How to split a data assigned to a variable
The requirement is, there is a log file which contains a huge data. i need to get a particular field out of it by searching with another field.

ex:

2011-03-28 13:00:07,423 [http-8080-9] : millis=231 q={ call get_data_account(?,?,?,?,?) }, params=[1:xxxxxx,2:bbbbbbb3:ccccccc,4:dddddd,5:null]

i need to search for the word "get_data_account" in file and from that i need to get the field "xxxxxx" and store it in a variable.

this "get_data_account" will be present more than one time and and there will be different "XXXX" values.


i used it in a for loop for all the files and below is the code.

Code:
IFS='\n'
for Search in "$(less "$logfile" | grep get_data_account)"
do
 accountId=`echo "$Search" | awk -F ':' '{print $8}' | cut -d ',' -f1`
 
 echo $accountId 

done

but when i echo the accountId i get the below
accountId='1234
5678
9012
2344'

but when i use it another for loop to display it it is taken as a single string not as a single accountId's and display it in a single line same as the above output.

i have tried both with and with out IFS both are giving the same output.

DESCRIPTION

       set_field_type()  associates  the specified field type with field. Certain field types take additional arguments. TYPE_ALNUM, for instance,

       TYPE_NUMERIC, and TYPE_REGEXP.

       field_type() returns a pointer to the field type of field. NULL is returned if no field type is assigned.

       field_arg()  returns  a	pointer  to  the  field  arguments  associated	with the field type of field. NULL is returned if no field type is
       assigned.

RETURN VALUES

       field_type() and field_arg() return NULL on error.

       set_field_type() returns one of the following:

       E_OK		 The function returned successfully.
