Find files that are created more than 7 days and delete them using bash

admin — Wed, 18 Jan 2012 23:31:29 +0000

Here we will use the find -mtime and xargs commands

Complete script:

find '/home/user/data/' -name '*.txt' -mtime +7 | xargs rm

Explanation:
find -mtime displays files made based on given number of days

find '/home/user/data/' -name '*.txt' -mtime +7

xargs captures the result of a previous command and pass it as an argument for another function

find '/home/user/data/' -name '*.txt' -mtime +7 | xargs rm

The result of the find command is passed to another function rm which then removes the files

Subversion svn auto deploy project on commit

admin — Thu, 14 Apr 2011 10:19:25 +0000

Automate the deploy of your project on svn commit, this require you have access to your svn server

On your server got to your repo folder
/usr/local/svn/my_repo
———————————————————————–
then go to hooks folder
/usr/local/svn/my_repo/hooks
———————————————————————–
then copy the post-commit.tpl to post-commit
cp post-commit.tpl post-commit

the post-commit file is a file called by subversion after every commit, basically its a bash script
———————————————————————–
chmod the post-commit file
chmod +x post-commit
———————————————————————–
Now lets edit the post-commit file.
Lets say your project dev directory resides on the same server, the post-commit file has content so we erase them all and add this

#!bin/usr/bash
cd /home/dev_website
svn up .

what the bash does is change directory to the /home/dev_website then execute the svn update command
———————————————————————————————————————————————–

and were done, next time there is no need to log in to the server just to svn update of your dev website.
