lrun

lrun is a command-line utility found on some Unix-like operating systems, notably those derived from Solaris. Its primary purpose is to run a specified program in a separate session, often in a non-interactive environment. This means that a program launched with lrun will not be directly tied to the user's current terminal session. This can be useful for background tasks, scheduled jobs, or when a program needs to run independently of the user's login status.

The exact functionality and options of lrun can vary slightly depending on the specific system it is implemented on. However, common usage typically involves specifying the command to be executed. Some versions might offer options for controlling the environment in which the program runs, such as setting specific environment variables or redirecting standard input, output, and error streams to files. The utility's design allows for programs to continue their execution even if the user who initiated the lrun command logs out or closes their terminal. This isolation makes it a tool for ensuring the persistence of certain processes. It is not as widely known or used as alternatives like `nohup` or `screen`, but it serves a similar purpose for process management in specific contexts.
