I use: exec("split --suffix-length=4 --numeric-suffixes --bytes=${SIZE} ${FILE} UPLOAD_0"); exec("md5sum UPLOAD_0* >UPLOAD_md5sums); ... /* upload a file and receive a cookie */ exec("wget --save-cookies=UPLOAD_cookies --http-user=${user} --http-password=${password} --post-file=UPLOAD_0${CHUNK} ${URL}"); /* use the cookie to get the status of the next file */ exec("wget --load-cookies=UPLOAD_cookies --http-user=${user} --http-password=${password} ${URL}"); ...
