Top Forums Shell Programming and Scripting KSH problem - how do i redirect three times? Post 302241788 by mjays on Tuesday 30th of September 2008 08:58:57 AM

sorry but i was a little premature.

things still aren't right.

the problem is, i need the script to exit if the ls command fails, but all it does is display the error and then write to the log file.

this is the ls command and the code after it

Code:
ls -lR ${BUILD_CODE} 2>&1 >${REL_FILES}/${RELNO}.txt | tee -a ${LOGFILE}
if [ $? -ne 0 ]
   then
       exit
fi

so you see, the tee command is probably successful which gives me a $status of 0.

how do i interogate the error from the ls command when it's tucked in way back there?
