what do I need to append to ls if i want to list only the filenames of all the files in the specified file system that are unwritable? i wish i had information retention of above dementia levels i read about this before it's specified by xx-r-x or something like that file permissions right?

@JeffSchaller the "I still have so much to learn" feeling for me is literally nauseating, and on the maple forum ive found threads where people have told me to change to linux spanning almost a decade before i actually did, and knowing more now about why they were saying that, yeah feeling pretty stupid tbh

@AdamL To find all regular files in or below the current directory that you don't have write permissions for: find . -type f ! -perm -u=w

Stephen Kitt

or -writable (is that a GNU extension?)

Kusalananda

That's a GNU extension, yes.

... but useful.

So, find . -type f ! -writable, with GNU find. This would take things like ACLs into account too.

@StephenKitt I assume the - here means "not"?

No, sorry, that would be the !, I expect.

Stephen Kitt

@FaheemMitha - introduces all the actions etc. in find, not is indeed !

Faheem Mitha

@StephenKitt Right. Sorry for the mistake.

Stephen Kitt

@FaheemMitha no need to apologise!

Adam L

@Kusalananda thankyou so much for that, I'm just hoping that seeing where they are in relation to everything else will help me understand things and why they are non writable, started with reading the man page for readline, and in reading that /etc/inputrc is unwritable,has me wonder how many which ways i could ruin my OS like i did with my Ubuntu, which didnt really matter but I would be pretty devastated if the same happened with my Debian

Stephen Kitt

@AdamL use ~/.inputrc, that way if you really mess things up you can still log in as root and fix things

sure that was the plan but I have never mucked around with environmental variables before its just nerves, like when I first started to learn reg ex i thought i was awesome after 24 hrs and literally wiped an entire OS from this laptop in a single rm command, thankfully it was an Ubuntu and didnt matter but how easily it can happen is the lesson i took from it

it's just more reading in order to read what im reading im going to be stuck here for the rest of the night

8-bit clean

8-bit clean describes a computer system that correctly handles 8-bit character encodings, such as the ISO 8859 series and the UTF-8 encoding of Unicode. == History == Up to the early 1990s, many programs and data transmission channels assumed that all characters would be represented as numbers between 0 and 127 (7 bits); for example, the ASCII standard used only 7 bits per character, avoiding an 8-bit representation in order to save on data transmission costs. On computers and data links using 8-bit bytes this left the top bit of each byte free for use as a parity, flag bit, or meta data control...

if i dont getting good at number theory is an epic waste of my time i dont want to be math com 20 yrs latter as an elderly disheveled green trophy junkie

i need to exit online communication as my maturity is exponentially declinig

11:15 AM

@AdamL The rm command and the shell does not use regular expressions, so I can imagine that using a regular expression as a shell pattern could possibly cause havoc under some circumstances.

Oh dear. I seem to have a text processing issue.

I wonder if regexes can "help". I put help in quotes for obvious reasons.

Ooh, finally. The TeX Live Debian update I've been waiting for.

Jeff Schaller

1:56 PM

@Kusalananda although you could be forgiven for thinking that zsh supported regular expressions, between cN,M and (#s) and (#e)

2:12 PM

@FaheemMitha Are you trying to have two issues?

1 hour later…

Faheem Mitha

3:19 PM

@jesse_b Maybe. Perhaps. Perchance.

Faheem Mitha

3:39 PM

Does anyone know why libfreetype-dev replaced libfreetype6-dev?

Stephen Kitt

@FaheemMitha because -dev packages aren’t supposed to include the soname in their name, unless they’re designed for parallel installation

Faheem Mitha

@StephenKitt So why was there one there, then?

Is 6 the soname then?

Stephen Kitt

@FaheemMitha because when Freetype 2 was initially packaged, it was co-installable with Freetype 1; now that Freetype 1 is gone, libfreetype-dev is unambiguous

@FaheemMitha yes, libfreetype.so.6

Faheem Mitha

@StephenKitt Oh. And no Freetype 3?

@StephenKitt Ok, thank you.

Stephen Kitt

@FaheemMitha no for the time being ;-)

jesse_b

3:48 PM

I understand some of the words you all are using

Faheem Mitha

@StephenKitt Ok. The reason I asked is that I'm trying to backport TeX Live from unstable.

And there's a build dependency on libfreetype-dev.

So I changed it to libfreetype6-dev. Fingers crossed.

Stephen Kitt

@FaheemMitha yes, that should work for stable

Faheem Mitha

4:05 PM

@StephenKitt Thanks for the moral support. :-)

There's an awful lot of C code in the world. I wonder who wrote it.

@StephenKitt Seems to have built successfully. Onward!

Stephen Kitt

@FaheemMitha I’m expecting an upload to debian-backports :-P

Faheem Mitha

@StephenKitt I've never got a response from there.

Stephen Kitt

4:21 PM

@FaheemMitha yes, you need to go through a DD (and ideally, be a DM)

Jeff Schaller

4:56 PM

@StephenKitt you forgot the polite cough -- Stephen Kitt, Debian Developer

i never had any success with signing up with the debian forum. something deep down says i do deserve it for some reason. How can i return the number of characters used to store the current value of a variable in a shell script, and then the number of bits needed for each? is there a straight forward one line way to do this? like i am just interested in retriving on char at a time which is easy using var1= echo ${var0:0:$m} in a loop that ends if var1=var0 and returns the value of m that

condition is met for, this will be the total number of chars used for the value of var0, but i dont know how to find the number of bits for individual chars

one* char at a time sorry

and obviously ive only described the script and am sucking at actually pulling that off

sorry just wanted to mention that with my Debian installs, I have occasionally run it in recovery mode (by choice) and looking at the output during boot, it seems to be a good thing to do, definitely claims to have done tasks like finding missing essential drivers and installing them, i don't know maybe it happens on a normal boot but no output is shown

i obviously have no clue if it is beneficial i just notice a lot of output and it is different every tme

maple should have a package for maple code to bash scripts that would definitely save this brain hurt\

if not ill just keep saying nice things about Canada

what

what SE community will help me do that btw

im not exactly very knowledge about canada all i know comes from south park with cant bone well
