[12:03] oh, many beginners do use IRC [12:03] really? i missed that :( [12:03] who are all these people asking beginners' questions in #ubuntu otherwise ;-) [12:03] I stand corrected. [12:03] estimation of 9milliions ubuntu installed, 1000user in #ubuntu [12:04] I'm just thinking of 98% of my Windows-using friends, stuffing them into the "just-switched-to-Ubuntu" box.

Technical useres of any OS will be more likely to use IRC, but not your every day joe. But I digress OT...

[02:46] relax :) [02:46] i'm relaxin [02:46] before two minute i was in Barcelona [02:46] so the order in rwx is owner group other [02:47] read write execture [02:47] task0: alright lets look at your permission as an example: -rwxr-xr-x [02:47] the first space says whether or not it is a directory (it will have a 'd' there if it is a directory) [02:47] then there are 9 others [02:47] --- --- --- [02:47] the first set of 3 correspond to user permissions [02:48] the middle 3, for group [02:48] user=me?

[02:53] ok, lets continue with permissions [02:53] so with chmod i change permission [02:53] in each group of 3, you can have r for "read", w for "write", and x for "execute" [02:54] so what would this mean: -rwxr-xr-x ?

[03:08] k [03:08] thanks that you ask [03:08] and for how days you remember the permission on linux. [03:09] ubuntu: you mean the numbers? [03:09] aha === tsmithe [n=toby@ubuntu/member/tsmithe] has joined #ubuntu-classroom [03:10] yes? [03:10] yes the numbers [03:11] for how days you remember the permissions. [03:11] ubuntu: ok, so you get 3 numbers xxx . The first number is for the owner/user, the second number is for the group, and the last one is for others [03:11] so lets just look at what one number means [03:11] ubuntu: are you familiar with octal? [03:11] yes i study ccna [03:12] great [03:12] ok lets see then . [03:12] for user you have 3 spaces --- . The first one is for "read", the second for "write", the last for "execute" [03:13] ok i get it [03:13] erm I guess it's more like binary then :) [03:13] so if you have 7 that's 111 in binary [03:13] hex? [03:13] that means read, write, and execute === task0 [n=task0@OL61-36.fibertel.com.ar] has joined #ubuntu-classroom [03:14] 101 would be read, no write, and execute and that's 5 in decimal [03:14] 7 hex is like something like 111 [03:14] 7 hex is 7 [03:14] 7 = 1*2^2 + 1*2^1 + 1*2^0 [03:14] jrib: i'm also here [03:14] hmm ok,go i will after that what was. [03:14] task0: welcome back [03:15] i missed all the class :'( [03:15] ok let me start over, I don't think I was clear [03:15] xchac hun [03:15] hung [03:15] and couldnt restarit [03:15] ok start again [03:15] i had to restar my pc [03:15] xchac? [03:16] ok, we've seen that the permissions can apply to the owner/user, the group, and others and each triplet in --- --- --- represents those permissions === FordCortina_ [n=frank@ACD6BC1E.ipt.aol.com] has joined #ubuntu-classroom [03:16] so we want to just look at one of those. Lets say the user permissions for example === zul [n=chuck@CPE0006258ec6c1-CM000a73655d0e.cpe.net.cable.rogers.com] has joined #ubuntu-classroom [03:16] and we are going to see how we can represent that as a number [03:16] yes [03:17] normally you see it as rwx or r-x, but it could just be 111 and 101 since you can tell that the first spot means read if it is a 1, the second spot means write, and the last spot means execute [03:17] does that make sense? [03:17] no, sory [03:17] k [03:17] 111 = rwx? [03:18] ooo [03:18] ye [03:18] s [03:18] now i get ir [03:18] k, basically you have 3 blanks --- and if the first blank corresponds to "read", the second blank "write", the last one "execute" [03:18] it* [03:18] using letters just makes it easier to read [03:18] so rwx = 111 and rw- = 110 [03:18] exactly [03:18] yes [03:18] ok [03:18] but what about all the 666 777 =? [03:19] one second [03:19] lets stick with just the user part for now [03:19] lets say you have 101 [03:19] ok [03:19] instead of saying 101, you view that as a binary number and convert it to decimal === subnet [n=User@72-161-38-168.dyn.centurytel.net] has joined #ubuntu-classroom [03:19] i'm not good at binary [03:19] so 101 really means 1*2^2 + 0*2^1 + 1*2^0 [03:20] 1 multyplied by 2 elevated to 2? === tsmithe` [n=toby@82-70-109-22.dsl.in-addr.zen.co.uk] has joined #ubuntu-classroom [03:20] the first spot tells you if you have a 2^2 (or 4), the second spot is if you have a 2^1 (or 2), and the last spot is if you have a 2^0 (or 1) [03:21] what is ^ [03:21] so it's 1*4 + 0*2 + 1*1 if you want [03:21] ? [03:21] task0: exponent [03:21] ok [03:21] like 2^3 means 2*2*2 [03:21] yes yes [03:21] ok, so for example what would 011 be? [03:22] 0*4 + 1*2 + 1*1 = 3 [03:22] 0*2 + 1*2 + 1*2 ? [03:22] haha yes [03:22] slow typing [03:22] sory [03:23] ok, so if your user has read and write permissions but no execute, you see that as 110 and just display it as 6 (1*4 + 1*2 + 0*1) [03:23] i still dont get that [03:23] task0: which part? [03:23] all the bonary thing [03:23] bimary [03:24] isn't 1 -- 2 -- 3 [03:24] well you know how when you normally see a number like 587 that really means 5*10^2 + 8*10^1 + 7*10^0? [03:24] so rwx = 7 (1+2+3) [03:24] 1+2+3 is 6 :/ [03:24] lol [03:24] heh [03:25] it's 4, 2, 1 [03:25] read = 4 [03:25] yes [03:25] there [03:25] write = 2 [03:25] ex = 1 [03:25] write, because read means a 1 in the first spot 100, and the first spot there corresponds to 2^2 [03:25] s/write/right [03:25] ugh [03:26] can't i change permission ussing the --- --- --- ? [03:26] yes [03:26] ubuntu asked about the numbers [03:26] yes i asked [03:27] it's ok [03:27] but don't remember when? === tsmithe` [n=toby@82-70-109-22.dsl.in-addr.zen.co.uk] has joined #ubuntu-classroom [03:27] ok, so to finish, if you have read and write for the user, that is 110 which is 6, and then if group and others are just read, then they are each 100 which is 4. So you would represent that as 644 === barsanuphe [n=barsanup@ver78-6-88-166-84-152.fbx.proxad.net] has joined #ubuntu-classroom [03:27] when you have 3 numbers like that, the first number gives you permissions for the user, the second for the group, and the last for others [03:27] so chmod 664 file will do? [03:28] sudo chmod [03:28] becouse is inside system dir's [03:28] task0: that's not what you asked, what permissions do you want group to do? [03:28] task0: wait, what file are you chmodding? chmodding system files can really mess up your system [03:29] ubuntu: does the number thing make sense? [03:29] jrib: i installed enemy territory [03:29] a game [03:29] it isntalled on /usr/local/games/enemy-territory/et [03:29] task0: ah, that's ok then [03:29] you should still be able to run it as your user === tsmithe` [n=toby@82-70-109-22.dsl.in-addr.zen.co.uk] has joined #ubuntu-classroom [03:30] jrib: i want -rwxr-xr-x [03:30] let me [03:30] try [03:30] task0: wait [03:30] task0: so group has r-x, what number is that? [03:30] jrib up-down man,i only see that i forget the binary [03:30] i need to return to open the book in lesson 2 [03:30] 5 [03:30] ? [03:31] task0: right [03:31] so 755 [03:31] :D [03:31] yes! [03:31] wuiii [03:31] now, there is a much easier way to do this so you don't need to learn the numbers [03:31] heh [03:31] i need that [03:31] :D [03:31] you can do stuff like: chmod u=rwx,g=rx,o=rx file [03:32] do i need to give all u, g and o or i can only give one? [03:32] you can give just one [03:32] like chmod u=rwx [03:32] ok [03:32] yep [03:32] in time i think numbers will be faster and easyer [03:33] thank you jrib === tsmithe` [n=toby@82-70-109-22.dsl.in-addr.zen.co.uk] has joined #ubuntu-classroom [03:33] sometimes, chmod can also let you do u+r so it only adds the r permission and doesn't touch other stuff [03:33] with numbers you can't do that [03:33] task0: yw [03:34] jrib: can i ask you another thing? [03:34] task0: sure === subnet is now known as pyk [03:34] can i check if my fstab is correct? === pyk [n=User@72-161-38-168.dyn.centurytel.net] has left #ubuntu-classroom ["Leaving"] [03:34] sure, you can check, I won't stop you :) [03:34] what is fstab?

Avoid ever using sudo [03:36] ooo [03:36] but sudo nano or sudo vim is ok? [03:36] and sudo -i will be rppt [03:36] i mean root [03:36] rppt? [03:37] sudo != root? [03:37] root unlimited access.
