I am trying to run this

sed -i -e "s/'(\${RConstants\.staticPath}\/dist\/img\/app\/icons\.svg#[a-z_-]*)'/`\1`/g" test

Single quote version

sed -i -e 's/'\''(\${RConstants\.staticPath}\/dist\/img\/app\/icons\.svg#[a-z_-]*)'\''/`$1`/g' test

Content of test file:

useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');    useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');
    useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');

Basically I need to replace single quote with back tick.

The problem is that I tried doing the sed command with single quotes and with double quotes, each having its own problem.

With double quotes, I'm getting 1: command not found and with single quotes, it doesn't replace anything.

Ubuntu 18.04.01 upgraded from 16.04

Shift Alt Down does not work in PHPStorm. Also, I can't assign any shortcut to it and it is not recognized as a shortcut (but top, left, and right do get recognized.

I use PHPStorm and cannot do a Move Line Down because of this.

cat /etc/default/keyboard
XKBLAYOUT=us
XKBVARIANT=intl
BACKSPACE=guess

EDI: I have reinstalled the OS (18.04.1) just to ensure it wasn't a problem with updating. BUT I kept my home folder. It doesn't work either. But my Gnome extensions are there, so maybe there is a config directory for it in my home folder? Previous to reinstall, I renamed the folders gconf, gnome and compiz in the home folder.

Is there a plugin for GNome to make the top left most pixel click the Close button?

I have already moved the Windows Contols to left, but when I do a fast "move top left" to close the window, it does not trigger any action, and I have to move a few pixels down to click it.

Where are username and password stored when you set System Wide Proxy in Settings -> Network?

I'm trying to find this file to configure an Ubuntu Server that does not have GUI.

How to read the Ubuntu version information there? Because to me it seems that newer release is targeted with an older PHP sqlite version.

The problem:

My DNS is getting hijacked by my ISP, when I enter a webpage, sometimes it redirects me to "Download Bill" page.

I've tried to see why this happens, then I found something else. I have DD-WRT in my router, with DNSMASQ for DHCP and DNS, with fixed DNS IPs (Open DNS).

But in Ubuntu, my resolv.conf shows it is using 127.0.0.1 (and so does nslookup), so not querying the router? But then Connection Info shows the right information.

What is wrong here?

There is a file in /etc/sudoers.d/90-cloudimg-ubuntu that makes the Ubuntu user passwordless for sudo.

However, in /etc/sudoers the 'include' line is commented.

How then is that config loaded?

We are using fail2banin our servers, and I'm getting banned randomly from them, even if I log in successfully, after typing some chars I get banned.

Also, when I do scp, it sometimes starts copying files then I get banned.

I'm the only one in the network that is having this issue.

How can I see if there is some malware in my Ubuntu 16.04 installation? Or maybe some network administrator is sniffing my traffic and causing this?

I'm using encrypted disk, and terminal to connect.

I was testing the brightness, opacity and saturation plugin and dropped the brigthness to 0, now without having apply (but pressed ESC), I can´t control my Ubuntu anymore (all windows are black). How can I recover from this?

How can I really know that Ubuntu 14.04 finished copying in my USB pendrive that does not have an activity led?

For example, I connect it to the USB 3 port (pendrive is USB 3) then it shows like it finished copying (100% then dialog closes). After 2 mins and when I put the pendrive in another PC, a warning shows up in Ubuntu that it couldn't finish copying, and the file was corrupted in my pendrive.

So, is there a way to actually trust Ubuntu when it says that it finished copying something?

I have 2 DNS configured in network manager for my connection (Selected DHCP Addresses only).

The DNS are working good if used with nslookup.

/run/resolvconf/resolv.conf

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search domain.tld #edited

What dns is running on 127.0.1.1?

If I run nslookup thehost it won't work. But if I run nslookup thehost 192.168.1.4 (the dns configured in network manager) it works.

So I would like to know which DNS is nslookup going through and what is happening after it. I suppose it is going to 127.0.1.1 but then I don't know which is this one (dnsmasq doesn't seem to be installed) and what it is doing.

I had 12.04 without problems, but since I upgraded to 14.04, I'm noting the system is very slow for UI tasks, and when I get to work the next day (computer stays on), and I type the passwords, it takes like 1 minute to log in.

However, top or htop doesn't show significant CPU usage. It is so slow that writing this post and right clicking in a word for corrector to work takes 10 secs to show the menu and mouse pointer teleports when I move it.

Now that I have closed VirtualBox is much better so I think the problem may come from there.

VirtualBox is 4.3.10_ubuntu and the VM is Win7 with "Use 3d acceleration" marked.

But since htop is not showing considerable CPU usage, what do you think could be the cause of this?

I would like to have all icons in the same size, and in a ruled desktop. Currently if I try to order my Desktop Icons they can be stacked on top of another, and I hate that, because if I try to place an icon in the middle of other 2, it gets, literally, in the middle, not replacing the bottom one and making it move one place like in Windows.

Thanks!

Problem: In Ubuntu 12.04 and 14.04, if you try to use internal mic, it gets a lot of static and is almost impossible to hear on the other side because of extremely low sound (voip calls).

Recorder might work.

Is there a way to get absolute path of a file that is being searched?

For example:

find .. -name "filename"

It gives me results like ../filename but I want the full path.

What I need is to find in the parent directory and its children, for a specific file, that I will use in another script later.

Thanks

This is my /etc/default/grub:

But when I have a power failure, then the Ubuntu Server 12.10 stays at this screen. I've tried to solve it editing grub but doesn't seem to have an affect. Since I don't have display attached, I need it to start automatically Ubuntu every time.

Thanks!

Is it possible to make lpstat output print jobs in reverse order, from newer to older? Starting from the end of file?

Currently we see in the output the first sent document, then the second, etc.

I have more than 5K jobs and I want to output only the ones new for me, cancelling the cycle once I reach the last job id I printed in screen.

I've installed Ubuntu 13.04, I want to install doublecmd (Double Commander). I've added the PPA, but when I update its looking at dists/raring/main.

Its not there, but it's on Precise.

How could I do to make it look in precise directory?

I want to make Shift Switcher to select window on release, like Alt+Tab

I currently have Super+Tab configure for Next Window in Workspace, so I press it and move windows, but when I release, I have to press Enter or Shift to get to the window. This isnt the normal behaviour with the default key for Previous Window, Shift+Super+Tab, which changes to the selected window on release.

How can achieve this, or is it a bug?

Thanks a lot.

I've installed Ubuntu 12.04 in an Acer Timeline X 5830TG and brightness controls were not working (Fn + Key), even the Ubuntu's one.
