as a result 187.25 that's why it is rounded up to 187..

try this...

Code:
awk -v VAR="$TOTAL_RECORDS" 'BEGIN {s=(VAR * 25 /100);split(s,a,".");if(a[2] > 49 ){printf "%.F",s}else{printf "%.F",(s+0.50} }'

And also I would like to write these 75 % and 25 % records to two new files for that I did something like this
Code:
File75=`head -n $REC_75 $File > temp1.txt`

File25=`tail -n $REC_25 $File >temp2.txt`

its not writing anything into the files

Please let me know whether I am doing anything wrong. I appreciate it.

Thanks

Thanks again Pamu

but the code you gave for ReC_25 is not working i am getting this error

Code:
"unexpected newline or end of string"

awk: cmd. line:1: BEGIN {s=(VAR * 25 /100);split(s,a,".");if(a[2] > 49 ){printf "%.F",s}else{printf "%.F",(s+0.50) }
awk: cmd. line:1:                                                                                                   ^ unexpected newline or end of string

Code:
#!bin/sh
#Param
INPUT_FILE='abc.txt'

TOTAL_RECORDS=$(wc -l < $INPUT_FILE)

echo $TOTAL_RECORDS

REC_75=`awk -v VAR="$TOTAL_RECORDS" 'BEGIN {printf "%.0f",(VAR * 75 /100) }'`

echo "$REC_75"

REC_25=`awk -v VAR="$TOTAL_RECORDS" 'BEGIN {s=(VAR * 25 /100);split(s,a,".");if(a[2] > 49 ){printf "%.F",s}else{printf "%.F",(s+0.50)}'`

echo "$REC_25"

I am writing these two REC_75 and REC_25 into two different files REC_75 is working fine and REC_25 is not working I got the error which I mentioned in the earlier email.
