Yes, but if you someone already has shell access to *that* account, then there is already a bigger problem. If I create a script like the above, and make it chmod 755, nobody is going to get the sensitive data unless they are logged in as me, althought anyone can read (and run) the script themselves. You can even use very restricted accounts (e.g. no shell access) for more security. The point is, you completely separate the sensitive data from the script. I like this particular way because I can do something like this in .bashrc:

alias oradev='export ORACLE_SID=dev; export ORACLE_PASS=foo; \ export ORACLE_PASS=bar; echo Set instance to development'

...which allows easy interchange of instances, passwords, and other parameters from the command line. Nothing wrong with setting good permissions on an included file, either, but if you can run/read the script, you can track down and read the passwords.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
