/* ---------- "Column shifting" ---------- */
I'm wondering if there's been a program written that takes a file and
outputs that same file except with arbitrary columns shifted over.
Some examples are:

input file is: 0123456789

Move column 7 to column 1: 0712345689

Move column 7 to column 1, column 3 to column 5: 0712453689

Move column 7 to column 1, column 3 to column 8: 0712456839

This sounds a bit like the bubble sort, so I think it probably exists.
Just out of curiosity, are there any other algorithms out there?
Thanks.

Somebody just suggested using the "cut" command of SysV as the
solution to this.  I read the documentation and it looks like it
merely deletes certain columns or fields, but does not move them as I
wished.  Am I wrong about "cut"?  Any other ideas?
