Hello,
When I run it with multiple files as you guided yesterday, output barisprep.sql seems like (just excerpted related field):
Instead of bold video_id in line including SELECT, I am trying to insert value of related video_id grabbed from the table for related $1 at each line....
Let's say
If video_id of Mr.SmithGoes.to.Washington.mkv is 655, I am trying to replace video_id text shown in bold as 655
If video_id of Human.Traffic.mkv is 1233, I am trying to replace video_id text shown in bold as 1233
i am using the below script and trying to move files in that directory in that pattern to archive. But it doesn;t seem to take the metacharacters. Please sugggest.

Hi all,
I'm bit new to the advanced bash shell scripting.
When I'm looking at some of the existing code in my organization, got confused with a few variable definings.
For ex:

var3={xyz:-$var2}
In above, 1st and last lines are confusing me.... (4 Replies)
I'm a bit confused about the term ‘environment variables'.
Within your shell you can set two types of variables:
1. Shell variable - affecting functionality within your shell
2. User defined variable
When using the ‘export' command on a variable you make sure it's being inherited by new sub... (2 Replies)

dblink_exec
DBLINK_EXEC(3) PostgreSQL 9.2.7 Documentation DBLINK_EXEC(3)NAME
dblink_exec - executes a command in a remote database
SYNOPSIS
dblink_exec(text connname, text sql [, bool fail_on_error]) returns text
dblink_exec(text connstr, text sql [, bool fail_on_error]) returns text
dblink_exec(text sql [, bool fail_on_error]) returns text
DESCRIPTION
dblink_exec executes a command (that is, any SQL statement that doesn't return rows) in a remote database.
When two text arguments are given, the first one is first looked up as a persistent connection's name; if found, the command is executed on
that connection. If not found, the first argument is treated as a connection info string as for dblink_connect, and the indicated
connection is made just for the duration of this command.
ARGUMENTS
conname
Name of the connection to use; omit this parameter to use the unnamed connection.
connstr
A connection info string, as previously described for dblink_connect.
sql
The SQL command that you wish to execute in the remote database, for example insert into foo values(0,'a','{"a0","b0","c0"}').
fail_on_error
If true (the default when omitted) then an error thrown on the remote side of the connection causes an error to also be thrown locally.
If false, the remote error is locally reported as a NOTICE, and the function's return value is set to ERROR.
RETURN VALUE
Returns status, either the command's status string or ERROR.
EXAMPLES
SELECT dblink_connect('dbname=dblink_test_standby');
dblink_connect
----------------
OK
(1 row)
SELECT dblink_exec('insert into foo values(21,''z'',''{"a0","b0","c0"}'');');
dblink_exec
-----------------
INSERT 943366 1

(1 row)
SELECT dblink_exec('myconn', 'insert into pg_class values (''foo'')',false);
