OS command via python subprocess module

[Gribouillis]

I recently came across a nice way to convert such scripts: the plumbum module. Using this module, your python code could more or less resemble the following

from plumbum import local, cmd
ORACLE_HOME = local.env['ORACLE_HOME']
local.env['PATH'] = "{ohome}/bin:{ohome}/OPatch:{path}".format(
    ohome=ORACLE_HOME, path=local.env[PATH])
local.cwd.chdir(ORACLE_HOME)
cmd.mv('OPatch', 'OPatch.pre6880880')
cmd.mkdir('OPatch')

osTyp = cmd.uname('-s').strip()
if osTyp == 'Linux':
    cmd.cp(
        "/gfd/infr/DBA/oracle12102-Linux-X86-64/6880880_zipDir/p6880880_122010_Linux-x86-64.zip", ".")
    cmd.unzip("p6880880_122010_Linux-x86-64.zip")
elif osTyp == 'SunOs':
    cmd.cp("/gfd/infr/DBA/oracle12102-Solaris64/6880880_zipDir/p6880880_122010_SOLARIS64.zip", ".") 
    cmd.unzip("p6880880_122010_SOLARIS64.zip") 
else
    print("!!\n!! unable to determine OS type !!\n!!")
