Hello lakshmanraok,

I think following command will make more sense.(Which I assume may fulfil your requirement of removing spaces
from a variable and take it's output to a file, with showing errors to standard output)
Code:
echo "$abcd" | sed 's/ //g' >> ${LOGFILE} 2>&1

Following explaination may help you in same.
echovalue of variabe named abcd with echo "$abcd" then remove the spaces in it with NULL with sed 's/ //g'
and taking output to redirect standard error to standard output >> ${LOGFILE} 2>&1


Thanks,
R. Singh
