- Step1: Regular Expression 擷取"小時"資訊並存到t1
perl -ne 'print "$1\n" if /:([0-9][0-9]):/' < access_log > t1
- Step2: 排序t1並存到t2
sort < t1 > t2
- Step3: 刪除重覆列數並統計出現次數, done!
uniq -c < t2
- 一行指令解(不會產生中間暫存檔)
perl -ne 'print "$1\n" if /:([0-9][0-9]):/' < access_log | sort |uniq -c
- 一行指令 + 顯示為"小時:人數"
perl -ne 'print "$1\n" if /:([0-9][0-9]):/' < access_log | sort |uniq -c |perl -ne 'print "$2 $1\n" if /([0-9]+) ([0-9]+)/'
VirtualBox 分享資料夾設定
如何讓 VirtualBox 裡頭的 Ubuntu 存取 Windows 的資料夾? 首先在 VirtualBox 的設定裡頭分享資料夾加入要存取的資料夾, 然後在 Ubuntu 的終端機下執行 sudo mount -t vboxsf temp /mnt/(temp 就是 windows 裡的資料夾名稱), 然後 Ubuntu 下的 mnt 資料夾就會和 temp 互通了。 這應該是最簡的方法,不過有個小缺點,就是每次開機都要執行一次這個指令,不然就不會通了。 PS. 記得要安裝客端額外功能喔!可參考『Ubuntu 在 VirtualBox 下的螢幕解析度調整』這篇文章。
SVN + Trac
- 編輯 vim /etc/apache2/dav_svn.authz, ACCOUNT1 只能讀, ACCOUNT2 可以讀寫, 其它所有都不能進來.(PROJECT_NAME:/, 那個 / 可以是 /trunk => 代表設定誰在 trunk 能做什麼事的意思)
[PROJECT_NAME:/] * = ACCOUNT1 = r ACCOUNT2 = rw
- 增加透過 apache 存取(ci/co)的 使用者帳號/密碼 到 /etc/apache2/dav_svn.passwd
- /usr/bin/htpasswd -c /etc/apache2/dav_svn.passwd ACCOUNT1
- /usr/bin/htpasswd /etc/apache2/dav_svn.passwd ACCOUNT2
- 重新啟動 apache: /etc/init.d/apache2 restart
- 無法啟動apache2, 出現 "DAV not allowed here" 時
- sudo vim /etc/apache2/mods-enabled/dav_svn.conf 修改:
<Location /svn/> DAV svn SVNParentPath /home/svn/repository AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd AuthzSVNAccessFile /etc/apache2/dav_svn.authz Require valid-user </Location>
- sudo vim /etc/apache2/mods-enabled/dav_svn.conf 修改:
- 這樣子就可以做 checkout(co)/commit(ci)/update(up)... 等動作 存取 url 如下:
- svn co http://localhost/svn/PROJECT_NAME
- svn co http://DOMAIN_NAME/svn/PROJECT_NAME
- 同樣於 http://DOMAIN_NAME/svn/PROJECT_NAME/ 應該就會看到 Revision 資訊
