WikiwideI don't understand backtick quotes. What do they do in ash script? Makes parsing wget output quite difficult.07:18
Wikiwide15:29:50 (20.69 KB/s) - `filepath' saved [43121]07:34
WikiwideFor example,  test="$(echo "15:29:50 (20.69 KB/s) - `filepath' saved [43121]")" line doesn't work - Terminal switches to > mode07:59
*** trumee has quit IRC08:43
brolin_empeyWikiwide: If I recall correctly, what you refer to as backtick quotes are some ASCII approximation anachronism popular with the FSF/rms.  I say anachronism because modern practice is to use Unicode separate left and right single or double quotation marks, i.e., ‘single’ and “double”.08:56
*** trumee has joined #maemo09:00
brolin_empeyIn your example/use case, it appears that the shell is expecting the ` to be used for command substitution?09:01
brolin_empeyI guess a possible workaround is to use tr(1) to replace the ` with ' .09:02
brolin_empeyOr maybe the program that uses ` in its output can somehow be told at runtime to use a different quoting style?09:03
WikiwideI might have worked around this by using grep -o \`.*\' , And then % and # bash string editors to remove suffix and prefix. But it's still a rough ride.09:07
brolin_empeyVajb: You may say “difficult” instead of “hard”.09:10
brolin_empeyCatButts: ISP is also In-System Programming.09:12

brolin_empeyCatButts: KCalc can be used to convert between binary, octal, decimal, and hexadecimal.09:25
*** Wikiwide has quit IRC09:29
brolin_empeyI wonder if the D-Link DUB-E100 hardware version D1 still uses the same vendor and device identifiers as the hardware version C1.  My patch to the Maemo power kernel that I submitted in 2013 was to add support for the hardware version C1 that was current in 2013.  Now I have two of the hardware version D1 at work but stopped using the N900 in 2014.  When I am back at work, I should check the identifiers used by the hardware version D1.09:36
CatButtsDec 29 10:17:49 <freemangordon> why don't you just use wpa_passphrase?09:58
CatButtsin place of wpa_cli?09:58
CatButtsoh yeah, it outputs to stdout10:05
CatButtsI'd have to pipe it to a file10:06
CatButtsbutt you see...10:06
CatButtsI can't find my angled brackets :P10:06
CatButtsso wpa_cli it is!10:06

CatButtsdificult are the times11:41
CatButtshard is the surface to smack head against when times are dificult11:41
CatButtsdd if=/dev/mmcblk1 of=./mybackup.img11:53
CatButtsthis is taking unusually long11:53
CatButtsam I doing something naughty?11:54
CatButtstaking moreso, than say....11:54
CatButtsdd if=./mybackup.img of=/dev/mmcblk111:54
CatButts2gb SD card11:55
CatButtseh, with a bit of luck, it's not filling up all of 32gb MyDocs :P11:57
CatButts(ext2 formated)11:57
CatButtshmmmm, ext2....11:57
CatButtsso that's why it's taking long11:58
CatButtsI once made the mistake of using ext3 as backup drive for very large files(tens of GB)11:59
CatButtswriting to it would be stupendously slow11:59
CatButtsthen I nuked the fucker and made it ext411:59
CatButtsproblem solved11:59

KotCzarnywikiwide: i would advise you to learn about shell scripting exploits12:02
WikiwideThank you :-)12:02
WikiwideI am just absolutely tired. Exhausted.12:03
KotCzarnyand the fact that you have troubles with parsing output suggest it might be insecure12:03
KotCzarnyas for backtics it's treated in bash as `run this command in new subshell`12:03
WikiwideInsecure, as in, random things injected into script?12:04
KotCzarnyand '> ' means it was waiting for closing backtick12:04
KotCzarnyand executed on your system12:04
KotCzarnywhole shell scripting is tricky12:05
WikiwideWell, it's not like website can easily put anything into script. It's just, wget output has stderr and stdout in the same stream, and certificate warning get mixed up with filenames.12:05
KotCzarnybut you plan on making it into some package in repos for others?12:06
WikiwideTry wget , and see what wget says.12:06
WikiwideNot package yet. Just a script, for starters.12:06
* CatButts starts to regret making MyDocs into ext212:07
KotCzarnybecause while your private script would just fail, used by others might be treated as attack target12:07
Wikiwidehildon-mime-summon is somebody's package in extras-devel which needs some help. Its source package has both source and binary, while its binary has neither.12:07
WikiwideAnd, its binary doesn't exit upon having done its task; it just gets stuck in waiting for a Ctrl-C or some killall.12:08
KotCzarnyadd & ?12:09
WikiwideBut overall, it works as intended, opening /any/file with proper mime handler.12:09
WikiwideIt gets stuck in background. Neat but not sufficient. There is no reason for it to not exit.12:11
KotCzarnymaybe it waits for browser close12:14
KotCzarnyor needs to call destination app with '&'12:14

WikiwideHildon-mime-summon being closed and destination app being closed have absolutely no correlation. Feel free to test, binary executable is inside source package and source code, too, of course; .C13:04
