F5 執行 .pl 異常 出現 /usr/bin/perl^M: bad interpreter: No such file or directory

F5 執行 .pl  異常/bin/sh^M: bad interpreter: No such file or directory

在Linux中執行.sh腳本
異常/bin/sh^M: bad interpreter: No such file or directory

分析：
這是不同系統編碼格式引起的：在windows系統中編輯的.sh文件可能有不可見字符，所以在Linux系統下執行會報以上異常信息。

解決：

1）在windows下轉換：
利用一些編輯器如UltraEdit或EditPlus等工具先將腳本編碼轉換，再放到Linux中執行。
轉換方式如下（UltraEdit）：File-->Conversions-->DOS->UNIX即可

2）也可在Linux中轉換：
首先要確保文件有可執行權限
chmod a+x filename

 

然後修改文件格式
vi filename

利用如下命令查看文件格式
:set ff 或 :set fileformat

可以看到如下信息
fileformat=dos 或 fileformat=unix

利用如下命令修改文件格式
:set ff=unix 或 :set fileformat=unix

:wq (存檔退出)

最後再執行文件
./filename

將Terminal 的session儲存log

Save all of your Terminal activity to a file 
May 11, '12 07:30:00AM • Contributed by: chrisgerke

I use Terminal everyday, and I find it a good idea to log everything I you. It makes it much easier to undo your mistakes when you know what those mistakes were. Here's how I do this: 

Open Terminal's preferences. 

Go to Settings, then Shell. You can choose here to run a command at startup. You could create a simple log of your session using the following:

/usr/bin/script ~/Desktop/Terminal.log

This will log everything you do and append it to the log file. 

I like to keep my history so instead I wrote this small script that archives previous sessions by renaming the file with a date/time string. I then set Terminal.app to run at startup the following command:

~/Desktop/logger.sh

Here's the script:

#!/bin/bash 

# logger.sh 

# Log everything you do in Terminal. 

#* Formatted date & time string. 

FORMATTED_DATE=`/bin/date "+%Y-%m-%d%H%M%S"` 

#* Archive the previous file 

/bin/cp -f ~/Desktop/Terminal.log{,.$FORMATTED_DATE.txt} 

#* Begin a new one 

/usr/bin/script ~/Desktop/Terminal.log

 

[kirkmc adds: This is a good idea. I don't use Terminal a lot, but I find that I sometimes need to remember a command I ran in the past which is no longer in my history. 

Also, this is similar to something I do with texts I write. I do most of my writing in BBEdit, and I have a number of "scratch" files which I change every year. For example, I have one file for most of what I write, another just for Mac OS X Hints, and another for a specific client I write for. I archive these files at the end of the year, and create new ones. If I ever need to go back to these files to look for something I can do so. I don't bother to enter dates - which I could do easily enough with a TypeIt4Me shortcut - but if I'm looking for something I'll generally know what text to search for.]

備份自己 FreeBSD system configuration(系統檔案)使用 tar 指令.

備份自己 FreeBSD system configuration(系統檔案).

I set up a simple script to create a configuration backups of my FreeBSD box and I thought I would share it. Note that this script will only back up the /etc and /usr/local/etc directories and weighs in at just under 1MB per backup.

First create a backup script as we can't execute our complex command directly in cron.  You may want to customize the exclude options to your licking, the two listed exclusions are the rather large gconf defaults, witch is not needed, and the working files for transmission.

[root@FB91lab02 /home]#vi /usr/local/sbin/backup-config

貼上下面的內容
bash -c 'tar -Pczf /root/freebsd-cfg-`date "+%Y-%m-%d"`.tgz --exclude={etc/gconf,usr/local/etc/transmission/home/{resume,torrents,Downloads,blocklists}} /etc/ /usr/local/etc/'

Now make it executable.

chmod +x /usr/local/sbin/backup-config

Now add the job to cron and set it to run weekly as root.

修改 cron job

[root@FB91lab02 /home]#vi /etc/crontab

每周備份

# Backup the entire server configuration once a week.
0 1 * * 0 root backup-config 2>/dev/null

tar備份打包時，預設為相對路徑；而排除匹配式預設也是全路徑匹配的所以，在打包時，會提示：“tar: Removing leading `/’ from member names”除非你使用-P參數或特定的參數指定。 
它是tar命令為了避免不必要的錯誤而做的限制。如果使用者在壓縮檔時使用了絕對路徑，那麼tar會自動的剝離掉第一個‘/’。 
例如，你想備份/etc的內容： 
$tar -zcvf etc.gz /etc 
生成了一個壓縮包，那麼在解壓這個壓縮包的時候，內容會被寫入到/etc這個目錄，可能潛在的造成風險。 
經過tar剝離第一個’/’後，解壓時壓縮包的內容會被釋放到目前的目錄，即：./etc。 
如果非要使用絕對路徑，那麼請加-P參數(解壓縮時也需要加上這個參數)。 
如果想蓋面解壓縮目錄，請加-C參數。

今天設定 netapp 進階模式 順便紀錄一下

         them only when directed to do so by NetApp

下如過要離開的話很簡單 只要執行一下 這個指令

STEP1:【框架概念】

1. 框架的設定是跟其他的HTML標籤太一樣。他的用法是在一個網頁上擺上數個網頁。我的首頁就是一個例子。
   現在你假裝想像一個frame是你整個螢幕的大小, 而 frame 的標籤就是把整個螢幕分成許多部分。
2. 接下來, 讓我來看右邊這張圖。 
   ??右邊那個 index.html 是什麼啊? 在右邊這張圖, 我們用 index.html 這個網頁把其他 a.html, b.html, 和 c.html 三個網頁呈現在index.html這網頁上。簡單來說, 就是我們需要多個網頁來作一個有數個框架的網頁。
3. 大概知道框架的概念了吧? 我們要幾個框架, 就需要多少個 HTML 網頁就是了。接下來是語法講解...。

NetApp cifs 搬遷 (舊有CIFS檔案系統升級到N2220 )

最近接到一個 NAS升級案 發現 robocopy 無法將系統權限套用

可以使用fastcopy 是看看 這樣可以減少很多檔案權限設定的問題

強烈建議 搬遷檔案要使用 administrator 比較不會有問題
