linux之tmpwatch命令

標籤：

系統使用時間長後會產生臨時檔案（/tmp下），需要清理。但清理的時候不推薦使用rm -rf。這樣有時會引起程式的僵死。

tmpwatch的說明：

[[email protected] ~]# tmpwatchtmpwatch 2.9.16 - (C) 1997-2009 Red Hat, Inc. All rights reserved.This program may be freely redistributed under the terms of theGNU General Public License version 2.tmpwatch [-u|-m|-c] [-MUadfqtvx] [--verbose] [--force] [--all] [--nodirs] [--nosymlinks] [--test] [--quiet] [--atime|--mtime|--ctime] [--dirmtime] [--exclude <path>] [--exclude-user <user>] <hours-untouched> <dirs>

 

簡介 :
tmpwatch 工具從指定的目錄中遞迴地搜尋，並刪除在指定時間段內沒有被訪問的檔案。tmpwatch 一般被用來清掃那些用來臨時駐留檔案的目錄(譬如，/tmp)tmpwatch 忽略符號連結，它不會切換檔案系統，而且只刪除空目錄和常規檔案。

語 法：tmpwatch [-afqv][--test][超期時間][目錄...] 

補充說明：執行tmpwatch指令可刪除不必要的暫存檔案，您可以設定檔案超期時間，單位以小時計算。 

參數： 
-a或--all 　刪除任何類型的檔案。 
-f或--force 　強制移除檔案或目錄，其效果類似rm指令的"-f"參數。 
-q或--quiet 　不顯示指令執行過程。 
-v或--verbose 　詳細顯示指令執行過程。 
-test 　僅作測試，並不真的刪除檔案或目錄

執行個體： sudo /usr/sbin/tmpwatch -afv 4 /tmp （清除/tmp下四小時以內沒有使用的檔案，並將結果輸出）。

執行個體如下：
