I don't know sqlplus and therefore I don't know what effect you hope to achieve. I also don't understand your need to use use backquotes. But try doubling the backslash.
Code:
bash-3.1$
bash-3.1$ abc="kkjhkjhkjhkj"
bash-3.1$ echo ` echo a\b v\$abc`
ab vkkjhkjhkjhkj
bash-3.1$ echo $( echo a\b v\$abc)
ab v$abc
bash-3.1$ echo ` echo a\b v\\$abc`
ab v$abc
bash-3.1$
bash-3.1$
"Is there any substituation of last command or script syntax which can be used as a user. As far I know the "last" command is being used to display information about previous logins. A member of adm group or the user adm can execute it only.
Thanks in advance for your usual help.

hi,
I have to execute this line below from within a shell script; simply backquoting it is not doing the trick; it is mangling up all the options; but when i type it out on a command line, it executes cleanly. Please help me in getting this right;

Hi,
What is the actual difference between these two? Why the following code works for process substitution and fails for command substitution?

But,
while IFS='\n' read -r... (3 Replies)

Hey, guys!
Trying to research this is such a pain since the read command itself is a common word. Try searching "unix OR linux read command examples" or using the command substitution keyword. :eek:
So, I wanted to use a command statement similar to the following.

LEARN ABOUT PHP
oci_set_action
OCI_SET_ACTION(3)OCI_SET_ACTION(3)oci_set_action - Sets the action nameSYNOPSIS
bool oci_set_action (resource $connection, string $action_name)
DESCRIPTION
Sets the action name for Oracle tracing.
The action name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement
is executed.
The action name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitor-
ing such as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
PARAMETERS
o $connection
-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $action_name
- User chosen string up to 32 bytes long.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Setting the action
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the action
oci_set_action($c, 'Friend Lookup');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the actions
// being performed:
sqlplus system/welcome
SQL> select action from v$session;
NOTES
Note
Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.
Tip
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack-
age. This is less efficient than using oci_set_client_info(3).
Caution
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
enabled.
