Hello,

I am new at these topics and i am trying to upload a file with cgi. I have an html code like below :

<table class=upload>
<form method='POST' enctype='multipart/form-data' action='upload.cgi'>
<input name=upfile type=file ><br>
<br> <input type=submit value=Press> to upload the file!</form>
</table><br>

I am trying to get the file with upload.cgi and execute a linux command in linux but i do not know how to. I use C code for that. Can you help me,please? How can i know the file from html in cgi C code?

With C, I recommend using the qDecoder (version 11 or later, as the API has changed a bit). They have a working file upload example, uploadfile.c. I recommend starting with that one since it streams the uploaded files directly to disk, and therefore uses much less memory on the server. The other example, upload.c, reads the file(s) into RAM first.
