what is the syntax to get the count of 2 or more strings..

Hi,
I want to grep a file for 2 or more strings and get a count back.

for one string I have this..
RETVAL=`egrep -c '(PLS)-' ${my_file}`

what is the syntax to get the count of 2 or more strings..

if my file has any of these strings return the count
file name = "my_file"
strings="PLS" and "ORA" and "ERR"

Thx, Bill

Do you mean the cumulative count?

RETVAL=$(egrep -c 'PLS|ORA|ERR' $my_file)
echo $RETVAL

If you have to check for the presence of the parentheses and the minus sign (as in your example):

RETVAL=$(egrep -c '\(ORA\)-|\(ERR\)-|\(PLS\)-' $my_file)
echo $RETVAL

To count multiple matches per line (GNU grep only):

RETVAL=$(egrep -o '\(ORA\)-|\(ERR\)-|\(PLS\)-' $my_file |wc -l)
echo $RETVAL
