The paste command is similar to the cat command, it merges lines together in a file. Let's create a new file with the following contents:
Let's combine all these lines into one line:
$ paste -s sample2.txt
The default delimiter for paste is TAB, so now there is one line with TABs separating each word.
Let's change this delimiter (-d) to something a little more readable:
$ paste -d ' ' -s sample2.txt
Now everything should be on one line delimited by spaces.
Try to paste multiple files together, what happens?
What flag do you use with paste to make everything go on one line?
