Hi ..

I have a doubt plz clarify this...

I wrote a daemon in c which uses wget command to run a php file, this php file( let be xx.php) does some process to insert a node in an XML file. While executing the daemon it is working perfectly..i.e inserting data accurately but it is creating some files naming as xx.php.1,xx.php.2 e.t.c..I dont know whether it happens so plz help me and post if their is any solution to stop that backup's i dont know whether we have to call it as backups or not coz those are simply empty files...

wget is a tool to download files by http or ftp. If the file (actually : the file name of that file) you download already exists in the location you download it to, wget will by default create a copy and add numbers to the filename. I suspect those are the .php.2, php.3 ... your seeing.

Sollution : your program could check if the file already exist (so wget does not need to download it again,), You can also run wget with options -N -nc or -r to prevent the numbered copies (see man wget) : wget will then either not download or download and overwrite the existing file.

I'm not sure this is in fact the problem, because i don't really understand what your program is doing, but it looks like typical wget behaviour so it's worth a shot.
