just like how linux has distributions, but i’ve been curious to see a unix distribution. i know linux is unix-like and all that but are there any distros that are purely based off unix?
Is Unix a distribution of Linux? How do you describe it?
I just realised that since the order of flags passed to the rm
command doesn’t matter, we could’ve, this whole time, been using rm -fr
instead of rm-rf
. So much easier to memorise, and funny as shit!
Hey folks,
I'm 71. Cut my teeth on punched cards and mainframes. TRS 80's using Basic, 4K mem, and audio tape for storage. Topped out using compiler languages for telecomms right at the pc/internet horizon 1990ish. Was pushed into mgmt & retired. Decent power user. Not dead yet.
I'm done licking Microsoft and Apple's boots. I will not be forced to have and use an OS vendor account to download compatible apps. I am not following the majority of mankind into the "cloud" abyss. Staying out of AI snares is going to be hard enough.
I got time to relearn from the metal up. Where do I go kids?

Hi all,
Need some advice on an issue i am facing install a package on several Solaris 11.4 U5 SPARC servers I am experiencing the same issue for all the servers. And i can't seem to figure out what is the issue is. And i have searched high and low for answers Hoping anyone had experienced the same and has a fix
i am unable to install the installation package provided to me by the vendor on these servers. The vendor has provided 2 files which either of which can be used to install the packge
When attempting to do any of the following in regards to installing the package, it produces the same error:
pkg: The image cannot be modified as it is currently in use by another package client. ``
root@Solaris_server:/tmp/agent_zipped# pkg install Agent-Core-Solaris_5.11_U4-20.0.1-21510.sparc.p5p
pkg: The image cannot be modified as it is currently in use by another package client.
root@Solaris_server:/tmp/agent_zipped#
i have attempted to do the following all of which produced the same error:
After unzipping the zipped file

Hi there,
So it seems the Iridium-Browser Devs are only sharing the source-code-tarballs from now on, and it is upto the end-user to install it on their machines.

I am not well-versed with anything apart from running a *.exe file.
Would appreciate any sort of help on this matter.
TIA.

Doing an assignment for college, and in my final part I have created a share called /nfs_shares/pub and the assignment says
All users must appear as the user s02_guest when performing operations on the share
Would anyone be able to help me with this? Any help is appreciated
Any suggestion where i should start learning unix
Hello everyone! I used to work for a medical software company for several years, then went on to work for a hospital. I have back end terminal access to our EMR server and sometimes I find it useful to run ping tests and check host file for specific tasks. I run into some issues as syntax and hotkeys work much differently from a standard Linux environment, and trying to understand if they are custom or emulating some old version of Unix.
Some background/info: When I was working for the company, they were using Unixware for their backend, then they switched to Scientific Linux, then CentOS. They use Linux kernel 3.10(custom), and many backend files use COBOL. When trying to view a previous command for example, you cannot simply press the UP arrow key, you have to use the hotkeys [CTRL]+[SHIFT]+[P]; to go forward in command history, the hotkey is [CTRL]+[SHIFT]+[N].
The reason I am posting is because when running a command like "ping *ip address*", I am unable to stop the process with [CTRL]+[C] and it keeps running until I force close the session.
I can try to provide more info or examples, but I am posting here because I am wondering if these are hotkeys for an older or specific version of Unix. If so, I may can find more documentation on how to navigate the system more cleanly. Thanks!
Hi all, need some advice if the way I am approaching this is right.
For some context: My organisation has bought ansible automation platform (AAP) I have not worked with AAP before, but in all my previous roles, I have worked with ansible My team consist of 5 of us managing unix servers There is another team in my organisation that Is tasked to work with the red hat team to develop the playbooks and the setup etc.
The setup has been completed and they have been developing playbooks for the past couple of months.
My team’s requirement: In my team there is a repetitive task we engage in. This task involves setting up servers, and going thru a checklist to ensure each “setting” is captured accurately.
Example: Part of the task is to ensure the Redhat server’s setting matches with the security standard of our organisation; which is based off CIS framework.
Other parts of the task include ensuring fire systems are created, ensure each filesystem meets a specific size, ensuring certain application are installed and running - you get the idea
Example: Section 2.3: Ensure Log audit filesystem is created and the size is 59GB
The playbook present: The playbook that is supposed to automate the above mentioned task was presented to my team recently.
First off, in the playbook for what I gather, the playbook is running a command to check
Using the above as an example;
Example: Section 2.3: Ensure Log audit filesystem is created and the size is 59GB
It is checking on the server is /var/log/audit exist If it does it returns a “True” Else if it doesnt it returns a “False”
This is essentially what is done throughout the whole script at the end when the script is finally completed all the return values are collected and output to a file which which is sent to the user via email and the user will read from and see which has failed and fix those which have failed
The file that is being sent to the user Will display the results for each section.
Example of file generated
Section 2.1: Pass Section 2.2: Fail
The user is then supposed to go and address those section which has failed
Script for each type of unix flavour and version is Being created since we have many types of unix OS and different versions and each has different “pre defined” values meaning for an example the size of the /var/log/audit filesystem size for Redhat 8 would be 59GB Redhat 9 would be 20GB AIX would be 70GB
The checklist is the same for all server, just that the specific values for each requirement is different
The issue I have and what changes I believe should be made
The current logic of what has been developed relies on “hard coded” values as such there will be multiple playbooks which my team have to manage
Suggestions: I have suggested to change the logic to be a dynamic logic, since all the serves have the same base requirement, only one playbook should be developed; the user provide a separate file which contains the value that needs to be true. The playbook reads off the separate and iterate through each requirement.
The current playbook only return true or false. Otherwise it does not do anything. If the value matches; then true If the value doesn’t match or anything else; false
suggestion: My suggestion is to incorporate the logic of error handling
Using the same example: If /var/log/audit exist return true Else if /var/log/audit does not exist return false Else if return error 400 or whatever error code, which can be generic or error specific
When I suggested these above points during a meeting with Redhat I was told by the Redhat employee thsg is assigned to us for ansible setup mentioned that I am over complicating things and the other team’s manager agreed with him and mentioned that i have a wrong understanding of ansible
From my understanding from past experience using ansible, programming and software engineering, I believe that my logic is pretty simple and common practice. And ansible is just an automation tool.
He has spent the past couple of months just to create 1 playbook for Redhat 8 in a testing environment, he stores the playbook on a gitlab The changes he makes on the playbooks are not following standard git practices. He Commits all the changes without version control
So I don’t know if the fella is pulling a fast one At the same time, I am worried that I might be making a fool of myself
In addition to that 3.I have not used AAP before I have only used Ansible Tower and the standard cli.
In thr past, I found using the UI much slower than CLI. It’s more of a preference as I am faster on terminal then on a UI.However when I asked if I could be able to use Ansible to run the playbooks on terminal, I was told the “UI” is more powerful and has a lot more features than the cli, which doesn’t make sense to me. And I wrong or am I right?
Do leave your suggestions, if I am wrong I am okay to accept it, part of a being an engineer, I will know better!
My concern is that since it will be my team of 5 using Ansible, and the Redhat employee is being paid to help us develop the playbooks; it should benefit us, with the playbook that is being developed, I rather write a batch script which is faster than python.
I am playing with OpenBSD's little ed(1) quiz program (fun!) and got stumped on this. Was wondering if anyone can explain if the semi-colons in the correct answer are just making this a one-liner, or if they are providing symantics that is new to me...
The question was: `go to line after third "PP" ahead'
And the provided answer was:
/PP/;//;//+1
I understand the double forward-slashes, but the semi-colons were a head scratcher. Of course, I use semi-colons all the time in various langs to put things on one line, but I had I feeling I wasn't grasping something.
Also, if the semi-colons are just making a one-line possible, does anyone know if there are any limitations on using this pattern in ed(1) everywhere? Meaning, can I chain a ton of goodies on one line, separated by semi-colons?
UPDATE: It should be noted that this does actually work.
I recently set up a SCO Openserver 5.0.7 on virtualBox following the tutorial (here).
Everything works fine except one thing, I have a significant access delay on network traffic. Indeed, when I ping my guest machine from my host machine I have 900 ms when I should have <1 ms.
Being still a novice on SCO Openserver 5.0.7 I am out of ideas to solve this problem.
let me know if someone, had this issue and solved it.

Was wondering if there was an elegant way (using Basic Regexp -- not Extended) to match a pattern (on a line), but not if contains another given pattern. This came up the other day in ed(1), and I wasn't sure how to go about it. The exact problem was:
find all urls in my file that matched `reddit.com'
for each of those, don't show any that match the string `comments'
It went a little like...
g/.*reddit\.com.*[^\(comments\)]/n
That didn't work, and not sure how to negate a word-pattern (instead of just a character list...)
Is there anything you'd like to see be improved upon when it comes to UNIX / UNIX-likes? I'm interested in operating system design and I'd like to maybe someday make an OS that is similar to UNIX, but also addresses its shortcomings.
Something around the lines of Unix clones made to look exactly like Mac or even complete forks of it-
I want to try something different, rather than messing around with linux trying to make it look like Mac.
Any ideas?
Pretty thanks in advance.
