Problem with If statement
Hi All,
I am writing an if statement to check multiple conditions, but when I try to execute the script it is breaking at the point of if statement by showing the issue below.
Quote:
line 23: [: missing `]'
line 23: -f: command not found
Code I am using is given below.
HTML Code:
if [ "$run" -eq "1" ] -a [ [ -f /tmp/start.Lck || -f /tmp/stop.Lck ] ]
then
....
else
...
fi
I am not understanding what is the issue here.

db2_num_rows
DB2_NUM_ROWS(3) 1 DB2_NUM_ROWS(3)
db2_num_rows - Returns the number of rows affected by an SQL statement
SYNOPSIS
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.
