Fcron-3.2.1

Config Files

/etc/fcron.conf, /etc/fcron.allow, and /etc/fcron.deny

Configuration Information

There are no required changes in any of the config files. Configuration information can be found in the man page for fcron.conf.

fcron scripts are written using fcrontab. Refer to the fcrontab man page for proper parameters to address your situation.

If Linux-PAM is installed, two PAM configuration files are installed in etc/pam.d. Alternatively if etc/pam.d is not used, the installation will append two configuration sections to the existing /etc/pam.conf file. You should ensure the files match your preferences. Modify them as required to suit your needs.

Periodic Jobs

If you would like to setup a periodic hierarchy for the root user, first issue the following commands (as the root user to create the /usr/bin/run-parts script:

cat > /usr/bin/run-parts << "EOF" &&
#!/bin/sh
# run-parts:  Runs all the scripts found in a directory.
# from Slackware, by Patrick J. Volkerding with ideas borrowed
# from the Red Hat and Debian versions of this utility.

# keep going when something fails
set +e

if [ $# -lt 1 ]; then
  echo "Usage: run-parts <directory>"
  exit 1
fi

if [ ! -d $1 ]; then
  echo "Not a directory: $1"
  echo "Usage: run-parts <directory>"
  exit 1
fi

# There are several types of files that we would like to
# ignore automatically, as they are likely to be backups
# of other scripts:
IGNORE_SUFFIXES="~ ^ , .bak .new .rpmsave .rpmorig .rpmnew .swp"

# Main loop:
for SCRIPT in $1/* ; do
  # If this is not a regular file, skip it:
  if [ ! -f $SCRIPT ]; then
    continue
  fi
  # Determine if this file should be skipped by suffix:
  SKIP=false
  for SUFFIX in $IGNORE_SUFFIXES ; do
    if [ ! "$(basename $SCRIPT $SUFFIX)" = "$(basename $SCRIPT)" ]; then
      SKIP=true
      break
    fi
  done
  if [ "$SKIP" = "true" ]; then
    continue
  fi
  # If we've made it this far, then run the script if it's executable:
  if [ -x $SCRIPT ]; then
    $SCRIPT || echo "$SCRIPT failed."
  fi
done

exit 0
EOF
chmod -v 755 /usr/bin/run-parts

Next, create the directory layout for the periodic jobs (again as the root user):

install -vdm754 /etc/cron.{hourly,daily,weekly,monthly}

Finally, add the run-parts to the system fcrontab (while still the root user):

cat > /var/spool/fcron/systab.orig << "EOF"
&bootrun 01 * * * * root run-parts /etc/cron.hourly
&bootrun 02 4 * * * root run-parts /etc/cron.daily
&bootrun 22 4 * * 0 root run-parts /etc/cron.weekly
&bootrun 42 4 1 * * root run-parts /etc/cron.monthly
EOF

Boot Script

Install the /etc/rc.d/init.d/fcron init script from the blfs-bootscripts-20210110 package.

make install-fcron

Finally, again as the root user, start fcron and generate the /var/spool/fcron/systab file:

/etc/rc.d/init.d/fcron start &&
fcrontab -z -u systab
