popen truncates the command line passed to it

********************************
Following is not the real issue. The issue is with popen.
Plz continue forward with the thread to get a better picture.

Hi,

I am working on a customised ftp application. In it we have used sprintf to store a UNIX command like "ls *test" to a temporary variable to execute it on the server and return the result to the client. However the sprintf and snprintf is not working properly. The following code segment will give an idea.

--------------------------
char name[] = "*test";
char cmd[] = "/bin/ls -l %s";
char line[1024];

sprintf (line, cmd, name);
---------------------------
After sprintf the
expected result is,
line = "/bin/ls -l *test"

but what we are getting is,
line = "/bin/ls"
----------------

Can anyone tell me what is wrong with the code? I will be highly indebted.

Regards,
Diganta
