Is there somebody that uses Windows a lot that keeps messing up your Linux machine? Press Ctrl+Alt+F1-F6 and run this command after logging into a text shell!

I don't think it's possible to give a (background) colour to the tab itself, since a tab is, IIUC, simply a command to the terminal to move to the right. Nevertheless, this "highlighting" can be helpful when working with tab-separated files.

Btrfs reports the inode numbers of files with failed checksums. Use `find` to lookup the file names of those inodes.

Use gstreamer to capture v4l2:///dev/video0 and show ascii art video in display.

Returns any file in the folder which would be rejected by Gmail, if you were to send zipped version.

(Yes, you could just zip it and knock the extension off and put it back on the other side, but for some people this just isn't a solution)

EXACT time in Germany. :)

Can't see it here, but the non-breaking space is highlighted :)

Of course,

achieves something similar, but less colourful.

Could add more code points from https://en.wikipedia.org/wiki/Space_%28punctuation%29#Spaces_in_Unicode

Saves you an

So simple and time-saving.

Reverts the changes that were made in a particular revision, in the local working copy. You must commit the local copy to the repository to make it permanent.

This is very useful for undoing a change.

You can revert multiple changes by specifying numbers wider apart; Just remember to put the highest number first.

Removes the given string from all files under the given path - in this case the path given is "." This demonstrates the characters that must be escaped for the grep and sed commands to do their work correctly. Very handy for fixing hacked html files.

this is great if you loose you ssh connection (with out a screen session) or are working on a laptop with a bad battery, or just a power outage.

Modifications: you may not need the -print; the mtime is last modified time in days

Really, you deserve whatever happens if you have a whitespace character in a file name, but this has a small safety net. The truly paranoid will use '-i'.

In these command i use lynx to get the top trend topic of Mexico, if you replace Mexico with other country, you will get the #1 Trending topic

using awk

missed the last char thanks @Josay

Open all files which have some string go directly to the first line where that string is and run command on it.

Other examples:

Run vim only once with multiple files (and just go to string in the first one):

Run vim for each file, go to string in every one and run command (to delete line):

This command will scan the subnet and exlude duplicates

Find the length of the longest line of code in your files.
