_addr(args):
... """Usage: got_inet_addr <iface>"""
... if sh.ifconfig(args['<iface>']) | sh.grep('inet addr:'):
... return 1
