Is it safe to say that I can run the command rsync -avv --inplace --no-whole-file "$1" "$destDir" and rsync will try to copy only the file that failed to copy because of an input/output error?
This would use rsync's delta-transfer algorithm and since only one file (i.e. file.pdf) failed to copy, only the file that failed to copy should be transferred. I don't think --inplace` is necessary here as there is no existing file. As for --no-whole-file, if I use --whole-file instead, will it still be only the file.pdf file that failed to copy that will be transferred except that the whole file will be transferred.
Basically, I want to confirm whether rsync -avv --inplace --no-whole-file "$1" "$destDir" command will only transfer the (whole) file.pdf file? I think I can use rsync to manually copy that single file, but I want to rerun the script which contains rsync -avv --inplace --no-whole-file "$1" "$destDir" with any necessary modifications to the rsync command in the script.
Suppose I have a file containing lines of text. I want to insert those lines, all in one line, with spaces in between, inside a command. What's the easiest way to do that?
So for example, a file containing:
foo
bar
and then I want to insert it after (say) the command ls. To make ls foo bar.
You know, there is a whole site for questions just like this. Where you can explain what you need and give examples and where we don't need to draw out the details step by step like this in chat. Hint, hint :P
@terdon Yes, I could ask a question. But there are many questions already, and I thought it was something simple that could be taken care of in chat. But sure, I can ask a question.
Suppose I have a file containing lines of text. I want to insert those lines, all in one line, with spaces in between, inside a command. What's the easiest way to do that?
But anyway, that won't put the contents of the file in one line with spaces in between. It all comes down to the contents of Faheem's file, the exact command he wants to run and details like that
@AndrasDeak No. I never use xargs so I don't know its options off the top of my head. I could just see that the one you gave me was giving the flag to ls not xargs
@AndrasDeak I have a rough idea what a container is. I think it is like a Python virtual environment, in that a container isolates whatever is created inside it, from the environment outside of the container. Not sure what the difference between a container like Docker and a Python virtual environment is.

@AndrasDeak You might recall that some months ago we were discussing using TikZ to complete PDF forms. And you kindly provided example code for grids with (0,0) on the bottom left (as I recall) and posted it here. Do you happen to recall what the final version of your code was, and do you have it handy? And if not, do you remember what you posted back then?
I have a new form to fill, and of course I can't find your code, which I saved and tested.
Of course, this is another reason why it's good to ask questions as questions...
disk names wouldn't remain constant between operating systems right? for example if I have /dev/sdf failed on one install and then boot a live disk there is no guarantee it will still be /dev/sdf?
A vulnerability would allow a PDF not to execute the PDF (as if it were an executable itself), but it would cause the reader to execute a piece of code contained in the PDF.
That’s only for code execution vulnerabilities, which are a subset of vulnerabilities...
But even seemingly innocuous tools such as strings have ended up with vulnerabilities.

The command hg fold in the Evolve extension isn't ...
I want to clarify my earlier statements about (not) discussing politics in this room. I'm personally biased from seeing heated and sometimes violent "discussions" around politics. I am not against civil, constructive discussions on any topic, including politics. As with any Stack Exchange site, this chat room should be civil and abide by the Code of Conduct. Thanks!
People pay more attention to US politics because they have a zillion nuclear bombs, a huge army, and hundreds of bases, so people are terrified of what they might do.
@AndrasDeak That's like 2 billion people or something. Or will be soon. Also, nuclear fallout spreads with the wind and stuff. It's one planet, remember.
They really should get the kindergarteners to repeat "ONE PLANET, ONE PLANET" at the beginning of morning school. Perhaps it would go in.
@AndrasDeak Well, that's larger than Denmark, New Zealand and Austria, at least.
@FaheemMitha no problem! and if there's anything important, it should be in the question, of course. I'm half distracted, so I'll see if I can come up with something better. Head to bed; get some rest :)
@JeffSchaller I had to dispute the charge for those weights I ordered. That company is pretty sus. They sent me an email saying my order had shipped but included no tracking info, and then shortly after they updated their website saying that they had issues with the suppliers and were unable to fulfill any orders and everyone would get a refund. Which they never actually did
@jesse_b oooph, sorry to hear! My wife went through something similar with a shirt. They sent the wrong shirt, but when we went to return it, they offered all sorts of crazy alternatives, eventually landing in us keeping the shirt and getting a refund.
I once ordered spaghetti and meatballs and they sent me linguini and meatballs, something about the shape of linguini noodles really creeps me out so I can't eat them. I called them to complain and the guy yelled at and insulted me because "linguini and spaghetti are the same thing"
He thought I was just trying to get a free meal out of them so he sent the driver back to pickup my uneaten food
@jesse_b I'm trying to remember; they were so odd they didn't stick. I think one was: keep the shirt and have some amount of credit towards a different item; I think another might have been (keep the shirt) and have a partial refund. I remember they really didn't want the item to be returned. Probably a ding on their Amazon rating somehow.
yeah, it was weird, which raised our already raised suspicions, and made me wonder (among other things) if it was to remain in good standing with Amazon
It already bothers me that amazon often makes you pay for ups pickup on returns. I didn't drive to a store and buy the wrong item so I shouldn't have to drive to a storefront to return it
I don't know, as I said it's not intuitive to me. If Stephen were here I bet he would have an explanation of why it is actually the intuitive way and I'm probably just wrong :p
In fact I think someone has explained it to me before and I am just forgetting
I'm thinking - is the opposite of whatever the default state of the shell option is, and + is the opposite of whatever the the modified state of the shell option is.
@BlackPanther + turns off (disables) only because - turns on (enables), and - enables because that's the common character that is used for command line options, and generally speaking, options enables features or behaviors.
The alternative would be e.g. set -o nohistory (as is done with options within the vi editor).
@jesse_b I am. But I stepped it up a notch. I live right by a nature reserve/bird sanctuary, and there's a nice walk of almost exactly 5 km that I do in about 55 minutes ever morning at 7 am.
@Kusalananda nice, I never understood "bird watching" but I get a lot of blue jays, robins, and wood peckers in my back yard and they are always fascinating to watch
I don't always copy and paste code from the internet but when I do I su do
as for the sh -c part, the environment will be different between /bin/sh and whatever your default shell is so maybe it's just trying to check if that is available in sh's environment
@BlackPanther I see no real reason to run that command in a sh -c shell. Unless your current shell is not a POSIX shell at all (such as tcsh or fish). Then it would make sense.
I'm using a command line program that gets values from shell environment variables. Why would this command line program stop using it's environment variables for configuration?
In other words, what is causing the environment variables to stop being used by the program. RESTIC_REPOSITORY and RESTIC_PASSWORD were not used even though I opened a new terminal window/tab.
@jesse_b Wait, sh or bash creates a new (sub-shell), does sh -c also create a subshell? I assumed sh -c just executes a command using the shell (or as a shell)? I'm trying to find an analogy/comparison to sh -c using su -c which executes a command as the root user.
There are this two names: a subshell and a child-shell.
Yes, a child process will be started by any of this:
sh -c 'echo "Hello"'
( echo "hello" )
echo "$(echo "hello")
echo "hello" | cat
Are all equivalent and share the same name? Do all share the same properties?
POSIX has this definitio...
@Kusalananda I set them using export RESTIC_REPOSITORY="/path/to/restic/repo" && export RESTIC_PASSWORD=password in the same terminal window that I ran sudo restic backup ...
All tests show that RESTIC_REPOSITORY and RESTIC_PASSWORD were exported.
@Kusalananda The same environment as in the same window I run restic in?
It's an anomaly because restic snapshots works, which shows that when using the snapshots command restic sees the environment variables RESTIC_REPOSITORY and RESTIC_PASSWORD. However, when using the backup command restic does not see them.
@JeffSchaller Interesting? Meaning you can pipe it to sh or bash?
@MichaelHomer Am I missing something? Gilles answer explains (very well) what a subshell is, the answer doesn't say whether a subshell is the same as a child shell.
@JeffSchaller Cool. declare is also available to the user which means we can also declare variables using the syntax declare -x RESTIC_REPOSITORY=/path/to/restic/repo/
@JeffSchaller I will, thanks
@Kusalananda Really? su switchers user, so su also uses a different environment to the user.
I expected sudo to just run a command using root privileges, meaning that calling sudo does not change the current environment
@Kusalananda Oh you said clear
@Kusalananda I've not seen the env command in a long time. I think it runs a command line in a modified environment. Thanks.
Unfortunately I had to run restic by specifying the repo on the command line and entering the password interactively. When I get the chance to try sudo with env, I will.
If I want to upload a work project to a remote git repository, is it bad if I change the author and email from my work credentials to the git credentials I use on my personal laptop?
I don't understand the following shell while loop:
git rebase -i --rebase-merges --root; while true; do git commit --amend --no-edit --author "Theodore R. Smith <theodore@phpexperts.pro>"; git rebase --continue; done
The only way for a while loop to stop executing is if the while loop variable evaluates to false. So why is it that the above while loop does not cause an infinite loop?
That would let people using git log to see your updated credentials, but your original creds would still be there. And github (and maybe others) don't support .mailmap as far as I know.
@BlackPanther you literally just create a .mailmap file. It doesn't touch the commits, only the presentation in git log.
That's why I asked what exactly you need. Mailmap is only a thin cover that anyone can peek under. Like having a name tag that distracts people from looking at your face. Whoever wants to look at your face can still do it. And github (and maybe other services) don't support having a name tag so people will only see your face there.
If you want to actually erase your work credentials then mailmap won't work. If the original data is not a secret, only inaccurate, then mailmap can work.
@AndrasDeak I see. I wanted people who view my project to not see that the project was done on my work laptop but I was concerned about whether this is ethical. However, I just remembered the project uses a work email I no longer have, so I should probably update the email shown in the commits for that project, right?
No idea. There's probably not enough information here to decide, and in any case I'm too tired to solve ethical (and maybe legal [see licensing/copyright]) dilemmas ;)
@AndrasDeak Wait. The mailmap only works for the local git repository? So on github for example, my commits would still show my work username and email?
Perhaps there's a fundamental reason for that. For instance .mailmap can vary from commit to commit. When you're looking at a commit in git log you're using the .mailmap from the commit you're on. But when you're looking at a commit on github it might happen that you're not associated with a single branch. At least I think so; I'm not so sure about this. But it's plausible that they have a fundamental reason for not supporting it.
@AndrasDeak Yes, that's it! I also wanted to know which projects are work projects and which are personal projects. So deleting my work credentials would mean in future I probably won't be able to separate work projects from personal projects. GitHub shows the username used to create an account on GitHub, not the username specified by git config --global user.name, and GitHub does not show the committers email.
perhaps the issue is that you're using depth-first-search to discuss in chat
it would probably be more fruitful for you to digest what's been said up to a given point and then reply, rather than always being 30 minutes behind the discussion
