pwgrep is a simple password manager that manages a database file using encryption of GnuPG. It uses encryption and version control on all of the passwords that are stored. The password database can be used on several hosts at once with automatic synchronization. Even several users can share the same password database. The versioning system will keep track of who was changing which entries and at which time. The versioning system to use can be configured (and is Subversion by default). Besides passwords, pwgrep can also be used for storing a collection of files like certificates. The file shredding command for secure deleting of temporary files can be configured. A local backup of all database changes is automatically made. It can be used without a GUI (such as through an SSH session).
qtop is a command-line tool for monitoring PBS systems, especially torque. It tries to fit as much information as possible in the space of one screen by joining together the output of pbsnodes -a, qstat, and qstat -q, so it runs fine in user space. The screen is divided in three sections, reporting SUMMARY, NODES, and ACCOUNTS. Each user gets mapped to a unique letter, according to number of jobs in qstat. Symbol 0 is always the user with most R+Q+other jobs, 1 is next in number of jobs, etc. qtop uses and suppresses color mode automatically, as needed, so its output can be piped to other programs. It is very configurable.
