I am trying to run exe file on qemu in system mode. For that, I created a compiled a kernel, buildroot and qemu based on the Prepare the environment for developing Linux kernel with qemu (also created a shared folder between the host and the guest qemu from How to share a directory with the host without networking in QEMU). Now, I want to compile and run exe on the qemu system... After compiling the pcimem project on the host, I opened qemu, moved to the shared folder and tried to run it, but I got -sh: ./pcimem: not found. When I run ls in qemu, I can see the files and that they have the right permissions:
# ls -la

What am I doing wrong ? How can I run exe on the qemu in system mode ?
Update:
I found out here that I am trying to invoke the exe file from busybox terminal, and apparently it can't be done... so I tried to invoke the next command line:
ash ./pcimem
but than I get the next error:
./pcimem: line 1: can't create #: Operation not permitted
./pcimem: line 1:ELF: not found
./pcimem: line 2: syntax error: unexpected "("

I have been having problems logging into MySQL through phpMyAdmin so I decided to uninstall both on my computer. To my surprise, I do not even have the permissions to uninstall MySQL.
I tried to uninstall MySQL using the command "sudo rm /usr/local/mysql" and the terminal returned that I did not have permission.
I looked up a StackOverflow question about not having access to /usr/local and a reply asked the user to do sudo $chown, which my terminal said I did not have permission to do.
I did have permission to do ls -la /usr/local, and this is what the terminal returned:

I am shocked about the "remotedesktop" line, but I hope it is innocent considering it shows up the same day as Homebrew. Please help me understand these results and what to do next.
You can't remove a directory with rm unless you use the recursive flag (-r). You should get an "is a directory" error, not a permissions error. You'll probably want to include the "force" flag (-f) to avoid having to confirm each deletion.
That's also a symlink so you need to remove the specific instance of it, or adapt your command to remove anything MySQL-ish using a wildcard:
rm -rf /usr/local/mysql*
As always, pay extremely close attention to what you're doing when using recursive deletes and sudo. A single space in the wrong place can utterly ruin your day. Triple check before executing these commands.
I'm attempting to get a screenshot via command line using the new features of Google Chrome 59 (Google Chrome 59.0.3071.86) in a Centos 7 box and I'm getting an error saying it could not get the download directory. I attempted to create the directory in my home folder but no success! Any suggestions?

I found an answer to this here:
https://bugs.chromium.org/p/chromium/issues/detail?id=695212
The fix is to install the google font package:
$ sudo yum install gnu-free-sans-fonts
Then this should work:
$ google-chrome --headless --disable-gpu --enable-logging -v=10 --screenshot=out.png http://www.chromestatus.com
Its been a while since i had to modify an application. Today doing another deploy I got

Why would that file changed the owner? That file was updated on Oct, the 23 but me (as the app) I'm not able to change them to root
any idea?
I believe I have the same issue though with different cartridges/application architecture so the error log is different. OpenShift help suggested to file a bug about it.
My current workaround uses manual deployments:
Disable auto deployment with $ rhc app-configure <YOUR_APP> --no-auto-deploy
$ git push origin
$ ssh <YOUR_APP>#<YOUR_APP>.rhcloud.com
$ gear build
Run gear start for all your cartridges - make sure that they run successfully
This is not optimal but hope it helps.
I am using ubuntu 14.04 and trying to import csv file but getting following error - Couldn't load the external resource at: file:/usr/share/neo4j/import/orders.csv
My query is -
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "file:///orders.csv" AS row
MATCH (order:Order {orderId: row.SalesOrderID})
MATCH (product:Product {productId: row.ProductID})
MERGE (order)-[pu:PRODUCT]->(product)
ON CREATE SET pu.unitPrice = toFloat(row.UnitPrice), pu.quantity = toFloat(row.OrderQty);
I have placed csv files at /var/lib/neo4j/import and also changed permission sudo chmod 777 -R /var/lib/neo4j/import but still not working.
file permissions are as -
sachin#sachin:/var/lib/neo4j$ ls -la

Please help!!! Thanks.
okay , I've resolved it by creating new directory import under /usr/share/neo4j , place csv files in this directory and set its permission to 777.
Explanation Since my error was Couldn't load the external resource at: file:/usr/share/neo4j/import/orders.csv and I placed my csv files at /var/lib/neo4j/import. Hope it will help others,Thanks.
Sorry in advance for my bad english...
I'm trying to clone an hg repository using Eclipse on Ubuntu.
I always have the following error message which is exactly the same when I perform a "hg clone" command :

I tried many things such as chmod and chown... I'm not a linux expert so I googled my error message but there is not many results.
Has anyone an idea about this?
Thank you very much in advance
You're right to be thinking file permissions because that's the root cause, but I'm a little confused. Are you showing up the file permissions on the server, but seeing that message on the your workstation? Where exactly are you trying to clone from and to? Are you cloning over http or ssh? What user are you running the clone command as?
