[SOLVED] system() and gzip

[bucky4]

I am trying to call gzip inside my c prog in Ubuntu with the system() function :
system( "gzip file.dds" );

But nothing happens!The file is present in the current directory, and system() returns 0.
If I call system( "gzip -h" ) instead, it does print the help message as intended.
If I type the command by hand in the shell, it works.
Same problem with zip : system( "zip tmp.zip file.dds" );

Any idea somebody?
Thanks.

try something like:

system("gzip '/home/share/test/filename'");


hope this helps...Gerard4143

Thanks for the answer Gerard, but still the same.
I also tried to chmod 777 everything.
It does not seem to be due to permissions.

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char**argv)
{
	system("gzip 'filename'");
	exit(EXIT_SUCCESS);	
}

this is the code I used, both on Puppy Linux and Suse 11.0, and it worked with no problems

Ok, found my bug from your simplified code.
I was building a command string with sprintf(), but passing system( "command" ), instead of system( command ).
Isn't that great after a quarter century programming in C/C++ !
Thanks again for your help.
