I know how to silently install an msi by using /qn. I also know how to download something just by using the command start http://www.example.com/file.exe. But how do I put these two together in a batch file?! I want to download it, then install it, all silently.
Try start /w URL to see if it will modally wait. If not, download wget for Windows and use it with that start /w option:
start /w "wget -c http://example..."
start /w "file /qn"
if not errorlevel 1 echo Success!
There may be gotchas, but this should push you in the right direction.

WSL2 clock goes out of sync after resuming from sleep/hibernate.
A workaround was shared on GitHub sudo hwclock -s to resync clock in WSL, but you have to do this every time you resume from sleep/hibernate.
UPDATE: THIS BUG IS FIXED, just check for updates! See the Clock Sync fix
In case anyone finds this via search and doesn't notice that there is actually a solution listed in the question, you can fix WSL clock drift via.
sudo hwclock -s
If you just need to do it occasionally, this is a fine solution. If you need to do it more frequently, consider #piouson's solution
Update
The fix is now in WSL2 Linux kernel 5.10.16.3 and newer! Note you may need to install WSL2 from the Windows Store to get the latest kernel version per this thread with Craig from Microsoft.
Older Answer
sudo hwclock -s gets you kind of there, but for some reason doesn't get the exact time - I often find it's a minute or so in the future!
sudo ntpdate pool.ntp.org should get you the correct time.
But this is all because of a bug in the Linux kernel which should be included in a Windows update at some point...
There are a number of hacks referenced in the the GitHub issue which can work around this, mostly, but not always, in my experience...
just restart wsl, it works fine for me
wsl --shutdown
then
wsl
in PowerShell
UPDATE: as mentioned by drkvogel, the Clock Sync fix was released in WSL2 kernel version 5.10.16.3
OBSOLETE
At time of writing, this GitHub Issue was open for the bug.
The workaround I chose for my situation (single distro in WSL2) is to use Windows Task Scheduler to run hwclock in WSL whenever Windows resyncs hardware clock.
Windows: Open PowerShell as Administrator
schtasks /create /tn WSLClockSync /tr "wsl.exe sudo hwclock -s" /sc onevent /ec system /mo "*[System[Provider[#Name='Microsoft-Windows-Kernel-General'] and (EventID=1)]]"
Set-ScheduledTask WSLClockSync -Settings (New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries)
WSL2: Run sudo visudo and add hwclock to sudoers to skip password prompt
# bottom of my file looks like this
...
...
#includedir /etc/sudoers.d
<username> ALL=(ALL) NOPASSWD:/usr/sbin/hwclock, /usr/bin/apt update, /usr/bin/apt upgrade
Results
See image for how to get Event XPath from Windows Event filtering. Use as provided to let task scheduler auto-display scheduled triggers.
Use cron to schedule sudo hwclock -s
As others said before sudo hwclock -s syncs the clock,
but you will need to do this after every sleep/hibernate.
Solution is to add an hourly cron task to sync the clock.
Open crontab with sudo (must open with sudo since the command uses sudo):
sudo crontab -e
and add this code with a new line after the task (it's a cron requirement):
PATH=/sbin:/bin:/usr/bin
#hourly hwclock -s
You must either set PATH since root-cron do not has it or use absolute paths e.g. /usr/sbin/hwclock.
cron troubleshooting:
To verify cron is working you may add a dummy task (don't forget to add a new line):
* * * * * date > /tmp/log.txt
If no file is created, verify cron is working: pgrep cron.
If no PID shows, start cron with: sudo service cron start.
To learn cron timing method: cron timing generator
Necro'ing this: As of May 2022, this issue persists to a degree.
There are two components.
First, Windows time sync needs to be decent to start with. It's not, out of the box, on machines that aren't domain-joined.
Change w32time to start automatically. In Administrator cmd, but not PowerShell, sc triggerinfo w32time start/networkon stop/networkoff. Verify with sc qtriggerinfo w32time. To get into cmd that way, you can start Admin PowerShell and then just type cmd.
Make a few changes in regedit.
In Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32time\Config, set MaxPollInterval to hex c, decimal 12.
Check Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32time\Parameters\NtpServer. If it ends in 0x9 you are done. If it ends in 0x1 you need to adjust SpecialPollInterval in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32time\TimeProviders\NtpClient to read 3600
Reboot, then from Powershell run w32tm /query /status /verbose to verify that w32time service did start. If it didn't, check triggers again. If all else fails, set it to Automatic Delayed startup
Second, WSL2 needs to actually stay in sync. MS will likely release another kernel fix. In the meantime a scheduled task can bring it back into sync periodically:
schtasks /Create /TN WSL2TimeSync /TR "wsl -u root hwclock -s" /SC ONEVENT /EC System /MO "*[System[Provider[#Name='Microsoft-Windows-Kernel-Power'] and (EventID=107 or EventID=507) or Provider[#Name='Microsoft-Windows-Kernel-General'] and (EventID=1)]]" /F
This GitHub Issue was closed
You can also run the below command in Powershell Terminal so sync it.
wsl.exe sudo hwclock -s
You can manually update the WSL2 kernel to 5.10.16 by following the method in this comment: #5650 (comment). I have fixed the issue by this method.
I've added this to Windows Task Scheduler, set to run every 12 hours:
wsl.exe -d ubuntu -u root -- ntpdate time.windows.com
To install ntpdate:
sudo apt install ntpdate
For me this issue seems to be happening when the system goes to sleep. So I have registered a bash command to call whenever, it goes out of sync. I did it by adding a function.sh file and sourced it in ~/.bashrc.
function.sh:
YELLOW='\033[0;33m'
NC='\033[0m'
TIME_SERVER=ntp.ubuntu.com
# Sync wsl time
sync_date () {
echo -e "${RED}sudo ntpdate $TIME_SERVER ${NC}"
echo
sudo ntpdate $TIME_SERVER
}
~/.bashrc:
source ~/Linux/funtions.sh
Note that I have added a bit of color and some customizations (TIME_SERVER: [windows time server is other option]).
You can sync the time using sync_date command in cli.
I have installed several times the package GI-1.9.4-preview20140611.exe on my Windows 8. When I try to open the git bash command window, the window opens, but it is empty, no showing the usual welcome message and the git prompt.
I have tried changing the command for the sh.exe file, which usually has the format
"sh.exe --login -i" into just "sh.exe". The shell opens then, the PS1 variable shows only the sh.exe file name and version, nothing more. Is there something wrong with my installation?
Thanks!
Your installation is fine.
The git executable(sh.exe) for Command Line Tool is a script that in order to work will be based on the your windows Command Prompt (cmd.exe)
You will need the following string to refer to Git correctly as an executable:
C:\Windows\SysWOW64\cmd.exe /c ""C:\Program Files (x86)\Git\bin\sh.exe" --login -i"
Or you can always 'right-click' and SELECT 'Git Bash Here' or 'Git GUI Here'
I found a way to uninstall IE 10 using a batch file which below and it works great like it's suppose to. It uninstalls and restarts the computer after about a minute.
FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-10..mum /c "cmd /c echo Uninstalling package #fname && start /w pkgmgr /up:#fname /norestart /quiet"
shutdown -r
But I wanted to take this further and Hide IE 10 from windows updates which will prevent windows to install this update actually in the future and to do that, Microsoft provides an executable file which you can download from here
http://www.microsoft.com/en-us/download/details.aspx?id=36512 After extracting this executable, you get 3 files, IE10_Blocker.adm, IE_blocker.cmd and IE10_BlockerHelp.htm and Microsoft instructions are "In the Command Prompt, goto the folder where you have extracted these 3 files and type “ie9_blocker.cmd /B” and hit Enter to set the blocker on the machine."
I decided to make one batch file for all this so right now I got this far.
FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-10..mum /c "cmd /c echo Uninstalling package #fname && start /w pkgmgr /up:#fname /norestart /quiet"
mkdir “C:\IE10”
copy /Y \file01p\Users\test\public\IE Update blocker\IE10*.* “C:\IE10”
start /d C:IE10\IE10_Blocker.cmd /b
shutdown -r
mkdir “C:\IE10” This command is suppose to create the directory called IE10 on C drive
copy /Y \file01p\Users\test\public\IE Update blocker\IE10*.* “C:\IE10” This command will copy those executable from the network public folders to their C:\IE10 which I just created in the previous step.
This script doesn't work. Only up to uninstalling IE 10 it works but it doesn't create the directory and so it doesn't copy the files from the network. How can do this?
Thanks
Thanks
Try running your batch as administrator.
in an administrator : command prompt it makes the directory without issue.
also, it could be that you do not have access to make the directory on C:
you could try locating it elsewhere that you are sure you have write access.
First steps in FreeBSD: trying to run my installation script. Fast help needed:
# ls
configure
# file configure
configure: Bourne-Again shell script text executable
# ./configure
./configure: Command not found
# configure
configure: Command not found
What is wrong, how can I execute this script?
Do you have bash installed? If not use FreeBSD Ports to install it. Use where bash to find out.
Use the force Luke :)
# pkg_add -r bash
May it be, that your's configure script doesn't have appropriate executions rights. Try to cast:
chmod 777 configure
If it works, fix it to
chmod 764 configure
configure scripts are ultra portable shell scripts. There is no need for bash here. The problem is somewhere else.
What's the first line in the configure script? Maybe a CR/LF snuck in, which is a common cause for a totally misleading error message saying that the script was not found, when it was the interpreter that was not found.
Please try /bin/sh ./configure
Install the bash package using
pkg add bash
or
make -C /usr/ports/shells/bash install clean
By default FreeBSD comes with tcsh and a POSIX compatible FreeBSD sh
On older FreeBSD systems you will need to do
rehash
before you can run it.
First line of this script (#!/usr/bin/bash, i suppose) should be changed to #!/usr/local/bin/bash.
And of course, you should have shells/bash port installed.
I installed Mono on my iMac last night and I immidiately had a change of heart! I don't think Mono is ready for prime time.
The Mono website says to run the following script to uninstall:
#!/bin/sh -x
#This script removes Mono from an OS X System. It must be run as root
rm -r /Library/Frameworks/Mono.framework
rm -r /Library/Receipts/MonoFramework-SVN.pkg
cd /usr/bin
for i in `ls -al | grep Mono | awk '{print $9}'`; do
rm ${i}
done
Has anyone had to uninstall Mono? Was it as straight forward as running the above script or do I have to do more? How messy was it? Any pointers are appreciated.
The above script simply deletes everything related to Mono on your system -- and since the developers wrote it, I'm sure they didn't miss anything :) Unlike some other operating systems made by software companies that rhyme with "Macrosoft", uninstalling software in OS X is as simple as deleting the files, 99% of the time.. no registry or anything like that.
So, long story short, yes, that script is probably the only thing you need to do.
Year 2017 answer for those, like myself, looking at SE first and official docs later (FYI I know the question was for OS Leopard). Run these commands in the terminal:
sudo rm -rf /Library/Frameworks/Mono.framework
sudo pkgutil --forget com.xamarin.mono-MDK.pkg
sudo rm -rf /etc/paths.d/mono-commands
Seems the uninstall script has been slightly modified as today (2011-07-12):
#!/bin/sh -x
#This script removes Mono from an OS X System. It must be run as root
rm -r /Library/Frameworks/Mono.framework
rm -r /Library/Receipts/MonoFramework-*
for dir in /usr/bin /usr/share/man/man1 /usr/share/man/man3 /usr/share/man/man5; do
(cd ${dir};
for i in `ls -al | grep /Library/Frameworks/Mono.framework/ | awk '{print $9}'`; do
rm ${i}
done);
done
You can find the current version here.
By the way: it's the same exact thing that runs the uninstaller mentioned by joev (although as jochem noted it is not located in the /Library/Receipts, it must be found in the installation package=.
To expand on feelingsofwhite.com's answer, the Mono installer for Mac OS puts the uninstall script in the /Library/Receipts directory, not in the installer image as it says in the Notes.rtf file. The Receipts directory is what the Mac OS Installer.app uses to keep track of which packages were responsible for installing which files. Usually, a list of these is kept in a .bom ("Bill of Materials") file, which can be explored with the lsbom command.
In the case of Mono, they also add a whole bunch of links from your /usr/bin and man directories. Their uninstall scripts finds these and removes them. Since the uninstall script lives in a place the uninstaller deletes, you should probably copy the uninstall script somewhere else before running it:
cd
cp /Library/Receipts/MonoFramework-2.4_7.macos10.novell.universal.pkg/Contents/Resources/uninstallMono.sh .
sudo ./uninstallMono.sh
rm uninstallMono.sh
http://dragthor.wordpress.com/2007/07/24/uninstall-mono-on-mac-os-x/
Work for me, OSX, But I Use the uninstall script file (.sh) from the Mono Installer Package.
Mono doesn't contain a lot of fluff, so just running those commands will be fine. It's as simple as deleting all the data folders, and the binaries.
I just deleted the mono.frameworks folder. I got tired of answering "yes" billions of times...
