Shell Programming and Scripting

Have a script that scp's tar file to multiple other servers in a for loop. Need to set monitoring and notification on it for when it fails.

Running this line of code in a 'for' loop...

scp $SOURCE_RECOVERY_TARFILE ${HOST}:${CURR_RECOV_TARFILE} 2>&1 | tee ${MONFILE}

Their are two outputs from a forced error... a redirect from the executable to a log file for the entire script. Then I'm also trying to monitor each loop for errors so we know where and when the script is failing.

Currently the script log looks like this...

^M^[[3g^M ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H
^[H ^[H ^[H ^[H ^[H^MCOS dbtool1
logout

My loop error file ( $MONFILE ) is showing up empty while the screen is showing...

./recovery_COS_ASEs.dev[38]: SOURCE__RECOVERY_TARFILE: Parameter not set.
logout

All the methods I've tried for redirecting output to a file isn't working on this HPUX server. Any ideas, I'd be grateful.

./recovery_COS_ASEs.dev[38]: SOURCE__RECOVERY_TARFILE: Parameter not set.
Perhaps :
Script file is : ./recovery_COS_ASEs.dev
nounset option is selected (ksh, set -o nounset) and variable SOURCE__RECOVERY_TARFILE is not set or define.

You are correct, this is the error I forced. I'm trying to get that error message to write to a file... for some reason its not reading standard out.

The error message is displayed on stderr by the shell, not by the scp command.
If you want to catch the message you must redirect the stderr of you shell.
First solution:

Code:

./recovery_COS_ASEs.dev 2> errorfile

Second solution, inside the script

Code:

exec 2> errorfile

Jean-Pierre.

its odd,

when the following is run..

scp $SOURCE_RECOVERY_TARFILE ${HOST}:${CURR__RECOV_TARFILE} 2> ${MONFILE}

the monitor file ($MONFILE) is not created... when I run the one below the $MONFILE is created but its empty with the error message "Parameter not set" just showing up on the screen and not getting read to the ${MONFILE}.

scp $SOURCE_RECOVERY_TARFILE ${HOST}:${CURR_RECOV_TARFILE} 2>&1 ${MONFILE}

Why not simply request the return code of the scp command?
It will indicate if the copy succeeded.


for HOST in .........
do


scp .........................
if [ $? -ne 0 ]
then
echo "copy failed to host: $HOST
fi

done

Thanks I really do appreciate it,

I'll give it a shot and let you know... I've gotta work on something else for the rest of the day.
