This is my userland base I use at work, and on any other computer I use with a unix-like OS.

I've found that I've become entirely dependant on using it, so I can honestly say it's stood the test of time.  It keeps my .vim settings consistent as well as provides many simple perl script tools I wrote myself.

My magnum opus here though is the bin/vim.pl script, which has saved me from thousands of headaches.  I've described 10 "problems" and their solutions in the script itself, so have a look at it and read the comments to get an idea of what it can do you for you, if you use Vim.  I told a few others what this script can do, and their professional lives have improved significantly.

Other useful things I use on a daily basis in the bin directory:

abs         - STDIN / cmdline argument absolute path converter.  I use this all the time!
add         - quick way to do math via a tally based on newlines
after       - returns an exit code if it's after a certain hour.  ex. after 4pm && echo "beer time"
awky        - does arguably the most common use for awky, printing columns, without the hassle of
              writing in awk.  ex:  ls -l | awky 5 2 1
edit        - take in any STDIN, number each line, and allow you to edit a file found in it.  I use
              bash functions to fully use this, but you can get the idea if you do: ls -l | edit 5
fingerprint - quickly retrieve the fingerprint info from most systems, instead of having to google for
              its location etc
get         - hexidecimal / decimal converter and diagnostic tool.  I used this very often trying to
              reverse engineer an MSN encryption application
hl          - similar to grep, but highlights a query so you can see the entire context still
killme      - good for killing everything but your current shell.  useful when the #$!% hits the
              fan via a shell infinite loop.  (not perfect, but good enough)
lc / uc     - lowercase / uppercase STDIN or a file
lg          - line grabber, useful for grabbing lines from STDIN or a file via ranges, integers, etc
ls          - frontend for ls to be far more forgiving for typos and bad arguments due to keyboard
              layouts
man         - load man pages in vi!
math        - loads up 'bc', but much more forgiving on the syntax you use
md5         - makes md5summing of small strings easier
ms          - mass substitution.  takes in files via STDIN quickly make changes
perlregex   - simple test to find which characters match a small regex string
psx         - easier way to grep the process list
strlen      - find out the string length of a string much easier.  STDIN or by argument!
table       - my own syntax for creating SQL tables
tar         - tired of writing tar syntax?  tired of it not detecting if it's a .bzip2 or .gz archive?
              this frontend makes tar behave like rar/arj now
today       - find out what's been edited today.  I used this a lot before I learned git
trim        - simple STDIN whitespace trimmer
uniq.pl     - perl based uniq script, does not need input sorted.  yay
which_*     - this will allow you to make 'which' search aliases too, and colour code the results to
              tell the difference.  See the first script to get setup
wipe        - reset a filesize to 0
