Here's what my process looks like:
1 - I receive a PGP encrypted file to server A.
2 - I make a call to a key store on another server (server B) to pick up the private key needed to perform the decryption on server A.
3 - I decrypt the file, and run an encryption routine on the account number portion of the decrypted file. I may encrypt the entire file, though not sure yet.
4 - I send the protected file off to its destination server (server C).
5 - I now need to permanently delete (ensure the data cannot be recovered from the disk utilizing any software or hardware scanning device) the private key picked up from step 2 in addition to the decrypted file from step 3.
I hope you can see where my pain is, and I'm not sure if you're tail command would sufficiently protect the information. Can you confirm?

xtsetsensitive
XtSetSensitive(3Xt) XT FUNCTIONS XtSetSensitive(3Xt)
NAME
XtSetSensitive, XtIsSensitive - set and check a widget's sensitivity state
SYNTAX
void XtSetSensitive(w, sensitive)
Widget w;
Boolean sensitive;
Boolean XtIsSensitive(w)
Widget w;
ARGUMENTS
sensitive Specifies a Boolean value that indicates whether the widget should receive keyboard and pointer events.
w Specifies the widget.
DESCRIPTION
The XtSetSensitive function first calls XtSetValues on the current widget with an argument list specifying that the sensitive field should
change to the new value. It then recursively propagates the new value down the managed children tree by calling XtSetValues on each child
to set the ancestor_sensitive to the new value if the new values for sensitive and the child's ancestor_sensitive are not the same.
XtSetSensitive calls XtSetValues to change sensitive and ancestor_sensitive. Therefore, when one of these changes, the widget's set_values
procedure should take whatever display actions are needed (for example, greying out or stippling the widget).
XtSetSensitive maintains the invariant that if parent has either sensitive or ancestor_sensitive False, then all children have ances-
tor_sensitive False.
The XtIsSensitive function returns True or False to indicate whether or not user input events are being dispatched. If both core.sensitive
and core.ancestor_sensitive are True, XtIsSensitive returns True; otherwise, it returns False.
