two。 This document is applicable to the windows client operating system xp win7/8/10,windows server-side operating system server 2003 to 2008 and 2012 to 2016.

Forfiles.exe and help

Description:

Select a file (or group of files) and execute a command on that file. This helps batch jobs.

Syntax:

Forfiles / p / d / c

1. See what the use of the three parameters listed is: (simple parsing)

/ p specifies the directory in which to look for files, and the default is the current working directory.

/ d specify a date or number of days to compare whether the last modified date of the file meets the criteria.

/ c the command executed for each file found.

two。 See what the usefulness of the three parameters listed are: (detailed parsing)

/ p: specify the location where to start the search for files, or the current directory by default if not specified.

/ m: the wildcard characters used in file lookup, such as "* .log" in the code, are all log files. Of course, you can also specify all log files that start with manmee, such as "manmee_*.log". If you do not specify this parameter, it defaults to "*. *".

/ d [{+ | -}] [{|}]: specify the last modification time of the file you want to select. "/ d-7" is used above to indicate all files based on the current day and 7 days ago.

Of course, you can also specify a specific time here, such as "/ d-08swap 18max 2009" for all files that are earlier than August 18, 2009. Note that the specified time must be in the format "MM/DD/YYYY".

/ c execute the specified command on all files in double quotes ("). The default is" cmd / c echo @ file ". What is used above is" cmd / c del / f @ path "to delete the specified file. (@ file and @ path here are variables, which will be explained below.

= example illustration =

Example 1. To copy files in the C root directory with a last modification date greater than or equal to July 1, 2007 to the D root directory:

Forfiles / p "c:\" / d "2007-7-1" / c "cmd / c copy @ path d:\"

Example 2.1 Delete files under the backup directory of disk C that were last modified 10 days ago:

Forfiles / p "c:\ backup" / d-10 / c "cmd / c echo deleting @ file... & & del / f @ path"

Example 2.2 automatically delete the test directory of disk D and the last modification date is 7 days before the file

Forfiles / p "d:\ test" / s / m *. * / d-7 / c "cmd / c del @ path"

Example 2.3 Delete the 28-day extension under the current directory to bkf file (based on the current system time)

Forfiles / m * .bkf / d-28 / c "cmd / c del @ file / f"

Syntax parsing of deleted files

Forefiles / p / m-d / c

Forfiles / p contains the full path of the file to be deleted (e.g. F:\ Logfiles) / m * .log-d-7 / c "cmd / c del / f @ path"

Explain the relevant parameters and commands

PATH: represents the full path to the file.

File: indicates the name of the file.

= case action =

1. Delete all empty directories (take deleting the d:\ test directory as an example)

Dir / ad/b/s d:\ test\ | sort / r > d:\ kill.txt

For / f "tokens=*"% I in (d:\ kill.txt) DO rd "% I"

Del d:\ kill.txt

two。 Automatically delete files and directories 7 days ago

{A shortcut to create a bat file is launched, and d:\ test is changed to the directory path you want. Date refers to the date of modification. }

Principle: first delete expired files, and then delete all empty directories, this is a complete deletion process

@ echo off

Forfiles / p "d:\ test" / s / m *. * / d-7 / c "cmd / c del @ path"

Dir / ad/b/s d:\ test\ | sort / r > d:\ kill.txt

For / f "tokens=*"% I in (d:\ kill.txt) DO rd "% I"

Del d:\ kill.txt
