Shell Programming and Scripting

mW = 10dBm/10
mW = dBm(10/10)
mW = dBm

In other words, multiplying a number by 10 and then dividing the result by 10 results in the original number.

So, using an alternate formula...

Code:

$ cat calc2
#! /usr/bin/ksh
bc -l |&
print -p scale=6


while read dbm?"enter dBm -->  "; do
        print -p  "e(($dbm-30)*l(10)/10)"
        read -p watt
        echo "dBm = $dbm     watt = $watt"
done
echo
exit 0
$ ./calc2
enter dBm -->  29.216870
dBm = 29.216870     watt = .835001
enter dBm -->  30.008670
dBm = 30.008670     watt = 1.001997
enter dBm -->

nawk 'BEGIN { w = 0.1; print 10*log(w) + 30 }'

I have a function check_ok in my abc.sh. which return me 1 or 0 . I want to call this fuction through other shell script. this shell also send two parameter to calling function.
Can you please tell me how. I am very new in unix.



#!/bin/bash

date_equal()
{

sqlplus -silent rep/qpalwo@cbi <<END
set pagesize 0 feedback off verify off heading off echo off serverout on size 100000
DECLARE
date1 DATE:=NULL;
date2 DATE:=NULL;
BEGIN
DBMS_OUTPUT.enable(100000);
select hdsg.HLD_DI_SRC_GRP_DATE into date_1 from di_hold.HOLD_DI_SRC_GRP hdsg where hdsg.HLD_DI_SRC_GRP_NAME = $1;

select hdsg.HLD_DI_SRC_GRP_DATE into date_2 from di_hold.HOLD_DI_SRC_GRP hdsg where hdsg.HLD_DI_SRC_GRP_NAME = $2;

select trunc(sysdate) into current_date from dual;
IF current_date = date_1 and current_date = date_2
THEN
DBMS_OUTPUT.put_line('1');
ELSE
DBMS_OUTPUT.put_line('0');
END IF;
END;
/
exit;
END

First thing is please open a new thread for your new request.

You can invoke the "abc.sh" from your other shell script like:
abc.sh arg1 arg2

In you abc.sh, make your function use these arguments as $1,$2 ... and return 1 or 0.
