exec() help

[Seko]

I try to execute command: " cat temp* " inside a c prgram
i try exec with: exec("/bin/ls", "-l",0); it works OK but when i try: exec("/bin/cat", "temp*",0); nothing happens...

what can i do?? which system call should i use

[CyberCoder]

May be try this:

execl("/bin/cat","cat","temp*",0);

the second param must be the name of the command. And "temp*" doesn't mean all files beginning with "temp", it's so only in shell IMHO.

Ok it works that way but i need all files start with temp how can i do this?

[CyberCoder]

you can use system instead of exec* like this:
system("/bin/cat temp*");

hi guys!

system() works for C codes only, right? what is its counterpart for c++? :) Thanks!

C++ is only a bag on the side of C. Anything that works in C will work in C++ (assuming you use the correct namespace for the functions, i.e. you may have to use ::system(...) instead of system(...) if the class you're calling system() from has a member named system() also).
