Append data without using cat command

i was wondering weather is it possible to append data in a file without using cat command. I've considered using sed to append data , but as of my knowledge sed only operates after loading the full data into the memory. please do correct me if i'm wrong on this.

Instead of cat, you can also use echo command to do the same.

And ofcourse, >> operator does it.

If you want to append data to a file, you can simply use the append I/O-redirection >>. For instance:

echo "first line" > file
echo "next line" >> file

Or you could append an entire file

echo "$(<otherfile)" >> file

This command is however not advisable since it will load the entire file first into memory.

A better way is to use tee:

tee < otherfile >> file
