whenever i try to execute a ruby file thro cron, i have to write a
crapper to cd the folder of the ruby file and then execute it. it is
such a hassle. what are the alternatives so that i dont have to write
a wrapper. the prob that i get if i run them directly is that it tries
to run in the same directory of the cron and cannot find the local
libraries that my require statments have. how can i get ruby to
execute the rb file in a specific directory. or is there any other
option.

Usage: ruby [switches] [--] [programfile] [arguments]
-0[octal] specify record separator (\0, if no argument)
-a autosplit mode with -n or -p (splits $_ into $F)
-c check syntax only
-Cdirectory cd to directory, before executing your script
-d set debugging flags (set $DEBUG to true)
-e 'command' one line of script. Several -e's allowed. Omit [programfile]

-l enable line ending processing
-n assume 'while gets(); ... end' loop around your script
-p assume loop like -n but print line also like sed
-rlibrary require the library, before executing your script
-s enable some switch parsing for switches after script name
-S look for the script using PATH environment variable
-T[level] turn on tainting checks
-v print version number, then turn on verbose mode
-w turn warnings on for your script
-W[level] set warning level; 0=silence, 1=medium, 2=verbose (default)
-x[directory] strip off text before #!ruby line and perhaps cd to directory
--copyright print the copyright
--version print the version

I guess the -I (that is "i".upcase) is the option you need, AAMOF cron
jobs are not exactly executed as in a login shell, I ignore(1) the
details, but man cron will explain this in detail.
Just for curiosity, which cron are you using and in which context (cygwin?).

I am using python cron on windows and -I is just what the doc
prescribed. its works beautifully.
