I have the following script as shown below where I cat a file and then also tee the output to a file as I have to email the execution of the process to users at the end of the script:
Code:
cat incoming.dat | tee -a execution.log
if [ $? != 0 ]
then
echo "Issue with incoming.dat file, file not present"
exit 1
else
echo "data from incoming.dat file as follows:"
fi
echo -e "Execution Log" | mail -s "Log File" -a execution.log info@abc.com
The problem with above command is when there is no incoming.dat file present, the script isnt failing. When incoming.dat file isnt present, the cat command fails but since it able to successfully direct the output to tee, it never goes to "exit 1" part of the if statement. I cant remove the tee part as I need to print the command output in the stdout as well as direct it to a file as I have to email it to users. How can I fix this issue?
Thanks for any inputs,
Carl

GETRUSAGE(3) 1 GETRUSAGE(3)getrusage - Gets the current resource usagesSYNOPSIS
array getrusage ([int $who])
DESCRIPTION
This is an interface to getrusage(2). It gets data returned from the system call.
PARAMETERS
o $who
- If $who is 1, getrusage will be called with RUSAGE_CHILDREN.
RETURN VALUES
Returns an associative array containing the data returned from the system call. All entries are accessible by using their documented field
names.
EXAMPLES
Example #1
getrusage(3) example
<?php
$dat = getrusage();
echo $dat["ru_nswap"]; // number of swaps
echo $dat["ru_majflt"]; // number of page faults
echo $dat["ru_utime.tv_sec"]; // user time used (seconds)
echo $dat["ru_utime.tv_usec"]; // user time used (microseconds)
?>

NOTES
Note
On Windows getrusage(3) will only return the following members:
o "ru_stime.tv_sec"
o "ru_stime.tv_usec"
o "ru_utime.tv_sec"
o "ru_utime.tv_usec"
o "ru_majflt" (only if $who is RUSAGE_SELF)
o "ru_maxrss" (only if $who is RUSAGE_SELF)
If getrusage(3) is called with $who set to 1 ( RUSAGE_CHILDREN), then resource usage for threads are collected (meaning that inter-
nally the function is called with RUSAGE_THREAD).
Note
on BeOS 2000, only the following members are returned:
o "ru_stime.tv_sec"
o "ru_stime.tv_usec"
o "ru_utime.tv_sec"
o "ru_utime.tv_usec"
