Thanks.
Here's a slightly shorter version. Picky, picky, picky. Looking gift
horse in the mouth.
I try to start all my scripts with "set -eu" so that more bugs will be
detected.
"set -e" causes the shell to exit if a command unexpectedly fails.
That is, a command returns non-zero and was invoked in a non-test
context. Just what you want.
"set -u" tells the shell to treat a reference to an undefined
parameter as an error. It will make no difference in this script.
Until the script evolves more complexity.
| ===== update script =====
| #! /bin/bash

| # Program: update
| # Purpose: Perform 4-step apt-get update, dist-upgrade, autoremove and
autoclean

set -eu
| echo "Update:"
| apt-get update
|
| echo "Upgrade:"
| apt-get -y dist-upgrade
|
| echo "Auto-remove:"
| apt-get -y autoremove
|
| echo "Auto-clean:"
| apt-get autoclean
|
| if [ -e "/var/run/reboot-required" ]
| then
| echo
| echo "Reboot required by "
I think that this should be
echo -n "Reboot required by "
or
echo "Reboot required by"
| cat /var/run/reboot-required.pkgs
| fi
