Using ctltool to edit control files for UNIX images
Before you begin
You must have created the installable image.
To edit a control file
- Change to the /Install/instbin directory in the directory where the installable image is stored.
- Enter the following command:
ctltool.sh path/inputfile.ctl path/outputfile.ctl
The option path/inputfile.ctl represents the path to and name of the control file that you want to edit (the control file that was created with the installable image), and the option path/outputfile.ctl represents the path to and name of the new control file that you want to create.
For example, you create an installable image and store the image in a directory called installableimage. When you create the image, the installation utility creates a .ctl file named install.ctl and stores that file in that directory along with the image files. To edit this control file and create a new one in the same directory, at the command prompt, you would change to installableimage/install/instbin, and enter ctltool.sh installableimage/install.ctl installableimage/newfile.ctl.
The installation utility displays the first value stored in the control file. - Type a new value and press Enter to save your entry and display the next variable. To keep the existing value, press Enter. If you are changing a password variable, the value is encrypted in the new control file.
When the ctltool has finished displaying all the variables in the control file, the command prompt is displayed. Rename the new control file to install.ctl so that when you install the image, the installation utility uses the new control file. The installation utility looks for a control file named install.ctlto perform the installation.
