paste.sheet

  Puts lines from two files together, either lines of each file side by side (normally separated by a tab-stop but you can have any symbols(s) you like...) or it can have words from each file (the first file then the second file) side by side.
  
  To obtain a list of lines side by side, the first lines from the first file on the left side separated by a tab-stop then the first lines from the second file. You would type:
  $  paste file1.txt file2.txt
  
  To have the list displayed in serial, first line from first file, [Tab], second line from first file, then third and fourth until the end of the first file type:
  $  paste --serial file1.txt file2.txt
