/usr/bin/paste

Usage: /usr/bin/paste [OPTION]... [FILE]...
Write lines consisting of the sequentially corresponding lines from
each FILE, separated by TABs, to standard output.
The newline of every line except the line from the last file
is replaced with a TAB.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
  -d, --delimiters=LIST
         reuse characters from LIST instead of TABs;
         backslash escapes are supported
  -s, --serial
         paste one file at a time instead of in parallel; the newline of
         every line except the last line in each file is replaced with a TAB
  -z, --zero-terminated
         line delimiter is NUL, not newline
