Bash Script help...
by Jason Todd Slack-Moehrle 08 May '09

08 May '09

Hi All, I need to write a script that I will manually start (or a cron job in future) but I need it to do a number of things in order one after another. How do i do that so everything gets dont as the steps depend on each other. Example: cd /system_backups/ tar cvf apache-conf.tar /etc/httpd/conf/* gzip -v9 apache-conf.tar tar cvf apache-data.tar /var/www/* gzip -v9 apache-data.tar then last step... tar cvf <current_date>-system_backup.tar <all> the gzip files above gzip -v9 <current_date>-system_backup.tar scp <current_date>-system_backup.tar.gz user@10.0.0.1:/. etc...etc.... My questions: 1. How do I execute each statement and make sure subsequent statements are not executed until the previous is done? 2. How do I error check so if a step fails the script stops? 3. Since I run an SMTP Server on this box can I e-mail myself from bash the nightly results? 4. when I want to run the scp to send over the file to another machine for safety, how can I have it know the password to the machine I am scp'ing to? My mind is going crazy sort of with the things that I could do to protect myself in case of a system failure and making restoring easier. Can anyone provide insight for me? -Jason

Adding an 'official' CentOS image to the Amazon EC2 (Electronic Compute Cloud)
by Jason Aubrey 08 May '09

08 May '09

I'm starting to use the EC2 cloud (as are others) and noticed that all the available CentOS images seem to be of dubious origin. I think it would further the reputation and popularity of CentOS if it were represented in an official way. In case people aren't aware, when you create an AWS (Amazon Web Services) account there's a management console that shows a list of available images. Of this list, some are published by Amazon, others are uploaded anonymously, or you can upload your own. Given the dubious nature of an anonymous image and a lack of an Amazon image for CentOS, I'm left in the third camp - creating/bundling/uploading my own. Luckily I have the required 64 bit hardware to generate a 64 bit image! Selfishly I'd love to just start up an existing image published by centos.org but one's not available. Interestingly one is available from Amazon for both Fedora and Windows. Jason

Installing xfce on CentOS 5.3?
by James Pearson 08 May '09

08 May '09

I would like to install xfce from the "extras" repo - but when I run: yum groupinstall XFCE-4.4 I get: Warning: Group XFCE-4.4 does not exist. Also 'yum grouplist' appears to only show the base groups ... Is there anything else I have to do to install xfce? Thanks James Pearson
