Top Ten Console Teams

In this post I will talk about the most interesting commands that can be very useful when working in the console. There are no unambiguous criteria for determining which team is better than the other - each one chooses the best for his conditions. I decided to build a list of teams based on the top rated console tricks from commandlinefu.com, a pantry of console teams. The result of executing one of these commands under Linux is shown in the picture. If interested, please, under cat.

Tenth place

Enter the last argument of recent commands. While holding ALT or ESC, with each click on a point, the parameters of previous commands, from recently entered to old ones, will be substituted into the input line.

Комбинация 'ALT+.' или ' .'

Ninth place

Reinitialization of the terminal without ending the current session. For example, in the case when binary data were output to the terminal and it stopped working correctly.

reset

Eighth place

Creates an empty file. Destroys the contents of a file without deleting it.

> file.txt

Seventh place

Running a command with a space in front of it does not save it in history. It may come in handy when transferring passwords to open programs.

<пробел>команда

Sixth place

Starting the editor to enter a complex command or script, the choice of the editor is determined by the variable $ EDITOR

Комбинация 'CTRL+X E'

Fifth place

The My Traceroute utility is more efficient than the combination of traceroute and ping. The mtr utility combines the functionality of traceroute and ping, allowing you to conduct network diagnostics in a more visual way.

mtr google.com

Fourth place

Running the previous command with replacing the substring in it, for example, from foo to bar. Useful for typos. If you enter just ^ foo, then in the previous command the first occurrence of foo will be deleted.

^foo^bar

Third place

Return to the previous working directory. It may come in handy for switching back and forth between two directories.

cd -

Second place

Starting the HTTP server in the current directory on port 8000. If there is no index.html file in the directory, then its listing will be shown.

python -m SimpleHTTPServer

First place

Run the last command as root.
Useful when you forget to use sudo for a command. "!!" - substitutes the last entered command.

sudo !!

I hope everyone will find something new and interesting for themselves in this rating.
