set -f
set -- $variable
echo "$3"

If you are processing multi-line output from a command:

Code:
your_command | cut -d ' ' -f3

thanks for your reply

I stored the result in a variable

name=$(pgsql -c "select name from teacher")

$name is a single line
and equal to "name ------------ myname (1 row)"
I want to get the "myname" inside this variable

e.g.
If $name is "name ------------ Peter (1 row)"
I want to get "Peter" from the line

could you give me some suggestions? thanks

cdscp add directory directory-name attribute-name = attribute-value ARGUMENTS
The full name of the directory. The name of a particular attribute. Specify only one attribute at a time. See the cds_attributes file for the list of attributes that your application uses. attribute-value The value of a particular attribute.

If you enter a byte data type, you must enter an even number of digits in length. You can only enter pairs of hexadecimal values for user-defined attributes. DESCRIPTION
The add directory command adds a value to a modifiable, set-valued attribute (including application-defined attributes) of a directory. If the attribute does not exist, this command creates it. Usually, this task is performed through the client application. See the DCE Admin- istration Guide for more information about attributes. Privilege Required You must have write permission to the directory. NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE. EXAMPLE
To add the value ontario to the attribute myname of a directory named /.:/sales, read the cds_attributes file to verify that the attribute shown in the following display exists: OID LABEL SYNTAX 1.3.22.1.3.91 myname char Enter the following command to assign the value ontario to the attribute myname: cdscp> add directory /.:/sales myname = ontario RELATED INFORMATION
