I m trying to write a %pre script in python to backup my ssh keys and cfengine keys in pre script and to put them back in place in post script. I am a total python novice as i use usually perl which is not available. i have written a script but i used a function that is not available in the %pre section it s the glob function. the instruction is nomfichiers = glob.glob("/proc/ide/h*") Does someone know howi can do the same thing that will be acceptable in %pre script? Is the string library available too? Thanks in advance for any help P.S I will publish my script on this list when it works :) -- Eric Doutreleau I.N.T | Tel : +33 (0) 160764687 9 rue Charles Fourier | Fax : +33 (0) 160764321 91011 Evry France | email : Eric.Doutreleau@xxxxxxxxxxx
