我照wenlien大大所說把script作了測試
#!/bin/tcsh
/tools/bin/pgp -e sss mykey << EOF
y
EOF
以及
#!/bin/tcsh
echo y | /tools/bin/pgp -e sss mykey
執行後還是會停住要我輸入(y/N)

引用但是，如果DB換帳號密碼，那php裡面的設定就要一定改～
所以，可以把邏輯寫成Stored Procedure，然後用MySQL的event來執行。
上述的問題就可以解決!
1, 請問php 那部份需要改 ?
2, 如何可以寫成Stored Procedure ?
謝謝!

$mysql_pass = '';
$mysql_db = 'quotadb'; // Not the DB to check, but the db with the quota table
$mysql_table = 'quota';就是在建 table 時設好每個欄位大小
不然就用下面的方法

大大您好just give the temp table an alias:
不好意思，他這次是顯示以下訊息，是否有解，感謝
MySQL 傳回： 說明文件
#1248 - Every derived table must have its own alias
感謝你的回覆與解答 雖然是"暴力法" 也是可能可以解決問題awk, sed在做完資料修改後, 會將結果顯示到標準輸出. ( 我不知道是否有辦法可以直接修改檔案 )
我原先想用AWK 或 SED 來做 功力不夠所以卡在這裡
不過這其實更加簡單 又很直覺 謝謝

SELECT ip, sum( bytes ) bytes(

MySQL 傳回： 說明文件

兩位大大好
有辦法把byte欄位加起來嗎
因為有時候today和week的ip會重覆,如下
10.1.1.6分別在today和week出現
today
ip bytes
10.1.1.1 60
10.1.1.2 70
10.1.1.3 80
10.1.1.6 30
week
ip bytes
10.1.1.4 90
10.1.1.5 50
10.1.1.6 40
合併成一張table後會把ip相同部份的byte欄位給加起來
如下
ip bytes
10.1.1.1 60
s10.1.1.2 70
10.1.1.3 80
10.1.1.4 90
10.1.1.5 50
10.1.1.6 70
如果單單只使用union和union all似乎無法做到
想請問若是要這樣語法該如何下,感謝
各位大大好
小弟使用mysql
有以下2 table
today
ip bytes
10.1.1.1 60
10.1.1.2 70
10.1.1.3 80
week
ip bytes
10.1.1.4 90
10.1.1.5 50
合併成一張table如下
ip bytes
10.1.1.1 60
10.1.1.2 70
10.1.1.3 80
10.1.1.4 90
10.1.1.5 50
這個用right joind和left join好像都不對
但是mysql 似乎不支援full join
想請問一下這個語法要怎麼下,感謝
各位大大們你好:
我在裝完Ubuntu 10.04 之後,
發現有一個process (polkitd) 一直在吃掉我的記憶後,
最終他占用很大的記憶體, 讓我的系統慢到不行.
我曾試著把他kill掉, 但是他還是被系統重新啟動.
所以, 想問:
1. 請問這樣的情形是daemon的bug嗎?
2. 這個daemon很重要嗎? 可以把他關掉嗎?
3. 請問該如何關掉他?
感謝.

各位先進 我想要讀取一個TEXT檔 的第一行 其中一個欄位作為SHELL SCRIPT處理的變數來源
但是同時也必須將第一行從原來的檔案刪除 如此原來的第二行遞補 做為下一次SCRIPT的來源
可是我想不出來要怎麼做比較方便
TEXT 檔案格式(file-list.txt):
aaa.0529.xyz
bbb.0530.abc
ccc.0531.opq
第一次SCRIPT執行時 讀取第一行 aaa.0528.xyz 摘取0528 做一些處理
但是同時也需要將 aaa.0528.xyz 從原檔案中移除 (也不要空行 否則製造下次讀取麻煩)
最主要也是因為SCRIPT 會產生一個新的檔名 append 到 file-list.txt 的最後一行
變成為(file-list.txt):
bbb.0530.abc
ccc.0531.opq
ddd.0601.rst
有先進可以指點一下使用BASH 如何做出類似SCRIP? 感謝
