quickest (i blv) way to get the current program name minus the path (BASH)
Useful in shell scripts when you're trying to get the shell script name without the full path - and easier than awking or cutting. Bash pattern matching and variable manip is fun.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Using parcellite, indents the content of the clipboard manager
This command takes the content of a Parcellite-managed clipboard manager and add one level of indentation to it. It may be useful to indent a block of code which will enter inside another, already indented one but I use it mostly to indent code I will post in Stack Overflow questions and answers.

Short Information about loaded kernel modules
Run this as root, it will be helpful to quickly get information about the loaded kernel modules.

Compress excutable files in place.
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them. FYI: You can compress any executable sha-bang scripts as well (py, pl, sh, tcl, etc.).

One command line web server on port 80 using nc (netcat)
Very simple web server listening on port 80 will serve index.html file or whatever file you like pointing your browser at http://your-IP-address/index.html for example. If your web server is down for maintenance and you'd like to inform your visitors about it, quickly and easily, you just have to put into the index.html file the right HTML code and you are done! Of course you need to be root to run the command using port 80.
