can you redirect multiple files for input?
I have a program that is reading strings into a vector from a file. Currently I am using this command:

a.out < file1

The program runs and prints the contents of the vector to the screen, like its supposed to. The problem is that it needs to read in 3 files to fill the vector. Is there anyway to do this?

I tried:

a.out < file 1 < file2 This didn't work

I tried

a.out < file1 ; file2 This didn't work

I'm still pretty new to UNIX, so I obviously don't have all the commands down. Can I read in more than one file at a time? If so, how?

(cat file1 file2) | a.out

I just tried that and I got "ambigous redirect"

Any ideas why?

I typed in:

a.out < $(cat test1 test2)
