recap is following the x.y.z versioning as defined below:

  • x (major) - Changes that prevent at least some rolling upgrades.
  • y (minor) - Changes that don't break any rolling upgrades but require closer user attention for example configuration defaults, function behavior, tools used to produce reports, among others.
  • z (patch) - Changes that are backward-compatible including features and/or bug fixes.


It is highly recommended to make use of a package to install recap is the easiest way to keep it updated whenever there is a new release.


recap is available from the main Fedora repository (spec file).

dnf install recap


recap is available from the EPEL repository (spec file).

yum install recap

Debian / Ubuntu

At the moment there is no public repository for Debian nor Ubuntu, two options are available:

Build a package

This repository contains the debian files required to build a deb package

These are the steps:

# Install all the packages required for building the package
apt-get update
apt-get install debhelper devscripts git -y

## For Ubuntu:
apt-get install equivs -y

# Create the working dir:
mkdir recap
cd recap

# Get the debian configs
git init
git remote add origin
git fetch --no-tags origin
git checkout -qf FETCH_HEAD
git submodule update --init --recursive
export LATEST=$( git log --format="%h" --no-merges -1 )

# Build dependencies
echo "yes" | mk-build-deps --install --remove debian/control

# Get upstream recap code
git checkout --orphan upstream
git reset --hard
git remote add upstream
git fetch -t upstream
latest_tag=$( git tag | tail -1 )
git archive ${latest_tag} -o ../recap_${latest_tag}.orig.tar.gz
tar -zxf ../recap_${latest_tag}.orig.tar.gz
git fetch --no-tags origin
git checkout ${LATEST} -- debian

# Build the package
debuild -us -uc --lintian-opts --profile debian

# Package will be created in ../recap_${latest_tag}-<RELEASE>_all.deb
# RELEASE comes from the changelog in the debian repository.

Manual install

Use the manual installation method.


  1. Install the required dependencies.
  2. Clone this repository: git clone
  3. Change into the new directory: cd recap
  4. Install the program: sudo make install

The information captured will be found in log files in the /var/log/recap/ directory.

About the locations of the scripts

The default location of the install is "/" it can be overriden with DESTDIR, the scripts, man pages and docs are installed under ""/usr/local" by default, this can be overriden with PREFIX. The following example is a common location for most of the distributions, this will install recap under /usr:

$ sudo make PREFIX="/usr" install 

This other example will install recap under your homedirectory but using the default locations for the script, i.e. under "~./usr/local":

$ make DESTDIR="~" install

The Makefile scripts attempts to detect systemd if so, the install option will install the systemd unit files. The install will not enable the timers, but it will show the commands required to enable each of the timers. When systemd is not detected the cronjobs will be installed.

Is up to each package distribution to follow their own best practices regarding enabling/disabling the timers on install/remove of the package.

Cron/Timers and Configuration


Multiple unit files are available to make use of timers, here the default schedules for the recap scripts:

  • recap (default every 10min)
  • recap-onboot (runs at boot time)
  • recaplog (default: Once a day 1am)

Enabling timers

Each one of the timers can be enabled with:

sudo systemctl enable recap.timer --now"
sudo systemctl enable recaplog.timer --now"
sudo systemctl enable recap-onboot.timer --now"

Disabling timers

Each one of the timers can be disabled with:

sudo systemctl disable recap.timer --now"
sudo systemctl disable recaplog.timer --now"
sudo systemctl disable recap-onboot.timer --now"


The cron file (/etc/cron.d/recap) is used to determine the execution time of recap and recaplog. By default the cron execution for recap is enabled to run every 10 min. and recaplog is expected to run every day at 1 am, but those can be adjusted as needed.


The following variables are commented out with the defaults values in the configuration file /etc/recap.conf which can be overriden.
