[Help-bash] Expand file contents, bash-style

[Federico Prades Illanes]

Hi help-bash,

Recently after upgrading from from SuSE10(bash 3.1.7) to RedHat6.4(bash
4.1.2), and I started to have minor problems with one bash script, only
when it runs under Jenkins :/

I have a text file(file.txt) with keywords I'd like to expand with bash to
actual files. When I run this under my regular user I got expected
behavior. When it runs under a Jenkins slave it gets quoted.

$ ls
> files.txt  foo  fool  script.sh
> $ cat files.txt
> foo*
> $ cat script.sh
> #!/bin/bash -x
> echo $(< files.txt)
> $ ./script.sh
> + echo foo fool
> foo fool
> $


However under Jenkins

+ echo 'foo*'
> foo*


My first question, Is using $(<) an appropriate way to perform this
expansion?

Second question, what can be affecting Jenkins slave invocation of the bash
to actually quote the expansion?

Thanks in advance, I hope I was clear and succinct enough.
