[SOLVED] updating google chrome

rurio --

I don't much cotton to the idea of auto-updating software on my Machines.

Been there, done that on an old RH Box and it made a mess and I wasn't sure how the mess was made nor what that mess was and finding and fixing it caused a four-hour outage on a customer's mission-critical Box.

Not to mention the disasters I see from time-to-time on customer's Windows Boxen.

Anyway, it's something I don't do any more if I can prevent it.

Another thing is I try to not write content to the HDD until I am ready to do something with it.

Enough philosophizing ... Let me say first of all that I really do like your google-chrome.SlackBuild script ( latest-chrome Version 1.3.3 )

It is much easier to use than the official one in Slackware64/extra/google-chrome/ because it checks for updates and it does the downloads automatically ( lazy-ole-me likes that

).

And I REALLY like the fact that I can build the package as a 'joe' ( no need to be root ).

Thanks for asking the question which made me look closely at latest-chrome to see what it actually does.

Now that I've looked at latest-chrome, there is no reason it couldn't be run as a cronjob.

My only suggestion would be to add an optional 'report-only' mode ( which is what I am after )

Something like this ...

Code:

let report_only = 0 ;   # default is 'build the package' but allow an override
#
# ... update_available is tested ...
#
if ( update_available == 0 ){ 
   if ( report_only != 1 ) {
      print "google-chrome is already installed" ; 
   } 
   exit 0 ;             # RetCode == 0 -> google-chrome is up-to-date
} 
#
# if running in 'report only mode' exit here
#
if ( report_only == 1 ) {
   print "google-chrome ($VERSION) is available"
   exit 1 ;             # RetCode == 1 -> an update is available
}

This way, I would get reminders until I am up-to-date but the latest-chrome won't bother to build the Package until I am ready for it.

But I don't want to mess with your script so that I can update it if ever needs an update.

That's why I created and installed `check-version-xml.sh` as a cronjob.

OTOH, if you want it, below is a patch which adds a -r ( or --report-only ) commandline arg to latest-chrome

When run in report-only mode, latest-chrome will simply check the version and ... if up-to-date then exit( 0 ) else { print a message ; exit( 1 ) }

Finally, speaking of cronjobs, I received an email from check-version-xml.sh this morning: google-chrome-53.0.2785.113-x86_64-1 is available

HTH ...

I also don't like automatic package updates....

I have the following bash script in my daily crontab which is very basic (for sure it can be improved!) but it works as I like

.
It makes the following actions:
- get the latest google chrome version from the web (.deb file)
- check is the installed version is updated
- if not it generates the new slackbuild
- logs all the activities in a log file
- finally it informs the user about the new slackbuild (which is ready to be installed - manually - using upgradepkg)

It requires to have in the INSTALL_DIR the standard slackbuilds files (README, google-chrome.SlackBuild, slack-desc)

Code:

#!/bin/sh
INSTALL_DIR=/usr/local/chrome_update
LOG=/var/log/google_chrome_update.log

if [ ! -d $INSTALL_DIR ]; then
  echo "$(/bin/date), ERROR: directory $INSTALL_DIR not found!" >> $LOG
  exit 1

fi

if [ -z "$GC" ] || [ ! -x "$GC" ]; then
  echo "$(/bin/date), WARNING: Could not detect an installed version of Google Chrome" >> $LOG
  exit 1
