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] -Eencoding specifies the character encoding for the program codes -Fpattern split() pattern for autosplit (-a) -i[extension] edit ARGV files in place (make backup if extension supplied) -Idirectory specify $LOAD_PATH directory (may be used more than once) -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 -- remember.guy do |as, often| as.you_can - without end http://blog.rubybestpractices.com/ |
