How I can add the same text to several files via script?

Question

I want a simple way to add the same text (e.g. "bye" or more lines) to a group of files using a small script. I tried something with ed and vi inside of a script, but it did'nt work.

Edit: I edit this coment to be more specific:

I have the files c0001.gin c0002.gin ... up to let's say 500. I need to add to the end of each file the next text:

species
Ca    core  2.00000000
Co    core  2.00000000
C     core  1.34353898

I want just a script to do that.

Furthermore, the files are in folder called "CALCS" and I wanted to move each file to another folder inside CALCS called "001" for c0001.gin, "002" for file c0002.gin and so on.

Thanks in advance

Something like `for file in ; do echo "" >> "${file}" ; done`. — Biffen, Oct 09 '15 at 07:46
@Biffen -bash: syntax error near unexpected token `<'. Sorry for my english, not everyone speak english fluently. — git, Oct 09 '15 at 07:57
`` and `` are meant to be replaced. Since you've not told us to *which* files you want to write you'll have to do that bit yourself. — Biffen, Oct 09 '15 at 07:59
So, as @Biffen says, if you want to add the words "grey tails" to all files whose names begin with "elephant"... `for f in elephant*; do echo "grey tails" >> "$f" ; done` — Mark Setchell, Oct 09 '15 at 08:06

git - this whole swarm of confusion is caused by the failure to provide a concise example of your code which we here can verify and make suggestions from. We all suffer from the same limitations -- we cannot see what is on your screen... That's where you have to help us — David C. Rankin, Oct 09 '15 at 08:14
@DavidC.Rankin Desk. And not that softly. Glad someone understands. — Biffen, Oct 09 '15 at 08:16

#!/bin/sh

text="${1:?Usage: $0 <text> <file>...}"
shift
files="${@}"

for file in $files
do
    echo "$text" >> "$file"
done
