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.

What is the difference between the cat and more commands in Unix?
Both the 'more' and the 'cat' commands will list the contents of one or more files. In that case, the main difference between the two commands is that 'more' is a 'pager' program, meaning that it stops at the end of every page and waits for the user. The 'cat' command will list everything in the file without stopping. One other thing that 'cat' does that 'more' does not is to concatenate (add/merge) files together. 'more' is not designed to do that. Lastly, some versions of 'more' can traverse a file forwards and backwards and have simple searching capabilities, which 'cat' does not.
