Nice! I think many users are going to like this!

denisfalqueto · 2012-10-23 02:24:30

This is very slick!! you should consider contributing it upstream.

This. Do you plan to do so?

Though after a bit of though, this is more of a translation/shortening of systemctl. Perhaps it should be provided locally by Arch itself. I'd advise a feature request on this (perhaps provide an AUR package for automatic install first, as a proof of concept. For one, should be moved out of .systemd, seems that part will be easy though).

very nice script, love it!

one small bugfix. I had to move the minus sign in the regexp of s_list_services

grep -o "${daemon}[A-Za-z0-9_-/=:]*"

to the end of the expression:

grep -o "${daemon}[A-Za-z0-9_/=:-]*"

because grep was giving me "grep: Invalid range end" errors on tab completion

Nice idea, but maybe some feature requests to the systemd folks could do the job:
- add a third column to systemctl list-unit-files which shows if a service is actually running
- add a switch to choose what to show enabled,disabled,static
- add a switch to hide the .service extension when I type -t service
- add option Hide=always/success to .service files
to hide services completely from the list or only if they have not failed

We can put a link to the AUR-package in the wiki. And as any other AUR-package, if enough people interested we may move it to community.

I may do this at some point in the future, but not now, as I do not use or know anything about zsh.
If someone else would convert the script one time to zsh, I would integrate and maintain it.

denisfalqueto · 2012-10-23 18:46:52

Would you mind putting it on github or some equivalent? I needed a 'isolate' command and had to fall back to systemctl It would be cool to send you patches (I don't have any right now).

I'm not a great developer or bash/script expert, but here's a workaround for zsh

if [ "$SHELL" == "/bin/zsh" ]; then
     compdef s_bashcompletion_start s.start
     compdef s_bashcompletion_stop s.stop
     compdef s_bashcompletion_restart s.restart
     compdef s_bashcompletion_reload s.reload
     compdef s_bashcompletion_enable s.enable
     compdef s_bashcompletion_disable s.disable
     compdef s_bashcompletion_status s.status
     compdef s_bashcompletion_wants s.wants
     compdef s_bashcompletion_log s.log
   else
     complete -F s_bashcompletion_start s.start
     complete -F s_bashcompletion_stop s.stop
     complete -F s_bashcompletion_restart s.restart
     complete -F s_bashcompletion_reload s.reload
     complete -F s_bashcompletion_enable s.enable
     complete -F s_bashcompletion_disable s.disable
     complete -F s_bashcompletion_status s.status
     complete -F s_bashcompletion_wants s.wants
     complete -F s_bashcompletion_log s.log
fi

Works only with s.TAB

Send him a pull request, AJ.

American_Jesus · 2012-10-31 01:48:39

some stuff are not working with that workaround like s.{start,stop,enable,...} daemon.service, i'll try something else
when i got it working properly i make a fork of the repo and send some patches

Delete your fork -- Yaffare hasn't been keeping his github in sync with his releases per his changelog in his original post.

@Yaffare - Since your AUR package pulls from your github, people are not benefiting from the changes you outlined above because the code in your github repo is 8 days old. You gotta push ever change you make. Here is a helpful alias you can add to your shell rc (~/.bashrc I'm guessing) that does this for you. Just be sure you're in the /path/to/local/repo when you call it:

alias gitc="git commit -av ; git push -u origin master"

Could you be a little more specific? What exactly is not working, what error-messages do you get?

Dude, as you can see, the last update here in this post is: moved source to github.
Probably my fault, because I ordered the changes wrong, sorry.
I have not been making any changes to the code since then, because for me, the script is working very well on serveral machines. Also I havent gotten any bug-reports or pull requests, so there was no reason for me to change the code.

You gotta push ever change you make. Here is a helpful alias you can add to your shell rc (~/.bashrc I'm guessing) that does this for you. Just be sure you're in the /path/to/local/repo when you call it:
alias gitc="git commit -av ; git push -u origin master"

But before I can do that I must turn my computer on, is that right? Can you please explain that too.

Right but your DTS on that is only 7 days ago whereas the code in the github is 8 days old. I got the impression that you had some uncommited changes.

Sorry, I'm in a pissy mood. No offence was intended. You clearly have a good handle on scripting. I just wanted to give you a code snipette to help in case you haven't used github before.

start/stop or enable/disable units, not work with that workaround

$ s.stop ntpd.service
::  Stopping ntpd daemon[sudo] password for aj:
sudo: systemctl -q stop ntpd.service: command not found
                                                                     [FAIL]
sudo: systemctl status ntpd.service: command not found

also s.start TAB are not working

btw here's a more clean workaround

if [ "$SHELL" == "/bin/zsh" ]; then
     complt="compdef"
   else
     complt="complete -F"
fi
     $complt s_bashcompletion_start s.start
     $complt s_bashcompletion_stop s.stop
     $complt s_bashcompletion_restart s.restart
     $complt s_bashcompletion_reload s.reload
     $complt s_bashcompletion_enable s.enable
     $complt s_bashcompletion_disable s.disable
     $complt s_bashcompletion_status s.status
     $complt s_bashcompletion_wants s.wants
     $complt s_bashcompletion_log s.log

seems like /usr/bin/ is not in your $PATH when you use sudo. I will change the call to fullpath /usr/bin/systemctl in the future.

Thanks a lot! This is what exactly I want! After moving to systemd I really miss rc.d-style daemon starting/stopping messages. ( https://bbs.archlinux.org/viewtopic.php?pid=1188528 )
