How to call a C program in a shell... [message #196129] Wed, 04 October 2006 04:38 Go to next message

Hi All,
Good Morning.

In one of our development server, there is a shell program, which in turn calls a 'c' program.

The c program is compiled and is in executable form.

But it is found that it's not all using the C program
and it skips that program (or unrecognised it?)


here the coding is:

#!/bin/ksh

log_file=/prod/bin/AAA.log
history_file=/prod/history/history.txt
date_stamp=`date "+ %d%m%Y"`

echo "Processing Begin: $date_stamp" >> $log_file
if [ -s "/prod/tmp/AAAA.data" ]
then
echo "Input file found"
if [ ! -s "$history_file" ]
then
echo "STATUS" > $history_file
echo "PROCESSING DATE" >> $history_file
fi

# the follwing "processnew1" is the C program
processnew1
echo "Successfully Completed" >> $log_file
else
echo "Processing: No Input file is there." >> $log_file
fi
echo "Processing End: $date_stamp" >> $log_file
~

The output logfile contains
" Processing Begin: 04102006
Processing: No Input file is there.
Processing End: 04102006 "

===============

File permission

The source program
-rw-r--r-- 1 lms lmsgrp 1826 Oct 4 15:52 processnew1.cc

After compilation with execute permission
-rwxr-xr-x 1 lms lmsgrp 8688 Oct 4 15:56 processnew1

---

Could you please guide me...

Thanks a lot.

Regards,
Raja

Immediately after the program - echo the return code. You need to know what the return codes mean - check with the programmer.

processnew1 
echo "return code is $?"
