You can try as,

sed -e "/[eE][rR][rR][oO][rR]/p;/[eE][xX][cC][eE][pP][tT][iI][oO][nN]/p" $LOG_DIR/Node$i\Log.txt >> $LOG_ERR_REP

It will work.

Firstly, what is wrong with your grep? I suspect you are using GNU grep and want extended regexes - in which case you need upper case -E

grep -i -E "error|exception" file >> another_file

Or, if you're not using GNU grep

egrep -i "error|exception" file >> another_file

Also; why are you backslash escaping the L of Log.txt?

Cheers
