On my current position, I had to update my project with Subversion every morning. It took half an hour every day ; some other guys prefered to update only once a week or twice a month… But they accepted to spend half a day for merges etc.
Yet, I found a way to make this update automatically, thanks to a planned task in Windows XP.

The command that is launched is
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:update /path:"C:\the\path\of\my\project" /notempfile /closeonend

Thanks to another planned task, I rebuild the complete project with Maven. And on breakfast I find my project up-to-date with all jars compiled and available.

Il suffit de lancer la commande suivante, en passant eventuellement en parametre le fichier source (sinon c’est l’entree standard qui sera utilisee):

tr "àçéèêëîïôöùüÂÇÉÈÊËÎÏÔÖÙÜ" "aceeeeiioouuACEEEEIIOOUU"

Use one of the three following commands:

• tr abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ
• tr a-z A-Z
• tr '[:lower:]' '[:upper:]'

Abstract: you have to remove duplicate lines in one file. For instance, you have a file:

foo1

foo2

foo2

Solution: use this command:

uniq myFile.txt

You’ll get:

foo1

foo2

Case: you have to sort the content of a file in Unix.

Solution

sort -d sourceFile > destinationFile

Abstract: we need to retrieve all the files in current folder (and its sub-folders) of which size is greater than 10 Mo

Use:

find . -type f -size +10000 -print

Abstract: we need the max of two dates

Abstract: we would like to add the SVN-keyword $Id$ to all SQL files.

• go to SVN config folder (mainly $HOME/Subversion/config)
• search for line:

[auto-props]

• just below, add the following line:

 *.sql = svn:keywords=Id
