How To List Installed Packages Sorted By Installation Date In Linux

Must read

This brief guide describes how to list installed packages sorted by installation date from command line in Linux and Unix-like operating systems. This can be helpful while you want to get the rpm packages update history such as when a package is installed, how many packages are installed on your system on a specific date and time and what packages you have installed on a certain date or time in your Linux box.

List Installed Packages Sorted By Installation Date In Linux

There are different way to list the packages on a Linux system by the date they were last installed or updated.

1. List installed packages sorted by install date on Arch Linux and derivatives

In Arch Linux and its derivatives like Manjaro Linux, you can list the installed packages sorted by installation date using the following command:

$ expac --timefmt="%Y-%m-%d %T" '%lt%n'|sort -n

Sample output from my Arch Linux box:

2020-12-15 13:02:09 iana-etc
2020-12-15 13:02:10 filesystem
2020-12-15 13:02:10 linux-api-headers
2020-12-15 13:02:12 tzdata
2020-12-15 13:02:14 glibc
2020-12-15 13:02:17 gcc-libs
2020-12-15 13:02:20 ncurses
2020-12-15 13:02:20 readline
2020-12-15 13:02:21 acl
2020-12-15 13:02:21 attr
[...]

List installed packages sorted by install date on Arch Linux

The above command will list all installed packages sorted by the install date in Arch Linux. You can also list the 10 last installed packages using command:

$ expac --timefmt="%Y-%m-%d %T" '%lt%n' | sort | tail -n 10

If expac is not installed on your Arch Linux system, run the following command to install it:

$ sudo pacman -S expac

2. Get the RPM packages update history on RHEL, CentOS, Fedora

In Fedora, RHEL, and it’s clones like CentOS, run the following command as root or sudo user to list the installed packages history:

# rpm -qa --last

Sample output from Fedora:

Also, you can use this command to list the installed packages sorted by installation date or time:

# rpm -qa --qf '%{INSTALLTIME} (%{INSTALLTIME:date}): %{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}n' | sort -n

To find out the installation date of a specific package, for example rsync, run:

# rpm -q --last rsync

Sample output:

rsync-3.2.3-1.fc33.x86_64 Monday 19 October 2020 11:37:47 PM

3. View package update history on Debian, Ubuntu systems

In Debian, Ubuntu and all APT based systems, you can list the installed packages sorted by install date/time using the following command:

$ grep " install " /var/log/dpkg.log

Or,

$ grep install /var/log/dpkg.log

Or,

$ grep installed /var/log/dpkg.log

Sample output from Ubuntu:

[...]

If log rotation is enabled, you can view the previous install log using command:

$ grep " install " /var/log/dpkg.log.1

To view the archived logs, run:

$ zgrep " install " /var/log/dpkg.log.2.gz

Please note that if you have enabled log rotation, the logs will be deleted over time. So, there is no reliable method to list the installed packages by install date in your Debian or Ubuntu systems.

These are a few methods to find the package update history in Linux. You know now what packages are installed and when you’ve installed them on your Linux system. Hope this helps.
