| [loc=]string and method=methname |
Required. Specifies a location and access method for obtaining the value of the variable. The method= can be omitted with the file name or location ends in .rpm, .par, or .sh. See also information on built-in rpm access methods in the RPM user's manual. | |
| name=wildcard expr | Optional. Use this to choose a subset of Public variables which match the wildcard or "Glob" expression. | |
| Contained Tags | None. | |
| Related Tags | Save tags are ignored unless they appear within an Action section of the Public section. For methods that write to a shell script or external program, an implicit Import is done on the script's output. It simply needs to print lines of the form "variable=newvalue" on stdout to update the variable in the form. Although Private variables will never be passed to the external program, their values can be updated in the other direction by the output of the shell script. | |
| Examples | The examples for Action also illustrate some uses the Save tag. | |
