[Solved] awk FS

I have a script which uses awk to read from a file seperated with commas, although saved as a .conf file.

Code:
 awk -F, '{print $3}'

it is meant to pick up "a label here" (for example)

But instead return "a"

Problem is that although the command does recognise the comma seperation it still recognises blank sapces also as deilimiters, which means the next command printing the $4 variable is picking up the blank space " ".

Is there any way to get awk to completely ignore blank spaces and just use the commas as delimiters? The field I am reading must remain as it is and I cannot remove the spaces.

---------- Post updated at 04:02 AM ---------- Previous update was at 03:55 AM ----------

sorry problem solved.

The issue was with the rest of the command, which was:
Code:
KEY_LBL=`printf ${FILE}| awk -F, '{print $3}'`

However I changed it to:
Code:
KEY_LBL=`echo ${FILE}| awk -F, '{print $3}'`

and it now works a treat. Simple echo / printf issue.

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.
