sudox (sudo for X) is  a bash script that executes commands under X in UNIX and LINUX as an arbitrary user with sudo. It provides  the necessary privileges using xauth over a pipe. I use it for example to execute firefox as  a different user with low privileges. Maybe you use sux allready. So what sux is to su, sudox is to sudo.

secbak and secrest are scripts for use with afio a cpio replacement. The scripts implement incremental multi-volume backups and restore. Unlike with tar, files are compressed individually and can be optionally encrypted.

publish_only_PUBLIC_subtrees.sh is a bash script that reconstructs parts of a UNIX or LINUX directory tree with symbolic links. I use it in order to publish automatically selected parts of my hard disk on a web server. Only files and directories within folders named PUBLIC are published.

lnr -s is a bash script which creates symbolic links with the same syntax then the UNIX command ln -s. Unlike ln -s it searches the shortest relative path between the source and destination and creates the link with a relative path. Most of the time symbolic links are very short in distance and used mainly to reduce redundancy. The advantage of relative symbolic links is that the whole directory can be moved without breaking the links. If you do so, please make sure that directory you want to move does not does not contain relative links pointing ourside of the moving directory.

My enhanced version of Paul Wilkins RPN calculator:. grpn is a graphical reverse polish notation (RPN) calculator which handles real numbers, complex numbers, matrices, and complex matrices. This version of grpn adds engineering notation, the remainder function (mod) and can decompose complex numbers. Results can be copied to the clipboard and used elsewhere. See screen-shot and changelog for details. Here you can find a patch against the last version grpn-1.1.2.tar.gz from the author Paul Wilkins.
