Handy aliases

[Carles Sentis]

Today at work came up with a new handy alias for bash to just display the directories in a folder

alias lsd='ls -d */'

So, I'd like to know what other handy aliases people have in their .bash_aliases file

@Andrew What does it actually do?

Looks like it SSHes to a box specified on the commandliine, and runs screen followed by bash. Screen is handy because if your session dies, you can reconnect to it when next you SSH in.

See also 'byobu' -- I always install it where I use screen. Gives a kind
of status bar with helpful info, and because that refreshes regularly, I
get timed out a lot less! :)

[Gerard Ryan]

Also (again, not an alias): check out
https://github.com/nojhan/liquidprompt for an adaptive prompt!

Here's also a pretty great prompt for when using Git (I think it's more
useful than what's in the liquidprompt above):
https://github.com/matthewmccullough/dotfiles/blob/master/bash_gitprompt

[Carles Sentis]

I've been using liquidprompt for a while and I quite like it. Handy if you are working in a git folder...

Yep, this alias automatically reconnects to a running screen, or failing
that starts a new screen, or if screen fails (say it isn't installed on
the remote machine) it fires up a plain bash. My bread and butter.

similar time saving, just in case some don't know is bash completion

http://bash-completion.alioth.debian.org/

it will complete well known command arguments.

e.g ssh <TAB> will show a list of known hosts

svn <TAB> will autocomplete svn commands

You can write your own completions also

[gerryk]

While these are all great... TBH, I find that I hop from server to server so frequently that I rarely get round to setting most of this stuff up.

That said... one of the first things I do on a new box is install git and clone my .dotfiles from github.

I'll be creating a little ansible playbook soon for configuring 'nice to have' stuff like this on a server. That way I can just aim it at any server that I use and have things the way I want them :)

There must be an easy way to migrate your home folder across computers. My blog is kinda dead as of late but sometime ago I wrote a post to sync firefox addons across pc's using dropbox, would be nice to have something similar like a script that does it on the background without human interaction. Probably a combination of git and rsync may do the trick from the top of my head. Needs more investigating...

 

[Carles Sentis]

forgot the link of the blog post --> http://myinterestingubuntu.blogspot.ie/2012/02/sync-firefox-addons-using-dropbox.html

[gerryk]

Yeah... that sort of thing is interesting. The whole home directory might be a bridge too far... it would probably enforce version alignment, but stuff like bookmarks, .dotfiles, .vimrc and .[zsh|bash]rc and so forth, definitely.

[gerryk]

Cheers for that.

That's the thing that makes it interesting or a bit complicated the fact that you can't just synch the whole home folder but a selected items like .dotfiles and also perhaps some of the .dotfolders with application specific settings...

I guess ideally would be something that runs on startup and logging off to run a rsync and git commands every time. Issue could be for merge conflicts while running git.

[gerryk]

I read the blog post. Interesting, but I'm sure that you can't just copy in XPI like that. Certainly not signed ones anyhow.
Also... What's with the click and paste a link? It's not bloody windows.

I think a custom solution, using rsync as you described, sounds like a good one to investigate.

[Carles Sentis]

ha ha!! thanks for the feedback. Syncing firefox addons with dropbox works very well. I've been using it for a good while now. At least it works with the addons i have.

I will definitely look into the automation of the saving part of the home folder once I have some time. There's a little bug eating me away right now...

This is a git alias but I thought it suited the thread.

To view the changes from a commit:

• git config --global alias.changed 'show --pretty="format:" (to add it to .gitconfig)
  

and then:

• git changed bAda55 (to view commit changes)
• git changed --name-only bAda55 (to view the files changes)
• git changed --name-only bAda55..ff0021 (lists files modified between those commits)
• etc...
  

[Carles Sentis]

A couple of aliases for git I use which I found sometime ago in stackoverflow

• git config --global alias.lg1 'log --graph --format=format:"%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)" --abbrev-commit --date=relative'
• git config --global alias.lg2 'log --graph --format=format:"%C(bold blue)%h%C(reset) - %C(bold cyan)%aD%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n"" %C(white)%s%C(reset) %C(dim white)- %an%C(reset)" --abbrev-commit'

and then to use:

• git lg1
• git lg2

This is another alias for bash to prettify json's from terminal:

• alias json='python -mjson.tool'

and the to use I can just do:

• $ echo '{"name":"myname"}' | json
  

[gerryk]

Oh, I like those json ones. Gonna steal them.

Another thing one might like to do is customise your bash prompt....you can add the output of any command to it

One time I had it show the current svn branch name

http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/index.html

[Carles Sentis]

@Antoin I use liquid prompt for this which Gerard already mentioned --> https://github.com/nojhan/liquidprompt

[Antóin Óg Ó Cuinneagáin]

sorry didn't see that....just downloaded now...looks cool

[Nicola Di Marzo]

Hi,

Try this one:

/sbin/modinfo $(/sbin/lsmod|cut -d" " -f1)|grep -E '(description|filename)'

I call it "everymod", it lists description and filename of every module loaded by the system.

Pretty similar, but this it lists every man page/description in PATH:

for x in ${PATH//:/ }; do cd $x; whatis *; done | sort

Hope all you're well,
cheers
Nicola

Hi Nikola,

Thanks for those, they look like they could be useful sometimes!

Here's one that you probably shouldn't have an alias for (or even use):

:(){ :|:& };:

from http://en.wikipedia.org/wiki/Fork_bomb :D

Could really mess with someone's head if you aliased that to ls or
something common like that!

[Nicola Di Marzo]

:D ops. I usually run 'em as scripts or commands.
But here we're actually talkin' about aliases, maybe i'm little bit OT
Hope you will find 'em useful anyway.
Cheers
