The 'merge' command is not standard in Unix, so not every system has it. The 'cat' command is standard in every Unix system. The 'cat' command merely echoes the contents of a file. It can be used to put together several files (concatenate). The 'merge' command (at least on Linux) merges changes from an original file to a modified (patched) file. It is considered a 3-way merge utility. Check the 'man' command for both and you will see the differences in the two commands.

You can easily see it as it looks like the normal file.
Use the "dir" command (without the quotes) to see all files in the current directory. Use the "type" command (Just like before, no quotation marks.) followed by a file you want to look at to see the file's contents. Use the "echo" command (Okay, I think you get the point about the quotation marks now.) to print something to the screen. Not very useful. Is it? You can use the "echo" command to overwrite files too! For example, "echo Hello >> a.txt" will overwrite a.txt with the text "Hello." If a.txt does not exist, the echo command will create one.
/var/log/dmesg is the file which contains kernel initializaion messages. By typing dmesg command in the shell prompt we can see

The ls command.
The 'wall' command is used to send a message to all users on the system. You can put the text of what you want each user to see in a file, or you can type the message in line by line and then send it. To send the contents of a file to each user, use the command: wall filename to send a message and type the contents at the same time, type: wall first line of text second line of text ... ^D to send it.
