The problem is , when i'am using python to execute that command line



  os.system("sudo -u "+self.user+" printf "+ self.data +"  > "+ self.path)


is updating the file with new data but not with variables just with space
example



<?php
$test = "dddd";
echo "please work".$test;


will be after execute command line to



<?php
= "dddd";
echo "please work".;


without variables
So how can i solve this problem ?

  • You should surround with a single quote: os.system("..." + "printf '" + self.data + "' > .." (Note the single quote). Also, you wouldn't have run into this issue had you used Popen with a list argument instead of os.system(..).
