Anyone know any good ports above 1000 that are usually open on default router firewall settings? I have to get around using sudo and my school's firewall for the secondary Minecraft server
lol, just kidding ... really I don't think there's a difference as far as intelligence goes ... your pic is probably a bigger factor for impressions, really
@NathanOsman no need to be in awe, there's a bunch of people that spend their days coming up with this stuff... if you think about it like that, it's actually shameful how unimaginative they really are
So the reason why i needed that question linked to new one, is because 1) it's dated 2) the answer there is too complex and requires installing weird libraries . . .which are not in ubuntu repos it seems 3) I've made an easy script on the new one
Second request is very very very optional . . . if you guys could just give me a few upgoats there that'd be great . . . I've been offering bounty on that question, and the high scoring answer only provided partial solution which didn't seem to quite work for me . . . So i wrote a script . . .besides, i cannot give bounty back to myself
@James Thankfully, there are other "clients", than the official python/docker piece-of-bloat.

@Nathan: When I type and I get those dots to show me and others that I am doing so, where are the dots meant to be? Because they were at the bottom before, and now that they are more in the middle for me they look uglier...
I have seen a number of users voting to close scripting questions as off topic. Is this the community consensus? Are bash questions not welcome here? How about other shell programming questions?
Shell script questions are usually better on U&L or AU. Even SU. SO is better for more hardcore programming issues. Simple shell scripts don't need to go there. They're on topic but why lose them in the thousands (millions) of SO questions.
Also, as far as I can tell you're already creating the user. You just have a few syntax errors and many quoting issues that will break your script if you give it bad input or input with whitespace.
Well, you run it by making it executable (chmod +x /path/to/script) and then executing it /path/to/script -u or /path/to/script -g or /path/to/script -b /path/to/backup/folder
for my first year CS I need to know Shell Scripting, but I'm really terrible at this. I wrote this script for example
#!/bin/bash
[ $(whoami) != "root" ] && echo "Run as superuser" && exit 1
while getopts "ugb: " opt; do
case $opt in
u)
read -p "Wat is de naam van de user die je wilt toevoege...
@MaartenWachters I tried to answer, fixing most of the issues. Make sure to read the comments as well. What are reate_softlink and mk_shared_folder? Where are they defined?
@MaartenWachters You see how he ends each block with ;; and the case with esac? You need to do that. Have you read any basic bash scripting guide? The manual? Anything at all?
@MaartenWachters I seriously doubt, that there are no clear instructions, about what the program is supposed to do. If that is indeed the case, please contact your lecturer/tutor for a clearer definition of the intended function.
@MaartenWachters As a university student myself: if the lecturer/tutor is indeed unwilling or incapable of providing clear task instructions, involve a higher authority, e. g. the course coordinator or higher up the faculty chairman.
Make sure to exploit all (reasonable) options with the lecturer/tutor themself, first. Make it clear to them, which part(s) of the task are unclear to you.
@MaartenWachters OK, I'm starting to understand. What he has done is give you the structure of the main program and then the functions you need to call. The things that look like foo(){ ... } are function. You need to add them at the beginning of your script and then you call them. For example:
@MaartenWachters AFAIK it's the same. The syntax might be different (don't know C#) but the concept should be the same. It executes a specific code block based on the value of a variable.
The syntax is :
case $var in
foo)
command1
;;
bar)
command2
;;
esac
@terdon Okay now I understand that. So if I were to have cases u, g, b, v , x and I want to run u, g , v. I'd do ./scriptname.sh -u -g - v for example?
In this case, the name of the backup folder. When getop options take arguments, they are stored as $OPTARG. So, to create a backup folder named foo wioth getopts, you would need something like this:
#!/bin/bash
while getopts "b: " opt; do
case $opt in
b)
## $OPTARG is whatever was given as an argument for -b
mkdir "$OPTARG"
;;
esac
done
Yup. Note that the value of $OPTARG depends on which of the options getopt is currently processing. So with script.sh -a foo -b bar, it will be foo when $opt is a and bar when $opt is b.
That tells me that the group terdon exists, has no password (the x in the second field), and has the GID of 1001.
@MaartenWachters In this case, it's just a simple way to check whether a group exists or not. Try it on your system with a group that exists and one that doesn't:
$ getent group root ## exists
root:x:0:root
$ getent group foobar ## doesn't
$
So, the script is using it to test whether the group it is supposed to add the user to exists.
Read what it prints. If the output of getent group groupname is empty (==""), it tells you that the group doesn't exist and exits. I don't speak Dutch but it seems like the error message tells you as much.
My fellow students and I complain over him vs eachother (he has the same name as me by chance) but I don't think any of us have actually filed a complained
@MaartenWachters Failing one class or the other is relatively normal, espc. in natural sciences and engineering and even more so during the first semester(s). Most students need to adjust to the different mode of teaching and leearning in university.
