Hello, i must do that but i dont know how. So if you so kind help me :-)
"Create a new command for Minix, that will be called UNITE. UNITE command will make and show on screen,in a file the contests of two files, joining together. The syntax must be like this : unite filename1 filename2 filename3
Filename1 and filename2 will be the names of the two joining files, and filename3 the file that will be produced.
The command should work like this : File filename3 will contain data of the filename1+filename2 joining (with that order) and will show it on screen.
The file that you create must be in /usr/src/commands/simple catalog with the name UNITE.C. Also you must modify the corresponding makefile."
Sorry for my bad english
