| 00:15.22 | Digit | is there a way to get "apt search" output only 1 line per result? or a way to get "apt-cache search" to show version numbers (still 1 line per result)? |
| 00:15.38 | Digit | i mean, without elaborate awking/sedditing/etc |
| 00:17.45 | gnarface | just pipe the output to less |
| 00:17.51 | gnarface | apt-cache search . |less |
| 00:18.32 | gnarface | then you can use the basic keyboard navigation at least |
| 00:18.51 | Digit | uhh, nope. doesnt do what i'm looking for at all. worsens. |
| 00:19.14 | gnarface | i know it doesn't do what you asked for, but it was the closest you're gonna get without learning anything |
| 00:19.41 | gnarface | fyi "apt-cache search" does support some regexp syntax though, more than just basic wildcards |
| 00:20.05 | Digit | e.g. search result would show "packagename packageversion" |
| 00:20.21 | gnarface | you want "apt-cache show [package name]" |
| 00:20.28 | gnarface | the version will be in the output |
| 00:21.05 | Digit | i'll probably just end up sedditing my way to 1 line output. |
| 00:21.20 | gnarface | combining search and show in the way you suggest, would as far as i know require "elaborate awking/sedditing/etc" |
| 00:21.44 | gnarface | maybe try aptitude? some people like it more |
| 00:22.14 | gnarface | it might include versions in the output, i'm not sure |
| 00:22.39 | Digit | yeah, gnarface that's again far from what i want. XD your suggestions are adding lines, not removing them. seems a simple requirement i would have thought would be more popularly sought. search output with just "packagename packageversion" |
| 00:22.57 | gnarface | oh you can search with the package version |
| 00:23.07 | gnarface | it just isn't shown in the output of search |
| 00:23.17 | Digit | needed for inclusion in scripts. idk aptitude well... it's all tui, no? |
| 00:23.22 | gnarface | but the search regexp itself does actually search against the whole output of all the package headers and such too |
| 00:23.42 | gnarface | so you can definitely search by package and version if you know the package header format and regexp |
| 00:24.29 | gnarface | for most packages, typically they don't store more than one version in the repos for an extended period of time though, so there's a limit to the usefulness of that |
| 00:29.21 | gnarface | "dpkg -l" will list versions of packages too, but only if they're already installed |
| 00:29.42 | Digit | nods |
| 00:30.54 | gnarface | hmmm. ack, i may be wrong that the Version tag is even searched by apt-cache search.... |
| 00:32.06 | Jjp137 | Digit, try: dpkg-query --show package |
| 00:32.27 | Jjp137 | you can use --showformat to control the output; refer to the man page, as always :) |
| 00:32.51 | gnarface | as for aptitude, i don't know if there's a way to call it non-interactively. i just assumed there would be but it would not be the default. |
| 00:34.18 | Digit | hrm. dpkg-query --show teeworlds (the package i'm testing on) gives: dpkg-query: no packages found matching teeworlds. that another case of only installed packages? |
| 00:34.55 | gnarface | i don't actually know for sure but i assume so |
| 00:35.01 | gnarface | dpkg is typically for direct package manipulation |
| 00:35.14 | gnarface | apt* is what adds repository support |
| 00:35.28 | Digit | coulda also been complications from the complexity of my system. |
| 00:35.49 | Jjp137 | oh nah I didn't consider that part, oops |
| 00:37.28 | gnarface | i'm guessing there will have to be two calls here, one to "apt-cache search" to get a list of package names, and another to "apt-cache show", "apt-cache showpkg", or "apt-cache showsrc" |
| 00:37.45 | gnarface | (to grep for versions) |
| 00:38.55 | gnarface | more fields than just the package name are searched by "apt-cache search" but "Version: " doesn't appear to be one of them. i'm having trouble isolating exactly which by testing |
| 00:40.44 | gnarface | maybe "Provides: " is searched |
| 00:40.51 | gnarface | in addition to package name and description |
| 00:41.18 | gnarface | at some point i must have caught a version number in there and thought "Version: " was included, sorry |
| 00:42.06 | gnarface | i'm not even sure Description is searched actually now with amprolla |
| 00:42.20 | gnarface | i recall someone complaining about that before and now i'm seeing it |
| 00:42.30 | Jjp137 | the short description (the one-liner) would be |
| 00:42.45 | Jjp137 | the long description...uh yea it disappears if the package came from Debian |
| 00:43.16 | Digit | elaborated: apt-cache show bc | cut -d" " -f2 | head -n 2 | paste -d " " - - |
| 00:43.18 | Digit | :D |
| 00:43.56 | Digit | tho, that still needs work for more elaborate multi result output. |
| 00:44.41 | gnarface | apt-cache show bc|grep ^Version |
| 00:44.42 | gnarface | ? |
| 00:45.24 | gnarface | (grep has similar regexp syntax to apt-cache search) |
| 00:45.27 | Digit | mm, yeah, i should grep wiser |
| 00:46.16 | gnarface | i think you can trust the field names to all be labeled like "Fieldname: " |
| 00:46.25 | gnarface | i don't know if you can trust them to always be in the same order |
| 00:46.40 | gnarface | or even to all be present every time |
| 00:47.24 | gnarface | but they should always start on their own line |
| 00:47.36 | gnarface | so you should be able to grep for "^Fieldname: " |

| 00:55.14 | Xenguy | Digit: Reading quickly, but this sounds like a grep exercise, and I'm still not clear on what your actual requirement is, besides '1 line', of 'something' |
| 00:56.04 | Xenguy | Oh, gnarface has it sorted, so ignore my comment |
| 00:56.46 | Digit | package search output of "packagename package version". yeah. well, had hoped i could skip the text manipulation exersize i'm going through. now i'm going through it, it doesnt hurt so much. n_n |

| 00:58.41 | Xenguy | = ) |
| 00:59.30 | Digit | s/package version/packageversion/ meh, whatever. u get what i mean. like "bc 1.06.95-9+b3" or "teeworlds 0.6.5+dfsg-1~deb9u1", but want it (and am working on) getting it so it works for multiple results n partial package names in the search. |
| 00:59.46 | Xenguy | Should be: apt-cache show grep |grep -i version |
| 01:00.04 | Digit | Xenguy: that doesnt have the package name. we're past that. |
| 01:00.16 | Xenguy | picky picky |
| 01:00.20 | Digit | hehe |
| 01:00.29 | Xenguy | ; -) |
| 01:01.29 | Digit | apt-cache show bc | cut -d" " -f2 | head -n 2 | paste -d " " - - ...&... apt-cache show teeworlds | egrep '^Version|^Package' | paste -d " " - - | sed 's/Package: //g' | sed 's/Version: //g' ... are two early versions inadequate for multiple results. gonna make one from "apt search" output that should do the job. ... might take a break first. |
| 01:01.43 | Xenguy | weeeeeeee, pipe city! |
| 01:01.46 | Digit | n_n |
| 01:02.03 | Xenguy | Time to play some golf |
| 01:02.23 | Xenguy | But whatever works, right? |
| 01:06.04 | Digit | or from "apt-cache search -f" output |
| 01:06.17 | Jjp137 | do note that apt, as opposed to related commands like apt-get or apt-cache, is more of an end-user tool and can change behavior between versions (see the bottom of apt(8) for details) |
| 01:06.29 | Jjp137 | so I would just use apt-cache for this probably |
| 01:06.56 | Digit | yep yep yep. *nods* :) |
| 01:07.30 | Xenguy | Jjp137: I've been trying apt out here and there, and it seems to work quite nicely... |
| 01:07.47 | Jjp137 | yea for interactive use it's fine |
| 01:07.56 | Xenguy | I also read that it is more or less compatible/interchangeable with apt-get, so that is a bonus IMHO |
| 01:08.01 | Jjp137 | but for scripts, prefer apt-get, apt-cache, etc. |
| 01:08.05 | Xenguy | Jjp137: Yeah, they say don't script it |
| 01:08.09 | Xenguy | Exactly |
| 01:09.45 | Digit | ooh! my prior version, all i need to do to make it work is s/apt-cache show/apt-cache search -f/. :D pleasant. |
| 01:10.40 | Xenguy | Golf! |
| 01:10.42 | Xenguy | Well done |
| 01:12.10 | Digit | n_n thnx for putting up with me. thnx for the suggestions n help, all. :) |
| 01:12.23 | Xenguy | I'm tempted to engage the exercise myself, but, on 2nd thought, nah ; -) |
| 01:12.30 | Xenguy | Glad to have you here |
| 01:16.50 | Digit | well, in my script, apt-cache search -f "$argv" | egrep '^Version|^Package' | paste -d " " - - | sed 's/Package: //g' | sed 's/Version: //g' is not as simple&pretty as just apt-cache search "$argv", but it's nice to get consistent output with name and version, without bloating output to multi-line per package. :) nnnnnice. :) |
| 01:17.34 | Digit | (that $argv's fish, change to whatever that is for your bash, i forget... $1 or something?) |
| 01:18.18 | Xenguy | cheats: apt-cache show grep |grep Package && apt-cache show grep |grep Version |
| 01:20.02 | Digit | tries that with teeworlds package, and tries it with s/show/search -f/, sticks to what he has |
| 01:24.25 | Xenguy | $ apt-cache show teeworlds |grep Package && apt-cache show grep |grep Version |
| 01:24.26 | Xenguy | Package: teeworlds |
| 01:24.42 | Xenguy | ^^ Scratch that |
| 01:24.50 | Xenguy | $ apt-cache show teeworlds |grep Package && apt-cache show grep |grep Version |
| 01:24.50 | Xenguy | Package: teeworlds |
| 01:24.50 | Xenguy | Version: 2.27-2 |
| 01:25.20 | Xenguy | Then I'd just use a text editor macro to massage the output |
| 01:25.32 | Xenguy | But that's a quick and dirty approach |
| 01:25.55 | Xenguy | If you've got a better solution, then go for it of course |
| 01:31.02 | Digit | yeah, already pasted it in here a couple times. ;D |
| 01:34.22 | Xenguy | Well that's what I meant of course |
| 01:34.49 | Xenguy | "There's more than one way to skin a..." Er, n/m |
| 01:35.09 | Digit | more than one way to egrep ;D |
