There is also a problem with the remote command.
It is evaluated once on the calling system and another time on the remote system.
To solve, put the remote command in 'ticks'. And solve the problem with the embedded ticks.
Code:
ssh -o ConnectTimeout=15 -n -l USER SERVER 'awk -F\; '"'"'{ if ( $3 == "-" && $1 ~ /[ES]/ ) print }'"'"' *20130706*'

That looks ugly.
Better save the normal command in a file "remotecommand.sh"
Code:
#!/bin/sh
awk -F\; '{ if ( $3 == "-" && $1 ~ /[ES]/ ) print }' *20130706*

And send that to the remote server (without -n)
Code:
ssh -o ConnectTimeout=15 -l USER SERVER /bin/sh < remotecommand.sh

The script interpreter (/bin/sh) is called explicitly, and the normal command is piped through the ssh to it.
NB: I replaced the '\;' delimiter by a simple \; meaning a semicolon.

rake

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME

     rake -- Ruby Make

SYNOPSIS

     rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE]
	  [-r MODULE] [--rules] [variable=value] target ...

DESCRIPTION

     Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command.

     Rake has the following features:

     o	 Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax.  No XML files to edit. No quirky Makefile syntax
	 to worry about (is that a tab or a space?).

     o	 Users can specify tasks with prerequisites.

     o	 Rake supports rule patterns to synthesize implicit tasks.

     o	 Flexible FileLists that act like arrays but know about manipulating file names and paths.

     o	 A library of prepackaged tasks to make building rakefiles easier.

OPTIONS

     --version		 Display the program version.

     -C
     --classic-namespace
			 Put Task and FileTask in the top level namespace

     -D [PATTERN]
     --describe [PATTERN]
			 Describe the tasks (matching optional PATTERN), then exit.

     -E CODE
     --execute-continue CODE
			 Execute some Ruby code, then continue with normal task processing.

     -G
     --no-system
     --nosystem 	 Use standard project Rakefile search paths, ignore system wide rakefiles.

     -I LIBDIR
     --libdir LIBDIR	 Include LIBDIR in the search path for required modules.

     -N
     --no-search
     --nosearch 	 Do not search parent directories for the Rakefile.

     -P
     --prereqs		 Display the tasks and dependencies, then exit.

     -R RAKELIBDIR
     --rakelib RAKELIBDIR
     --rakelibdir RAKELIBDIR
			 Auto-import any .rake files in RAKELIBDIR.  (default is rakelib )

     -T [PATTERN]
     --tasks [PATTERN]	 Display the tasks (matching optional PATTERN) with descriptions, then exit.

     -e CODE
     --execute CODE	 Execute some Ruby code and exit.

     -f FILE
     --rakefile FILE	 Use FILE as the rakefile.

     -h
     --help		 Prints a summary of options.

     -g
     --system		 Using system wide (global) rakefiles (usually ~/.rake/*.rake ).

     -n
     --dry-run		 Do a dry run without executing actions.

     -p CODE
     --execute-print CODE
			 Execute some Ruby code, print the result, then exit.

     -q
     --quiet		 Do not log messages to standard output.

     -r MODULE
     --require MODULE	 Require MODULE before executing rakefile.

     -s
     --silent		 Like --quiet, but also suppresses the 'in directory' announcement.

     -t
     --trace		 Turn on invoke/execute tracing, enable full backtrace.

     -v
     --verbose		 Log message to standard output (default).

     --rules		 Trace the rules resolution.
