Batch file to download a file from FTP

Question

i want to download the "abcd.txt" file 'n' times with step of 2 mins. Following is the batch (with ftp script in it) file i've created to download a file from FTP.

:DOWNLOAD_AGAIN
@ftp -i -s:"%~f0"&GOTO:DOWNLOAD_AGAIN
open 192.168.4.4
username
password
!:--- FTP commands below here ---
cd /data/
pwd
get abcd.txt
bye

The problem is, 1) Above batch file does not wait for 2 mins, it immediately starts downloading the file again. 2) I dont know how to restrict it to download only 'n' times.

Any help! Thanks!

Answer 1

PING can be used to delay execution for a number of seconds. If specified (-w switch), PING will wait for a number of milliseconds between two pings before giving a time-out.

ie PING 127.0.0.1 -n 6 for a 5 seconds delay. or PING 1.1.1.1 -n 1 -w 60000 >NUL will delay execution of the next command 60 seconds, provided 1.1.1.1 is not a valid IP address

Also you can use TIMEOUT 120 will delay execution of the next command by 120 seconds

And for running batch for n times you can do

FOR /L %i IN (1,1,n) DO (
       //to stuff
 )

The 1,1,n is decoded as:

(start,step,end)

Answer 2

抓住Unix Utilities端口 ，那里有一个有用的sleep程序，它可以让您延迟脚本。

Answer 3

You can use CHOICE 's timeout to wait:

CHOICE /C XY /D X /T 120 > NUL

(offer a prompt choice of X or Y, default to X in 120 seconds & return, hide choice by directing to nul)

Answer 4

In addition to Kaushal's answer, if you're on Vista/7, you may use

TIMEOUT /T 120 /NOBREAK

instead of ping to have the script pause for 2 minutes.
