An example might be helpful. P.S. The 'out-of-the-box' awk's can only define RS as single characters - no regex for RS.

my in put file is:
<CRM:MS=23746,............................; <EN:MS=23746..........................; ................................................; <CRM:5766,..............; <OP:.................................; my input file looks like this. in place of dots there are some more parameters. what i want is that the record separator new line (currently ) is replaced. i want the script to accept <CRM: as new field separatori.e my output file should look like: <CRM:MS=23746,............................;<EN:MS=23746..........................;.................. ..............................; <CRM:5766,..............;<OP:.................................; it will be very nice of you if you can help.

use 'gawk' if you can:
Code:
# # set the RecordSeparator to '<CRM:' # # for the FIRST line - reevaluate the record equal to itself # for any OTHER line - reevaluate the record appending the RecordSeparator # to the beginning of the record. # # after the reevaluattion is done - PRINT the record. 'PRINT' is implicit as a # result of the record re-evaluation. # gawk -v RS='<CRM:' '$1=(FNR==1) ? $1 : RS $1' myFile Code:
# for the FIRST line/record - print it out (withOUT a new line) and o to the next line
FNR==1 { printf ;next }
#
# for any OTHER (other than the first) line/record:
# if the line/record starts with '<CRM:' - print the new line '\n' followed by
# a line itself.
# if the line/record does NOT start with '<CRM:' - print the line withOUT
# a new line '\n'
{printf (/^<CRM:/) ? "\n" $0 : $0}
# print new line '\n' after the LAST line processed
END { printf "\n" }
