msys git single file history

In Git BASH
gitk -- path/to/file &

Or right click on file
Then click "Git History"

BTW...
Not only file, files in folders also do.

net snmp 尋找 mib tree

先看 net snmp
把mib檔設定一下 然後載入mib檔

找名字含有ssl的snmp oid
snmptranslate -TB '.*ssl.*'

從 http://www.net-snmp.org/wiki/index.php/TUT:snmptranslate 看來的...

html encode/decode using javascript

1. String.prototype.encodeHTML = function() { var d=document.createElement("div");(d.textContent)?(d.textContent=this):d.innerText=this;return d.innerHTML };
2. String.prototype.decodeHTML = function() { var d=document.createElement("div");d.innerHTML=this;return d.innerText||d.textContent };

net snmp

net-snmp download

安裝至預設路徑C:\netsnmp


設定 C:\netsnmp\usr\etc\snmp\snmp.conf
document -> C:\netsnmp\usr\docs\Net-SNMP.chm

#放mib的地方
mibdirs C:/netsnmp/usr/share/snmp/mibs-XXXX
persistentDir C:/netsnmp/usr/snmp/persist
tempFilePattern C:/netsnmp/usr/temp/snmpdXXXXXX

#載入所有的mib
mibs all

#預設版本 snmpv2c
defVersion 2c

#預設Community
defCommunity private


然後就可以用cmd來下指令了...

P.S.
記得要加環境變數 ;C:\netsnmp\usr\bin 在PATH後面...


snmp走走...
snmpwalk 192.168.1.1 system

從頭走到尾...
snmpwalk 192.168.1.1 .1

snmp翻譯成樹狀...
snmptranslate -IR -Tp system

Git get diff file list and diff content from some branch

1. BRANCH_NAME='dev'
2. SOURCE_DIR='/home/me/src'
3. EXPORT_TO='/home/me/out'
4.  
5. cd $SOURCE_DIR
6. git diff --name-only $BRANCH_NAME > $EXPORT_TO/changes.txt
7. git diff $BRANCH_NAME > $EXPORT_TO/changes.diff
8.  

Unix like shell - find_keywords

1. #!/bin/sh
2. if [ "xx$2" != "xx" ] && [ -e $2 ]; then
3.     echo finding $1 in $2
4.     if [ "xx$WINDIR" != "xx" ]; then
5.         grep -lr $1 $2 | sed 's~/~\\~g' | sed 's~^\\\(\w\)\\~\U\1:\\~g'
6.     else
7.         grep -lr $1 $2
8.     fi
9. else
10.     echo first param must be search string
11.     echo second param must be full path
12. fi

CodeBlocks 中文化

下載mo檔:
codeblocks translation page
www.badongo.com - Click Here to Download codeblocks zh_TW
www.u-file.net - Click Here to Download codeblocks zh_TW

然後建一個目錄 C:\Program Files\CodeBlocks\share\CodeBlocks\locale\zh_TW
其中 C:\Program Files\CodeBlocks 是安裝路徑
然後把mo檔放到裏面去

Settings -> Environment -> View -> Internationalization
勾起來 -> 選 Chinese
然後重開CodeBlocks

搞定...

BTW...中文化以後, syntex highlight好像消失了...
所以還是把勾勾拿掉好了....sigh.....

Compare a Copy of a Project

Usage:

compare-projects /home/me/project/ /home/me/old/project/ | grep -v OK > /home/me/compare_result 2>&1

Source: compare-projects

1. #!/usr/bin/sh
2.  
3. #
4. # settings
5. #
6.  
7. md5=~/bin/md5files
8.  
9. #
10. # inputs
11. # src: main project
12. # dst: another project
13. #
14.  
15. src=$1
16. dst=$2
17.  
18. #
19. # limit file size smaller than 1024k (pass to find)
20. # md5 all files, and then replace the path to destination
21. # finally compare the md5 "use md5sum -c"
22. #
23.  
24. $md5 $src -size -1024k | sed "s!${src}!${dst}!g" | md5sum -c 2>&1

Get All Files Recursively and Get MD5

1. #!/usr/bin/sh
2.  
3. #
4. # find all files recursively, and enum them to get md5sum
5. # args: pass all to find
6. #
7.  
8. for f in $(find $@ -type f);
9. do
10.     md5sum $f
11. done

使用javascript產生guid

參考來源: http://note19.com/2007/05/27/javascript-guid-generator/

javascript

1. function guid() {
2.     function S4() {
3.         return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);
4.     }
5.     return (S4() + S4() + "-" + S4() + "-" + S4() + "-" + S4() + "-" + S4() + S4() + S4());
6. }

html javascript 小時鐘 digit clock

就像這樣:

html javascript

1. <span id="__current_datetime__">
2. <script type="text/javascript">
3.     (function () {
4.         var target = "__current_datetime__";
5.         var padLeft = function(str) {
6.             str = "00" + str;
7.             return str.substring(str.length-2)
8.         };
9.         var getCurrentDateTime = function() {
10.             var d = new Date();
11.             return d.getFullYear() + "&#24180;"
12.                 + padLeft(d.getMonth()+1) + "&#26376;"
13.                 + padLeft(d.getDate()) + "&#26085; "
14.                 + padLeft(d.getHours()) + ":"
15.                 + padLeft(d.getMinutes()) + ":"
16.                 + padLeft(d.getSeconds());
17.         };
18.         var updateCurrentDateTime = function(id) {
19.             document.getElementById(id).innerHTML = getCurrentDateTime();
20.         };
21.         updateCurrentDateTime(target);
22.         setInterval(function() {
23.             updateCurrentDateTime(target);
24.         }, 99);
25.     }) ()
26. </script></span>
