Changes the default values of environment variables as defined in various scripts.

Syntax

_tlr var-namereplace-valuefile-name...
 
_tlr var-namereplace-value -< file-list

The first syntax format processes one file at a time. The second processes a list of files read from a file.

var-name

A constant character string that identifies the environment variable whose value you want to modify.

replace-value

A constant character string that identifies the new default value of the environment variable.

file-name

The name of the file in which you want to modify the default value of the environment variable.

file-list

The name of a file containing a list of filenames in which you want to modify the value of the environment variable.

Example

Several of the scripts provided with OpenEdge name the DLC environment variable, as follows:

DLC=${DLC-/usr/dlc}

In this example, if the value of the DLC environment variable has been defined, the script uses the value of that variable. Otherwise, it uses /usr/dlc as the value of DLC.

To change the default value of the DLC variable to /tmp/dlc in a script named test.dat, use this command:

_tlr DLC /tmp/dlc test.dat

This command changes the environment variable line in test.dat from:

DLC=${DLC-/usr/dlc}

To:

DLC=${DLC-/tmp/dlc}
