Flat file-make field length equal to header length

Hello Everyone,

I am stuck with one issue while working on abstract flat file which i have to use as input and load data to table.

Input Data-

------ ------------------------ ---- -----------------
WFI001 Xxxxxx Control Work Item A Number of Records

------ ------------------------ ---- -------------------------
WFI001 Xxxxxx Control Work Item B Count of Distinct Hook Id

------ ------------------------ ---- -------------------
WFI001 Xxxxxx Control Work Item C Sum of Workitem Num

------ ---------------------- ---- -----------------
WFI008 Xxxxxx Control DocTABA A Number of Records

You can consider ----- as header for a field.
I cant starighforward load this file because if you check column values -they have spaces in them ;so i need to enclose indivisual column in double quotes.

Output i expect is
"WFI001" "Xxxxxx Control Work Item" "A" "Number of Records"
"WFI001" "Xxxxxx Control Work Item" "B" "Count of Distinct Hook Id "
"WFI001" "Xxxxxx Control Work Item" "C" "Sum of Workitem Num "
"WFI008" "Xxxxxx Control DocTABA" "A" "Number of Records "

Any help or suggestions in this query will be of great help.

Thanks!!!

Code:
# sed '/^-\|^$/d' data
WFI001 Xxxxxx Control Work Item A Number of Records
WFI001 Xxxxxx Control Work Item B Count of Distinct Hook Id
WFI001 Xxxxxx Control Work Item C Sum of Workitem Num
WFI008 Xxxxxx Control DocTABA A Number of Records

@ygemici,any idea how to put double quotes around column 2 and column 4
# 5  
awk

Hi,

Check out this,

Code:
awk '/^-/{split($0,a," ");}$0 !~ /^-/{for(i=1;i<=length(a);i++){t=substr($0,0,length(a[i]));if ( t ~ / / && length(t) == 4 ){split(t,b," ");t=b[1];}gsub(t,"");sub(/^ /,"");r="\""t"\"";temp=temp" "r;}sub(/^ /,"",temp);print temp;}' file

Cheers,
RangaSmilie

try this Smilie
Code:
# sed '/^-\|^$/d;$!s/\([^ ]*\) \([^ ]* [^ ]* [^ ]* [^ ]*\) \([^ ]*\) \(.*\)/"\1" "\2" "\3" "\4"/
;$s/\([^ ]*\) \([^ ]* [^ ]* [^ ]*\) \([^ ]*\) \(.*\)/"\1" "\2" "\3" "\4"/' data
"WFI001" "Xxxxxx Control Work Item" "A" "Number of Records"
"WFI001" "Xxxxxx Control Work Item" "B" "Count of Distinct Hook Id"
"WFI001" "Xxxxxx Control Work Item" "C" "Sum of Workitem Num"
"WFI008" "Xxxxxx Control DocTABA" "A" "Number of Records"
