First: I have no clue about perl and java.
Second: I use C, but never used in conjunction with a database

I the datsbase should queried from, e.g., a procmailrc and check
for IP addresses and much more. Most TABLES has only 2 or 3 COLS

The problem are the ROWS of the database.

So I am searching for a simpel solution to access the DB from BASH

OK, I have already codes stuff in php and the RETVAL was simpel
"VAL1 VAL2 VAL3" which I can cut into:

RETVAL=`php pg_query.php $SERVER $DB $TABLE $COL $SEARCH`
if [ $? == "1" ] ; then exit 1 ; fi
VAL1=`echo $RETVAL |cut -d " " -f1`
VAL2=`echo $RETVAL |cut -d " " -f2`
VAL3=`echo $RETVAL |cut -d " " -f3`

where the pg_query.php has serched only in the
given $COL and returnd the whole $ROW as RETVAL.

I was thinkg that such tool already exist in C.

But if you have a DB of 10.000 lines, the above examle will be faster
then a BASH solution with a file like

RETVAL=`grep "^$SEARCH" $DB_FILE`
if [ $? == "1" ] ; then exit 1 ; fi
VAL1=`echo $RETVAL |cut -d " " -f1`
VAL2=`echo $RETVAL |cut -d " " -f2`
VAL3=`echo $RETVAL |cut -d " " -f3`

and pgsql can be updated concurently, a $DB_FILE not.

Oh yes, from time to time a have realy need for a DB even in stupid
BASH scripts because it makle the life easier.

And the other think is, the first $COL is every time UNIQ.
