Basesystem should be in every installation of a system, and it should never be removed. Using Basesystemīasesystem defines the components of a basic Fedora system (for example, the package installation order to use during bootstrapping). These commands will work on all Linux distributions that supports ext4 filesystems. Sample output: Filesystem created: Thu May 20 17:31:06 2021ĭisplay filesystem creation date and time in Linux It will display when the file system was originally created. Replace /dev/sda1 with correct hdd drive partition. Or, # dumpe2fs /dev/sda1 | grep 'Filesystem created:' Or, # tune2fs -l /dev/sda1 | grep 'Filesystem created:' # fs=$(df / | tail -1 | cut -f1 -d' ') & tune2fs -l $fs | grep 'Filesystem created' Now, run any one of the following commands as root user. In such cases, you can find the installation date like below. Check Filesystem Creation DateĪs stated, sometimes, you might have deleted the logs (or enabled log rotation). You still can find out the installation time of your Linux OS by verifying filesystem creation date as shown in the following section. What If the logs are deleted already? No problem. Sample output: Jul 2 10:29:10 ubuntu systemd: Starting Flush Journal to Persistent Storage. On Debian, Ubuntu and other DEB-based systems, look in the "syslog" entries to get Linux OS installation date and time $ sudo head -n1 /var/log/installer/syslog Check Syslog Entries On Debian-based systems I have 3 Arch Linux systems (One host and two vms) over the years, and I've never had to "reinstall" even once. And, I am sure I am not going to reinstall it anytime soon. It works perfectly well without breaking anything. Sample output from my Arch Linux system: Running 'pacman -r /mnt -Sy -print-format=%s -cachedir=/mnt/var/cache/pacman/pkg -noconfirm base sudo grub wireless_tools wpa_supplicant wpa_actiond netctl dialog os-prober'Īs you see in the above, I am still using my first installation from May, 05 2016.Įven though Arch Linux is rolling release model, I have never had to reinstall Arch Linux. If you use Arch Linux and its derivatives like EndeavourOS and Manjaro Linux, you can easily find how long have you been using it without a reinstall by analyzing the pacman logs as shown below. Try it and see what I mean.Find exact Linux installation date and timeĪs you can see in the above outputs, the installation date and time of my Fedora Linux desktop is May 20, 2021. The reason why I don't want to buy this is because I will never need it, but, if you need the compatibility and/or features, this product is worth its cost. I haven't seen many other programs with such large compatibility. It's great that this supports some of the less popular operating systems just as much as the popular operating systems. It's not just Mac and Windows, but many other operating systems. You might not only get this for the features, but you might also get it for the compatibility of the installs. Some installers provide optional splash screens, this one does, too. The average user can be frustrated removing something that does not have an uninstaller by means of traditional drag-and-drop to the trash/recycle bin, so it's great to include one in your install. There are also things like an uninstaller which many other programs that create installers never include. Opening it, I find that there are many features in this tool that are typical among installers that are necessary (ReadMe, License, etc.). The installation time might be long enough to pop a small bag of popcorn, but it's worth the wait and you only have to do it once. But, it's free to try the demo, so why not? When I first looked at it, even I thought it was too expensive. The first thing everyone looks at is price before downloading it.
