HoCo_'s questions

I would remap my keyboard as following:

xmodmap -e "keycode 77= w W {" 
xmodmap -e "keycode 78= x X }"

xmodmap -e "keycode 24= a A @"
xmodmap -e "keycode 49= ` & 2"
xmodmap -e "keycode 65= space space _"

xmodmap -e "keycode 111= Up Up Down"
xmodmap -e "keycode 113= Left Left Right"


xmodmap -e "keycode 51= * \" \' "

xmodmap -e "keycode 113= Left Left Right"
xmodmap -e "keycode 113= Left Left Right"

But xmodmap returns me:

xmodmap: commandline:1: bad keysym name 'XF86XK_{' in keysym list

I have seen on the web I should firstly remove the key but I m wondering if that could create some bug, so before trying a move I would ask the community some advice,

thanks

Yesterday I have make a nooby-break using sudo / ., meaning "hey move all my boot files and all in my user session tree folder", I have forgot the dot behind my slash as following ./ .

I'm trying to reboot and I have since followed several progression points, here an abstract of my previous step:

• firstly I have tried to boot with a USB-live with Ubuntu on it. But i couldn't login neither access a tty since there was a problem with grub or something like that so I have open grub and fallen on grub-rescue.
• Then I have remembered that I have moved all my boot-files inside the tree so I have started to seek for how to move-back theses files.
• I have meanwhile find a topic in which someone have done something similar to me, he explains in how to connect and prefix the root in grub rescue, here the topic: grub rescue / move folder.
• I have hence managed on Grub rescue to set my root and prefix on the folder in which I have moved all my boot-files.

• Then I have emerged from grub rescue to grub, and after some googling, I have passed the following commands in grub:

  grub> linux /home/path_to_boot/boot/vmlinuz-3.xx.x-67-generic
  grub> initrd /home/path_to_boot/boot/initrd.img-3.xx.x-67-generic
  grub> boot
  

Now my computer have started the boot and manage some steps, then returns me three errors:

• firstly

  on initramfs: mounting can't find /root in /etc/fstab/mounting.

• secondly

  /root/run failed: no such file or directory

• finally

  target file system doesn't have requested /sbin/init or /bin/init maybe -I have noted sbin but usually is rather bin?

Here a snapashot of my current situation, you will see at the top of my image the list of folder in my "/" mount directory - ls command.

So that it, I don't know what should I do in particular, I'm very happy having manage grub rescue, now I would have advice about how handle my situation furthermore.

Any hint would be great, Thanks!

I'm working with command line and sometime some informational - as manuals readMe and all - output are very large and hard to read in a one shot from the command's line. I wonder how open it directly on a text editor ?

I have tried gedit man node but it does'nt work. If any have some hint, would be gr

I wonder if it is possible to make chain actions in Ubuntu terminal like:

action 1 on objectA . then action 2 on objectA 

without having to repeat the name of objectA anymore.

Example:

touch file.js && openEditor "$1" 

or something like that.

I'm trying currently to use the xmodmap -e function in order to remap my keyboard. I want to replace the twosuperior key with greater and less depend of the asciitilde mode being activated.

I talk about asciitilde or grave mode in reference to this convention

I wonder how remap the "asciitilde mode layout" since I retrieve the same keycode for the "grave mode layout" and "asciitilde mode layout".

Here what I retrieve with the xev process :

// retrieving less
keycode 94 (keysym 0x3c, less)"<" 

// passing in asciitilde layout mode
keycode 50 (keysym 0xffe1, Shift_L),

// retrieving greater with asciitilde mode activated
keycode 94 (keysym 0x3e, greater)">"

 ------------------

// retrieving the code of twosuperior key 
keycode 49 (keysym 0xb2, twosuperior) "²"


// passing in asciitilde layout mode activated
keycode 50 (keysym 0xffe1, Shift_L)

// retrieving the code of twosuperior key with asciitilde being activated  
keycode 49 (keysym 0x0, NoSymbol)

As you can see I retrieve the same keycode for grave layout mode and asciitilde layout mode.

How can I make change on asciitilde layout key map ?

Thanks

Edit : other answer talked about change the title of the terminal, not a tab, but effectively they answer to my question too. Everything is great.

I'm a newbie and I wonder how give a specific name to a terminal tab instance ?

Here an instance of my question :

Currently I have just few knowledge in Ubuntu system. Thanks

I am trying to organize my computer's file management system, for this purpose. How can I change the file colors in Ubuntu to distinguish each of them easier?
