Remove files from git repo through .gitignore

If you add a folder to .gitignore you can then update your repo status removing the newly ignored files w/ one command:

git rm --cached `git ls-files -i -X .gitignore`

It'll remove cached files from the ignored ones, reading from .gitignore. Note that files will be removed just from the repo, not from your filesystem.

From git help ls-files

-i, --ignored Show only ignored files in the output. When showing files in the index, print only those matched by an exclude pattern. When showing "other" files, show only those matched by an exclude pattern. -X <file>, --exclude-from=<file> Read exclude patterns from <file>; 1 per line.

ciao posso avere un tuo cv professionale? Grazie

Ciao angeloradici,

mi dispiace, ma non è mia consuetudine lasciare il mio curriculum e non ne avrei nemmeno uno pronto non essendo in cerca di impiego.

Se ti interessa sapere qualcosa di specifico su di me o sulle mie competenze puoi senz'altro chiedermelo qui.

Scusa per il tempo impiegato a risponderti.

Buona giornata :)

MySql ruby-gem without MySQL

Trying

$ gem install mysql2

w/o having MySQL installed locally? You'll miss mysql.h. Resolve with

$ sudo apt-get install libmysqlclient-dev

Test strings against regex in bash

Hey, talking about nowdays bash (GNU bash, version 4.2.45(1)-release (x86_64-pc-linux-gnu)), let's look at this:

$ str='0000.cacca' $ [[ "$str" =~ ^[[:digit:]]{4}\.cacca$ ]] && echo "yes" || echo "no" $ yes

Yum yum

#Regex #regular expressions #bash #test #scripting

Now tell me for what the fucking reason python-pyxattr should have to depend on libjs-sphinxdoc! Why Debian? Why? And why on jacascript-common????

I'd just want to install rdiff-backup :'''''(

Breeder

Hey ya! Just released this little sweet and funny piece of code: https://github.com/welaika/breeder.

From the README:

Let it bring up your local virtual hosts

Breeder is crafted for developers, who want to set up a local LAMPP virtual host with a single command in your terminal.

Cheers

WordPress 3.5.2-it_IT broken installation

For me is official. I've tested it in many way and I have to say that WordPress 3.5.2 in its italian localization is broken.

Upgrades from prevoiuos version works flawlessly, but fresh install won't. The cause, in my experience, is that this commit merged in 3.5 WP branch is not present in italian localization.

Applying the patch manually will work, however.

Anyone experiencing the same problem?

#wordpress #wp #3.5.2 #italian #broken

Explode-like editing in SublimeText2

Quick and dirty. Context: split this one-line array into multiple lines

$strings = array('DISALLOW_FILE_EDIT', 'EMPTY_TRASH_DAYS', 'WP_ALLOW_REPAIR', 'WP_POST_REVISIONS', 'DISABLE_WP_CRON', 'WP_CONTENT_DIR', 'WP_CONTENT_URL', 'UPLOADS', 'WP_PLUGIN_URL', 'WP_PLUGIN_DIR');

cursor inside the brackets

CTRL+SHIFT+M

CTRL+F

digit a comma

ALT+ENTER

press ENTER

Almost done. You'll be in multi-line edit mode, so do whatever you want now! :)

Lovely, isn't it?

Looking for bad guys. The Perl counterpart

Ehy! I've thrown out on github a search&scan perl engine based on regular expression collections. The aim is to implement a passive security scanner against some attacks (webshells, htaccess hacks, etc.) fast enough to go through hundreds of thousands files and my goal is to have such a scanner configurable just pushing into it new regexes while I discover theme on the web, inside webshells code, on our hosting servers (bad stuff guys!).

Really early code, but we are testing massively. Someone could be interested at the little project and should go to https://github.com/pioneerskies/lfbg.pl.

When it will be more stable I'll migrate the code to weLaika's github repository.

Renaming power-up with rename

Just a few posts ago I was talking about a little trick using mv almost useful in scripting.

But you have to keep in mind that rename exists. I'll talk with examples, just while I'm using it:

pioneerskies@pis-laptop:~/dev/scripts/bunctionsh/helpers (git:master) $ ls chweb colorize_feedback git-prompt lampp randpass pioneerskies@pis-laptop:~/dev/scripts/bunctionsh/helpers (git:master) $ rename 's/^(.*)$/$1_off/' * pioneerskies@pis-laptop:~/dev/scripts/bunctionsh/helpers (git: master △ ) $ ls chweb_off colorize_feedback_off git-prompt_off lampp_off randpass_off

So:

1st arg: a perl regex! FTW! Not only with s(ubstitution) command, but also with p, y, d, like sed; this will do the transformation on selected files

2nd arg: is the selector, like in bash. So .jpg, *, [0-9] are all accepted

So hawt

#sed #rename #mv #bash #regex #pre

(MT)(GS)(BK): our definitive (MT) Grid-Service backup solution

We use (MT)(GS) and we find it great for a certain range of our needs. But I love backups, so I've searched for a good backup solution for (GS); probably the only serious one is http://gsbackup.org, which I find so damn cool, but does not answer to my needs.

Backup for my devs @welaika and for our clients must have:

external location

cron friendly...

...and so non-interactive

a bit secure

use as little as possible of the production server's resources

...well...restorable. I mean RESTORABLE!

Ok now sorry if I'm going OT, but I mean RESTORABLE! A compressed tarball with a fucking myriad of files for an amount of 10GB, is not restorable! Ok? Come back to us now.

Remember that I'm a sysadmin, not a dev. So what have I done to do a backup as I like? Well I've just managed to compile rdiff-backup on (MT)'s Grid-Service. Voilà!

All our centralized backup system is based on rdiff-backup, so after I installed it on GS, I've added them to our backup system and it works like a charm. Woha!

Some complexities

Due to the jungle of symlinks and to the fact that rdiff-backup doesn't follow them I have tricked a bit to get the right configuration.

Firstly the path

I've got the right path doing

$ ssh user@gs-server pwd

that is the one that will work, because is the one absolute path that rdiff-backup will find connecting to the server via SSH.

The include path

If you want to use a globbing file list or --exclude --include options, remember that you'll have to use the full path to write them

/nfs/cxx/hxx/mnt/122087/domains /nfs/cxx/hxx/mnt/122087/mydir

How?

I've written a stupid script that works. You can clone or just read it from here: https://gist.github.com/pioneerskies/5085751 Basic instruction there...but is just the case of a

bash (BK).sh

Conclusions

Have fun guys. Tell me if in trouble. And if you are interested in the script that we use to manage all the backups wrapping rdiff-backup, let me know; at the moment it works, but the code is awful and expecting a deep refactor, so I'm not going to shout it at the world just now. ;)

recompile with -fPIC lib/mylib.o: could not read symbols: Bad value

I'm a sysadmin but I'm not a compiling expert at all. I faced up the error as reported in the title of this article and I felt confused; when the magic of compiling source code does not work it's like the nyancat starts floating in your head. I know that feel bros.

So I'm just here to share a good as the hell howto from the great gentoo community. Go and read it!

#compile #source #make #cflags #cxxflags #gcc #-fPIC

Even if [ ! -z "$PS1" ]

Remember: there are a lot of possibilities that in your .bashrc there's a line at the top similar to this one

# If not running interactively, don't do anything [ -z "$PS1" ] && return

so if you want to export a goddamn ENV VAR even if in a non-interactive shell, put it first of that line.

#memorandum #bash #terminal #sysadmin #bashrc

mv along the scripting way

No, this isn’t fucking philosophy, but just a _memorandum_ of a trick using *mv* command inside script -t, —target-directory=DIRECTORY move all SOURCE arguments into DIRECTORY In this way you can pass successives args as files to be moved and so use it with *find*, in a *loop*, where you want! Remember and njoy!

#mv #bash #scripting
