Linux Script, Concatenation doing Odd Behavior

Dear Experts,

I'm using an old version of cygwin, and
trying to get a simple script to work.

Input:
text file of package names, packages_all.txt

Output:
supposed to be a list of commands
created by
concatenating strings together

But I keep getting weird results.

The first two strings concatenate and
echo to screen fine.

But when I try to add a third string,
it does not get appended to the end.
But to the front.

Please take a look at the examples.

Any ideas on how to get this simple task work?

Thanks a lot

install.packages( "xopen

- As expected

while read LINE
do
prefix='install.packages( "'

newline=$prefix$LINE
echo $newline
done < packages_all.txt

...
install.packages( "yaml
install.packages( "zeallot

- As expected
- $suffix unused

----------

while read LINE
do
prefix='install.packages( "'
suffix=')'
newline=$prefix$LINE$suffix
echo $newline
done < packages_all.txt

...
)nstall.packages( "xtable
)nstall.packages( "yaml
)nstall.packages( "zeallot

- $suffix gets appended to the front
overwriting the first character
