I'm new to unix and the command line and am trying to learn different commands. I have a file (teledir.txt) that contains a name and phone number for 3 different people. I am writing a script that is to take two positional parameters and I typed out how it should behave:
I declared two variables: name=$1 and number=$2. But I'm lost on what command to use in the script to see if the name and/or number exists in the other file.

db2_num_rows
DB2_NUM_ROWS(3) 1 DB2_NUM_ROWS(3)db2_num_rows - Returns the number of rows affected by an SQL statementSYNOPSIS
int db2_num_rows (resource $stmt)
DESCRIPTION
Returns the number of rows deleted, inserted, or updated by an SQL statement.
To determine the number of rows that will be returned by a SELECT statement, issue SELECT COUNT(*) with the same predicates as your
intended SELECT statement and retrieve the value.
If your application logic checks the number of rows returned by a SELECT statement and branches if the number of rows is 0, consider modi-
fying your application to attempt to return the first row with one of db2_fetch_assoc(3), db2_fetch_both(3), db2_fetch_array(3), or
db2_fetch_row(3), and branch if the fetch function returns FALSE.
Note
If you issue a SELECT statement using a scrollable cursor, db2_num_rows(3) returns the number of rows returned by the SELECT state-
ment. However, the overhead associated with scrollable cursors significantly degrades the performance of your application, so if
this is the only reason you are considering using scrollable cursors, you should use a forward-only cursor and either call SELECT
COUNT(*) or rely on the boolean return value of the fetch functions to achieve the equivalent functionality with much better perfor-
mance.
PARAMETERS
o $stmt
- A valid stmt resource containing a result set.
RETURN VALUES
Returns the number of rows affected by the last SQL statement issued by the specified statement handle.
