[SHELL] Count lines of code in all files recursively

No commentsApple, Conf, Dev, Ipad, iPhone, Linux Shell, Mac, Mobiledicembre 16th, 2011

Here a unix command line script to count code lines for your project (or something else!).

In this example it counts lines in an Objective-C iOS Application (.h or .m files).

1
2

4
$
$find . \( -name '*.h' -o -name '*.m' \) -print -exec cat {} \; | wc -l
  25812
$

Explanation:

find . \( -name ‘*.h’ -o -name ‘*.m’ \) -print

- list all files endings with .H or .M recursively from current folder (.).

-exec cat {} \;

- while it finds files, exec a cat on current file

wc -l

- count lines of current file and sum it to total.

25812 lines of code! Sounds good!

enjoy!

[ObjectiveC] Build fat static library (device + simulator)

No commentsDev, Ipad, iPhone, Linux Shell, Mac, Mobile, Objective-Caprile 7th, 2011

Hi all,
a promemoria to MERGE Device + Simulator libraries in a “fat” lib with XCODE.

Usage:

1. Create a static lib project
2. Select the Target
3. right-click and “Add … New Build Phase … New Run Script Build Phase”
4. Copy/paste the script below into the box

After that, customize script as you want!

In your BUILD folder you can see Release-Universal folder that contains merged libs with headers file!

[Shell] Argument list too long

No commentsDev, Linux Shellluglio 8th, 2010

As a Linux user, you may have to get the following error:

bash: /bin/rm: Argument list too long

There are a lot of methods to resolve this issue, but I use this stupid and simple one:

Here the code (copy, type vi rmany.sh, paste the code):

#
# rmany.sh
#  - List or delete a lot of files...
#    ...specially in this folder!
#
# (c)apasca
#
#
#!/bin/bash
#
for X in *.$1
do
$2 "$X";
done
#
# FIRST:
#   chmod +x rmany.sh
#   alias rmany='./rmany.sh'
#
# USAGE:
#   rmany [EXTENSION] [COMMAND]
#

You need to make it executable (chmod +x rmany.sh) and optionally add it as alias (alias rmany=’./rmany.sh’).





If you have created an alias you can type on console simply “rmany txt rm” and press enter!

Your input is rmany [EXTENSION] [COMMAND]

[C# / SHELL] Analisi e parsing log

No commentsC#, Linux Shellfebbraio 25th, 2010

Bene,

abbiamo un file di log da 600Mb con 8.791.937 milioni di righe… in formato access.log.gz fatto in questo modo:

1
2
3
[...]
IP.IP.IPP.IPP - - [14/Sep/2009:00:01:22 +0200] "GET /xml.php/getall?cmd=tile&format=jpeg&x=3777&y=5143&z=16&extra=2&ts=256&q=60&rdr=0&sito=test HTTP/1.1" 200 1713 "http://www.ilmiosito.it/call?v=373" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; GTB6)"
[...]

Cosa ci serve? L’url e i suoi parametri? Ok…

Da shell possiamo usare un ZCAT per leggere il file zippato senza aprirlo e magari fare un redirect con meno righe, giusto per fare dei test:

1
$ zcat /tmp/access.log.gz | grep "&x=" | head -2500 > /tmp/small.log

ora abbiamo un file più piccolo…

1
cut -d\" -f2 /tmp/small.log | cut -d\? -f2 | cut -d\  -f1 > CLEAR.log

ora abbiamo un file contenente solo l’url da parsare! Già meglio vero?


Adesso, con C# mettiamo su un parser senza perderci troppo tempo in shell e carichiamo il file!

Può essere comodo usare le liste, in modo da salvare la coppia:

(valore_che_serve),(quante_volte_si_ripete)

1
      var CityList = new Dictionary<string , int>();

e ovviamente salvare o incrementare i valori trovati:

1
2
3
4
       if ( ! CityList.ContainsKey( VALORE ))
              CityList.Add(VALORE, 1);
        else
              CityList[VALORE] = CityList[VALORE] + 1;

così abbiamo per ogni chiave il suo numero di ripetizioni!

Ma poi? Tutto disordinato?
No, no, mettiamo un pò di ordine, magari salvando un file CSV separato da “;” con i valori ordinati dal più ripetuto al memo ripetuto…

1
2
3
4
5
6
7
8
StreamWriter sw = new StreamWriter(@"Z:\alb\ordine.dat");

foreach (KeyValuePair</string><string , int> item in CityList.OrderByDescending(key => key.Value))
{
        sw.WriteLine(item.Key + ";" + item.Value);
        sw.Flush();
}
sw.close();

Ah, per usare le Dictionary e il metodo OrderBy, sono necessarie queste due librerie:

using System.Collections.Generic;
using System.Linq;


Bene, tutto qui!

Adesso abbiamo un file CSV ordinato, con il nostro valore preferito (IP, la città, un url…) e quante volte viene ripetuto!
Per ogni utilizzo!

enjoy.

[SHELL] Unire *.rm e *.camv in AVI

1 CommentLinux Shellluglio 23rd, 2009

Real player usa due file per visualizzare il video in questo formato.
Il file .camv contiene l’xml con le informazioni utili al video e l’altro (rm) contiene l’audio.

real player


Ecco come convertire entrambi, unendoli in un filmato .AVI in linux shell.

   mencoder -audiofile $FOLDER/*.rm $FOLDER/*.camv -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:vpass=2 -oac pcm -o $FOLDER.avi
}

LST=`ls -1 .`
for FOLDER in $LST;
do
    convert
done

in realtà può essere fatto anche su Windows.
E’ scaricabile da sourceforge: http://sourceforge.net/projects/mewig/.
