from subprocess import Popen, PIPE
target = '~/Library/Preferences/iCab/iCab 4 Bookmarks'
args = ['plutil', '-convert', 'xml1', target]
proc = Popen(args, stdout=PIPE, stderr=PIPE)
output, error_output = proc.communicate()
if proc.returncode: # non-zero exit status, indicating error
print("Encountered error:")
print(error_output) # output the error message
