The lpm command is available on Linux systems to setup and run externally-provided software from a Local Software Package environment. It allows users to execute an application or a newer version of system software which is present in alternative locations called repositories. Two repositories are supported: unc, for general ITS supplied packages; and thl, for Tar Heel Linux supplied packages.
lpm allows a user to run commands using a specific version of a package. Enabled packages persist over logins. There are options to list available packages, download packages, and load packages into a user’s environment. If a package’s default version is given, lpm will load the highest numbered version of the package it finds in the repository.
Users can list the names of packages which have been added to their environment, get the names of a package’s binaries, and get general information about a package.
lpm’s software packages are stored on the Red Hat Satellite Server, referred to below as the Global Repository. lpm lets an administrator download packages from the Global Repository into a machine’s Local Repository. From there, users can load specific packages into their personal environments.
system-administrator-specified packages constitute a default set of packages users will get on login. It consists of packages listed in repository .pkgrc files (e.g. /opt/unc/.pkgrc, /opt/rh/.pkgrc). If a .pkgrc file does not exist, no packages found in the repository are included.
user-specified packages are specific to individual users. Packages listed in a file named “~/.pkgrc” are included in the user-specified package set.
User-specified packages take precedence over system-administrator-specified packages; both types take precedence over system packages.
avail – list packages available for loading into the user’s environment
load – load a package into the user’s environment
unload – unload a package from the user’s environment
query – list packages loaded into the user’s environment
bin – print the names of a package’s binaries
lib – print the names of a package’s libraries
env – print information about the local package space environment
refresh – refresh the user’s local package space environment
list – print the names of packages available for downloading from a global repository
info – print information about a package
install – install a package from the global repository*
erase – delete a previously installed package from the local machine*
sysload – load a package into all user environments*
sysunload – a package from all user environments*
verify – verify that package environment is correct*
* You must be root to run this command
list all installed packages on the local system
list packages enabled in the user’s environment
lpm load ne-3.0.1
add the ne 3.0.1 software package to the user’s environment
lpm load ne gcc
add the default versions of the ne and packages to the user’s environment
lpm unload ne
remove the default version of the ne software package from the user’s environment
re-reads the system and user .pkgrc files. Useful if a package was added in one window, and you want it reflected in anther window’s environment.
print the lpm version number
If you have not already done so, install the its-release package that grants access to ITS’s yum repository.
Then install as follows:
% sudo yum install lpm-unc
Logout and back in. Then you can begin using the local package management system.
