LR_ENVIRONMENT.IN(1) LogReport's Lire Documentation LR_ENVIRONMENT.IN(1)NAME
lr_environment - Export Lire configuration in shell script form
SYNOPSIS
eval `lr_environment`
DESCRIPTION
The lr_environment command is used to import the Lire configuration in Lire shell scripts.
All of Lire configuration variables will be written in a format that can be evaled by the shell.
Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.
The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
