I have a batch script that makes backups from remote camera drives on a private network using wget:
echo off
SETLOCAL ENABLEDELAYEDEXPANSION
FOR %%i in (1 2 3 4 5) DO (
wget64 --http-user admin --http-password instar -r -l inf -nc -e robots=off --directory-prefix=C:/temp/VID_DOWNLOAD -A "*.avi" -R "*999999.avi" http://192.168.0.11%%i/sd/
)
Sometimes (I have not been able to identify why), the wget encounters a problem and must terminate. This generates a dialogue that requires user interaction.
It does not bother me if there is an error, since the script is launched automatically every 5 minutes and wget eventually works fine. The problem is that I manually have to intervene and acknowledge the error.
I don't have much information about the error - it shows up like this:
Would it be possible to get wget to fail silently?

Windows cmd file has the following line
wget "http://ftp.gnu.org/gnu/wget/wget-1.5.3.tar.gz" -P C:\temp >> dld.log
After executing the dld.log file is empty.
What is wrong with output redirection?
It is necessary that the output of wget execution is written to the dld.log file
wget redirects output to stderr mostly to split off from the results data.
So direct answer to to make the current redirect code work is to use 2>&1 to direct sterr stream to stdout as in:
(wget "http://ftp.gnu.org/gnu/wget/wget-1.5.3.tar.gz" -P "C:\temp")>>dld.log 2>&1
However, wget has log functions built in which makes more sense. The switch is --output-file
wget "http://ftp.gnu.org/gnu/wget/wget-1.5.3.tar.gz" -P "C:\temp" --output-file=dld.log
See the wget manual for more info.
I'm trying to use a batch FOR loop inside a psexec. I need to make a script that offers me the possibility to choose the subfolders (I store the items in %list_of_items%) in %local_folder% that are needed to be copied with ncftpput on remote server. I cannot put the entire psexec inside the loop because I dont want to insert every time the password.
The piece of code:
psexec \\remote_server -u DOMAIN\user cmd /c FOR %%i IN "%list_of_items%" DO ("ncftpput -f c:\folders\file_with_creds.cfg -R remote_folder/ %local_folder%/%%i")
Example
I have:
%local_folder%\folder111
%local_folder%\folder222
%local_folder%\folder333
I choose to copy the items folder111 and folder333 so I store them in %list_of_items%. For every item in the list I need to run ncftpput to transfer to remote server the folder but doesnt work....
The error:
"folder111" was unexpected at this time.
cmd exited on remote_server with error code 1.
Can you help me please to find what I'm doing wrong?
Thank you.
I've gotten some help with an earlier part of this batch file, but now I'm having trouble with the final component.
I've tried a few things with no success. I tried changing the CRLF to LF which did nothing. I also tried rephrasing the commands a few ways but I am still not getting anywhere. The following is my main batch file.
#echo on
REM delete deauth command file
SET OutFile="C:\temp\Out2.txt"
IF EXIST "%OutFile%" DEL "%OutFile%"
plink -v -ssh *#x.x.x.x -pw PW -m "c:\temp\WirelessDump.txt" > "C:\temp\output.txt"
setlocal
for /f %%a in (C:\temp\output.txt) do >> "Out2.txt" echo wir cli mac-address %%a deauth forced
REM Use commands in out2 to deauth
plink -v -ssh *#x.x.x.x -pw PW -m "c:\temp\Out2.txt"
pause
Below this sentence is the command found in Out2 which I think is giving the actual trouble. The number of lines varies but they are all this particular command just with differing MACs.
wir cli mac-address xxxx.xxxx.xxxx deauth forced
If Out2 has only a single line it runs fine, no issues. But when there are multiple lines, it fails with an error stating that the Line has an invalid autocommand. It's almost as if it was reading it as one contiguous command. As I mentioned above I changed from CRLF to LF hoping IOS would like it better, but that failed. I've tried adding extra lines between the commands, and I've tried calling the login every time from that file.
I am hoping that there is a way to tailor the commands to pass all lines one at a time to keep this down to a minimum of files.
I had another thought but it is kinda/very clunky. If there was a way to output each of those MAC deauth commands to their own file in a saperate folder (out1, out2, out3), and have the BAT able to run all the randomly generated files in that folder so that each one is a separated plink session.
Let me know if I need to change/add/elaborate on anything. Thanks in advance for anything you guys are willing to help with. I appreciate it.
EDIT: Martin has pointed out what the limitation actually is. It appears to be a limitation on Cisco to accept blocks of commands through SSH. So I still have the same question really, I just need some help figuring a workaround to this issue. I'm thinking the multiple file solution I mentioned above may have some possibility. But I'm too much of a noob to know how to make that work. I'll update if I have any breakthroughs though. Thanks for any contributions!
It's actually a known limitation of Cisco, that it does not support multiple commands in an SSH "exec" channel command.
Quoting section 3.8.3.6 -m: read a remote command or script from a file of PuTTY/Plink manual:
With some servers (particularly Unix systems), you can even put multiple lines in this file and execute more than one command in sequence, or a whole shell script; but this is arguably an abuse, and cannot be expected to work on all servers. In particular, it is known not to work with certain ‘embedded’ servers, such as Cisco routers.
Though you can probably still feed multiple commands to Plink input:
(
echo command 1
echo command 2
echo command 3
echo exit
) | plink -v -ssh user#host -pw password > output.txt
Or you can simply use an input file:
plink -v -ssh user#host -pw password < input.txt > output.txt
Similar question: A way of typing multiple commands in cmd.txt file using PuTTY batch against Cisco
This works without cmd.exe and using files:
function Invoke-PlinkCommandsIOS {
param (
[Parameter(Mandatory=$true)][string] $Host,
[Parameter(Mandatory=$true)][System.Management.Automation.PSCredential] $Credential,
[Parameter(Mandatory=$true)][string] $Commands,
[Switch] $ConnectOnceToAcceptHostKey = $false
)
$PlinkPath="$PSScriptRoot\plink.exe"
$commands | & "$PSScriptRoot\plink.exe" -ssh -2 -l $Credential.GetNetworkCredential().username -pw "$($Credential.GetNetworkCredential().password)" $Host -batch
}
Usage: dont forget your exit's and terminal length 0 or it will hang
PS C:\> $Command = "terminal lenght 0
>> show running-config
>> exit
>> "
>>
PS C:\> Invoke-PlinkCommandsIOS -Host ace-dc1 -Credential $cred -Commands $Command
....
Sounds like your file 'Out2.txt' has only LF at end of line. Simple way to convert that to CRLF is to use MORE command and redirect output to a new file and then use the new file.
more Out2.txt > Out2CRLF.txt
I ran into the same issue when trying to pull the full list of ACLs on an ASA via plink in powershell.
Essentially, due to the abuse issue referenced in the documentation: https://the.earth.li/~sgtatham/putty/0.72/htmldoc/Chapter3.html#using-cmdline-m, I was getting inconsistent results in pulling the ACLs. Sometimes I would get 0, sometimes only 1 or 2, and sometimes I would get all of them. (I personally, had about a 1 in 5 success rate).
As I would occasionally be successful I used a while loop that would catch the unsuccessful attempts and retry. Just be sure to put some timing on the while loop to prevent it from spamming ssh connections too much.
It is not a good solution, but it worked as a last resort.
I rendered 140000 frames to create a movie of them.
However, it starts at 1.png where it would be better if it had started at 000001.png in order to keep the order good when importing it in final cut express.
I used to have a program r-name but that was based on power-pc so it doesn't work anymore.
Also the program was quite shit with even a batch of 300 files for example so i guess it would be better to use the terminal for that.
I have seen examples for renaming but most where for changing the extention for example or change a prefix.
Could someone help me with the right terminal script? I need to finish this project asap, else i would have re-rendered it but it takes 15 hours to do.
Not very efficient, but since you need to run it only once:
for i in `seq 1 140000`; do
mv $i.png `printf %06d $i`.png
done
EDIT: I assumed (maybe wrongly) that you were using Linux. This won't work on Windows.
EDIT: Yes, this should work in Mac OS X. Instead of typing these lines into the prompt, you can save it to a file. Usually, you would save such a file with a name like rename.sh. Then You can run it on the terminal like this:
sh rename.sh
If you are unsure, you can change the mv line into:
echo mv $i.png `printf %06d $i`.png
This will print out on the screen the commands that would be executed. Then if everything looks ok, you change it back to the original and run it again.
If the number of files is different, just replace 140000 with the number of the last file.
for i in *.png
do
name=${i%.png}
[[ $name =~ ^[0-9]+$ ]] && mv $i "$(printf '%06d' $name).png"
done
If you are using Windows
#echo off
setlocal enableDelayedExpansion
for %%F in (*.png) do (
set "name=00000%%~nF"
ren "%%F" "!name:~-6!.png"
)
From what was suggested here, I am trying to pipe the output from sqlcmd to 7zip so that I can save disk space when dumping a 200GB database. I have tried the following:
> sqlcmd -S <DBNAME> -Q "SELECT * FROM ..." | .\7za.exe a -si <FILENAME>
This does not seem to be working even when I leave the system for a whole day. However, the following works:
> sqlcmd -S <DBNAME> -Q "SELECT TOP 100 * FROM ..." | .\7za.exe a -si <FILENAME>
and even this one:
> sqlcmd -S <DBNAME> -Q "SELECT * FROM ..."
When I remove the pipe symbol, I can see the results and can even redirect it to a file within finishes in 7 hours.
I am not sure what is going on with piping large amount of output but what I could understand up until this point is that 7zip seems to be waiting to consume the whole input before it creates an archive file (because I don't really see a file being created to begin with) so I am not sure if it is actually performing on-the-fly compression. So I tried gzip and here's my experience:
> echo "Test" | .\gzip.exe > test.gz
> .\gzip.exe test.gz
gzip: test.gz: not in gzip format
I am not sure I am doing this the right way. Any suggestions?
Oh boy! It was PowerShell all along! I have no idea why this is happening at least with gzip. Gzip kept complaining that the input was not in gzip format. I switched over to the normal command prompt and everything started working.
I did observe this before. Looks like | and > have a slightly different functionality in PowerShell and Command prompt. Not sure what exactly it is but if someone knows about it, please add in here.
