sed -i 's/original/new/g' filename.txt
This basically replaces every occurrence of the “original” string with the “new” string in the file named “filename.txt”
sed -i 's/192.168.0.1/192.168.1.1/g' /etc/fstab
Will replace all occurrences of the IP “192.168.0.1” with the IP “192.168.1.1” in the “/etc/fstab” file.
That’s it, Enjoy!
It’s Tilda! My previous best was Guake, but it’s having compatibility issues and not maintained frequently like this one.
sudo apt install tilda
Very customizable and has a lot of options, including position, colors, scroll bars and transparency.
Tested on Ubuntu 17.10 (Works ONLY on Xorg, not Wayland).

Just go to Online Accounts -> Microsoft Exchange -> Type your e-mail and password!
This basically connects using Exchange Web Services (EWS).
If this doesn’t work out with you, click on custom and enter your username and server. I had to do that in my case, since my mail server’s address was different from the mail address.
That’s it! Enjoy! Here are some screenshots showing the results :))
Note: Tested and worked perfectly in Ubuntu 17.10 (Gnome 3.26).

ffmpeg -i source_video.mp4 -t 50 -c copy output_video.mp4
This cuts the first 50 seconds of the video named source_video.mp4 and outputs them without any re-encoding to output_video.mp4
Just received a 128 GB SanDisk Extreme PRO USB 3.1 Solid State Flash Drive. I wanted to check whether its speed really matches what’s advertised of up to 420 MB/s for read and 380 MB/s for write.
Computer Used: Lenovo Thinkpad X1 Carbon
OS: Ubuntu 16.04.3
Benchmark Tool: Standard Gnome Disks Utility
Features Tested: Read Speed, Write Speed and Random Access
- 100 samples, 100 MB each for read and write tests
- 1000 samples for access time
Average Read Rate: 423 MB/s
Average Write Rate: 188 MB/s
The SanDisk Extreme PRO USB Drive Read speed is 420 MB/s as advertised, however, the write speed is much lower than the promised 380 MB/s. It’s a quite fast USB drive, especially for read, but the write speed is about half what SanDisk claims (although still very fast for a USB drive).
A more secure alternative to NFS or SAMBA would be to use SSHFS.
Besides encrypting the data stream, it has many benefits, among which:
- Firewall-friendly, since it uses standard SSH ports
- Supports PKI
To mount an SSH filesystem from Ubuntu, do the following:
sudo apt install sshfs
sudo mkdir /MountPoint
sudo sshfs username@server:/RemoteFileSystem /MountPoint
Note: You don’t need to use sudo to mount via sshfs, just make sure you have permissions on the local mount point.
I figured out it would be much easier to just use the CleanWipe utility from here: https://symwisedownload.symantec.com//resources/sites/SYMWISE/content/live/TUTORIALS/124000/HOWTO124983/en_US/CleanWipe3897.zip?__gda__=1517979685_a3d644edaa4bd0b810351c5a6cab2aa6
