pyscripting Description

Shell scripting library for Python pyscripting is Python module that provides various utilities to make shell scripting with python easier.Getting started Get scripting.py: pip install pyscripting Create your python shell script myscript.py: #!/usr/bin/env python from scripting import sh sh.ls('-l') Use your script: chmod +x myscript.py ./myscript.pyCalling external commandsThere are three ways to call external commands.If possible, python replacement of an external command will be used. Replacements will not be used only in direct calling.For all replaced commands see Replaced commands.Direct callingReturns exit code.sh('ls', '-l')Indirect callingReturns exit code.sh.ls('-l')Call and return outputReturns stripped stdout (stderr will not be included).Using this method, output of command will not be printed to stdout. Before returning output, leading white spaces will be stripped.Don't use this methos for large outputs.output = sh.get('ls', '-l')print('Output was: %s' % output)Argument handlingYou can access arguments passed to script using argv property:sh.argv - called script namesh.argv - first argumentReplaced commandsTo avoid overhead and for simplicity reasons, some external commands was replaced by python's internal functions, which works much faster, that calling external command.basename Same as external basename. Returns string.exit Same as external exit.find Similar to external find command. Returns iterator of all found files. Example usage: for f in sh.find(type='f', exclude=): print(f)mkdir Same as external mkdir.mkdirs Same as external mkdir -p.test Similar to external test. Returns boolean. Example usage: if sh.test('-d', '/tmp'): print('/tmp is directory.')Makefile functionalityExample (myscript.py):#!/usr/bin/env pythonfrom scripting import sh, Makefilemake = Makefile(sh)@make('/tmp/myfile.txt')def myrule(target): sh.touch(target)@make()def main(target): myrule()make.run(main)Last line make.run(main) checks sys.argv and executes specified rule or default if no particular rule is specified. myrule will be executed only, if target file /tmp/myfile.txt does not exists.:./myscript.pyNow call particular rule:./myscript.py myrule Requirements: · Python
