I have this condition in order to send me a log if it encounters any of this word.  The thing is I need this "case sensitive', because the log has a filename with the word "Rejected" in it and send me the log as it where an error.

PARAM1=$(egrep -i -c "ORA-|rejected|Killed|skipped|EXP-" "$log")

i think you need to remove option -i from command

PARAM1=$(egrep -c "ORA-|rejected|Killed|skipped|EXP-" "$log")

Yes,

the "-i" flag means "Ignore the case (uppercase or lowercase) of letters when making comparisons", so it should obviously not be used here.

But moreover, egrep supports some kind of regular expressions, so assuming you were searching for "Killed" or "killed" or "rejected" but not "Rejected" you could do:

egrep -c "ORA-|rejected|[kK]illed|skipped|EXP-" "$log"

or assuming you were searching for "ORA-" messages whose numbers start with 1, 2, 3 or 9 you could do:

egrep -c "ORA-[1-3,9]|rejected|[kK]illed|skipped|EXP-" "$log"

A last example: Search for "dropped" or "skipped":

egrep -c "ORA-[1-3,9]|rejected|[kK]illed|(dro|ski)pped|EXP-" "$log"

Have fun!
