Make a copy of your shell start up file before editing it to change environment or shell variables. You can always return to using this copy if you find that the modified file is not working and you are unable to fix the problem. For example: cd cp .profile old_profile ue .profile . The first command changes you to your home directory, where a copy of the file .profile is made in old_profile . ... To revert to using the original .profile you simply copy it back. ...

... Recent development at UKIRT has shown that re-configurable data file writing isn't only quite possible but also advantageous in the short as well as in the longer run. ... All the considerations that drove data file writing in the beginning became less important, but something else became more important at the same time: maintainability and portability, as well as, at least in our case, the wishes of the scientists to change things around as instrument configurations change. ...

... The first step is to open and inspect the camera body. ... Notice that there are snap locks on both sides of the camera body, one of which should already be open since it contained the film removed by the developer.
