Linux temporary file cleanup

Article Title: Linux temporary file cleanup. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

A temporary file (under/tmp) is generated after the system has been used for a long time and needs to be cleared. However, rm-rf is not recommended for cleanup. In this way, the program may be frozen.

We recommend that you use the tmpwatch command for cleanup. Tmpwatch is described as follows:

Name: tmpwatch

Version: 2.8.4

Release No.: 5

GROUP: System Environment/basic source package: tmpwatch-2.8.4-5.src.rpm

Size: 13273 license type: GPL

Abstract: A tool used to delete a file based on the time when the file is accessed.

Introduction:

The tmpwatch tool recursively searches for and deletes a specified directory.

Files not accessed within the specified period. Tmpwatch average

Used to clean directories (for example,/tmp) used to temporarily resident files)

Tmpwatch ignores symbolic links and does not switch to the file system.

Only empty directories and regular files are deleted.

Syntax: tmpwatch [-afqv] [-- test] [expiration time] [directory...]

Note: Execute the tmpwatch command to delete unnecessary temporary files. You can set the file expiration time, measured in hours.

Parameters:

-A or -- all delete any types of files.

-F or -- force forcibly deletes a file or directory. The effect is similar to the "-f" parameter of the rm command.

-Q or -- quiet does not display the instruction execution process.

-V or -- verbose displays the instruction execution process in detail.

-Test is only used for testing and does not really delete files or directories.

Example: sudo/usr/sbin/tmpwatch-afv 3/tmp (clear files not used in the next three hours of/tmp and output the results ).

Effect:

[Yyc @ localhost ~] $ Sudo/usr/sbin/tmpwatch-afv 3/tmp
