I’ve been diving into configuring my Ubuntu Server 20.04 lately, and I ran into this little hiccup that’s driving me a bit crazy. So here’s the deal: I’m trying to get the `date` command to display the time in a 24-hour format when I use it in the shell. You know, that clean and straightforward military time vibe? It just feels a lot more organized that way, but I can’t seem to get it right.
I thought it would be as easy as flipping a switch, but no luck so far. I’ve tried a few things that usually work for basic commands, like just typing `date` and expecting it to have an option or something. But instead, I keep getting the standard 12-hour format, which isn’t what I’m aiming for. I looked it up a bit and found some snippets of info, but they were more like guidelines rather than straightforward instructions.
What I really want is to make sure every time I run the `date` command, it spits out the time in 24-hour format automatically, without me having to fuss over it every time. I mean, I’ve also heard about using the `date` command with different format options – but honestly, how do I make it stick? Is there a way to set this as a default for all my terminal sessions? Or do I have to put in a specific command each time I launch the shell?
If anyone out there has run into this before or knows a simple way to set it up, I’d really appreciate the help! Maybe share your own experience or how you configured it? Also, if there are any pitfalls or things to watch out for, that would be super useful too. Sometimes I feel like these little tweaks can be much more complicated than they need to be. Thanks in advance for any tips or guidance you could throw my way!
To set the `date` command to always display time in a 24-hour format on your Ubuntu Server 20.04, you can customize your shell configuration. One effective way to achieve this is by creating an alias in your shell’s configuration file (like `.bashrc` if you’re using bash). Open your terminal and run the following command to edit the file:
nano ~/.bashrc. Once you’re in the editor, scroll to the bottom and add the line:alias date='date +%H:%M:%S'. This command will set the alias for the `date` command so that every time you use it, it will display the time in the desired 24-hour format with hours, minutes, and seconds. After making the changes, save the file, and runsource ~/.bashrcto apply the new settings immediately.Alternatively, if you prefer not to use an alias, you can directly specify the format every time you use the command by typing
date +%H:%M:%S. However, the alias method is more convenient as it saves you from needing to remember the format string. Keep in mind that if you ever want to revert to the default behavior, you can simply remove or comment out the line in your `.bashrc`. Additionally, watch for any typos or format specifiers, as these can throw off the command’s output. By using this approach, you can ensure a consistent view of time in the clean and organized format you desire without the extra hassle each time you open a terminal session.Getting the `date` Command to Show 24-Hour Format on Ubuntu Server 20.04
First off, I totally get where you’re coming from! Changing the `date` command to show time in 24-hour format is actually pretty straightforward once you know the steps. Here’s how you can do it:
Using the Date Command
When you use the `date` command, you can specify the format you want. For 24-hour time, you can type:
This will show the current time in 24-hour format (e.g., 14:30 for 2:30 PM).
Making It Stick
If you’re looking to make this your default output every time you launch your terminal, you can set an alias in your shell configuration file. Here’s how:
~/.bashrcif you’re using Bash):CTRL + X, thenYto confirm, andEnterto save.)Common Pitfalls
Just a couple of things to watch out for:
~/.bashrcfile, as this could cause errors in your terminal.That should do the trick! Now when you type `date`, it’ll display the time in a nice 24-hour format. Hope this helps you out!
