Quick access to the ascii table.

Find all files under a certain directory /home that have a certain suffix at the end of the file name. Show the file and rename them to remove the suffix.

Run a program transparently, but print a stack trace if it fails
For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files. The one downside is that it does smoosh your program's stderr and stdout together.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Changing the terminal title to the last shell command
Found the same command for zsh in http://www.davidpashley.com/articles/xterm-titles-with-bash.html - changed it a bit so that the behaviour is the same

Create backup copy of file, adding suffix of the date of the file modification (NOT today's date)
If your `date` command has `-r` option, you don't need `stat`

Monitor a file's size
use "watch" instead of while-loops in these simple cases

intercept stdout/stderr of another process

Cryptographically secure 32-bit RNG in strict ZSH
ZSH ships a couple random number generators via the $RANDOM environment variable and rand48() via zsh/mathfunc, but neither are cryptographically secure. This code produces a 32-bit random number suitable for cryptography. It's only dependency is /dev/urandom and it does not rely on any shell commands or 3rd party utilities. It assumes ZSH was compiled with 64-bit integer support.

Pretty Print a simple csv in the command line
Will handle pretty much all types of CSV Files. The ^M character is typed on the command line using Ctrl-V Ctrl-M and can be replaced with any character that does not appear inside the CSV. Tips for simpler CSV files: * If newlines are not placed within a csv cell then you can replace `map(repr, r)` with r
