How to Fix Broken LaunchPAD GPG Import on Linux Mint ?

Users that have installed Linux Mint for the first time or have not imported a GPG key before using the command line terminal will often have issues importing GPG keys from LaunchPAD PPAs due to the directories not being created. This is an easy fix. Use the following command that will, in turn, generate the directories:

$ sudo gpg --list-keys
	
	
	
	
	
	

How to sort du -h command output by size ?

The sort command provides -h parameter allows to compare human-readable numbers (e.g., 10K 15M 1G etc). This helps up to compare the results of `du -h` and short them.

It takes the below form:

$ du -h * | sort -h
	
	
	
	

This will display the results in the ascending order by size. 

You can also reverse this using -r to show results in descending order with the below command:

$ du -h * | sort -rh
	
	
	
	

What is the du -sh * command ?

The du -sh * command  will display only a total for each argument as well as print sizes in human readable format (e.g., 1K 234M 2G).

The command takes the below form:

$ du -sh
	
	
	
	

What is df command ?

The df command displays the amount of disk space available on the filesystem with each file name's argument.

The df command can be run by any user. Like many Linux commands, df uses the following structure:

$ df [OPTION]... [FILE]...
	
	
	
	

The df command primarily checks disk usage on a mounted filesystem. If you don't include a file name, the output shows the space available on all currently mounted filesystems. 

What is the differences between the df and du command in Linux ?

While du reports files and directories  disk usage, df reports how much disk space your filesystem is using.

How to use the du Command in GB / MB / TB format ?

The du command is used to estimate file space usage. To print sizes in human readable format such as 5K, 400M, or 3G, type the following commands:

du -h
	
	
du -h /tmp
	
	
du -h /home/user
	
	
	
	

How to use du (Disk Usage) Commands to Find Disk Usage of Files and Directories in Linux ?

The du command displays the files and directory sizes in a recursive manner.

• To find out the disk usage summary of a /home/user directory tree and each of its subdirectories. Run the command as: # du  /home/folderName
• You can use the "-h" option with the "du" command to print results in "Human Readable Format". This means you can see sizes in Bytes, Kilobytes, Megabytes, Gigabytes, etc: # du -h /home/folderName
• You can get the summary of a grand total disk usage size of a directory using the option "-s": # du -sh /home/folderName
• You can use the "-a" flag with the "du" command displays the disk usage of all the files and directories: # du -a /home/folderName
• You can use the "-a" flag along with "-h" displays disk usage of all files and folders in a human-readable format: # du -ah /home/folderName
• You can find out the disk usage of a directory tree with its subtree in Kilobyte blocks using the "-k" (displays size in 1024 bytes units): # du -k /home/folderName
• You can get the summary of disk usage of directory tree along with its subtrees in Megabytes (MB) only using the "-mh" option : # du -mh /home/folderName
• You can use the "-c" flag to get a grand total usage disk space at the last line of the output: # du -ch /home/folderName

How to check the listening ports and applications on Linux ?

1. Open a terminal application i.e. shell prompt. Run any one of the following command on Linux to see open ports:

$ sudo lsof -i -P -n | grep LISTEN
$ sudo netstat -tulpn | grep LISTEN
$ sudo ss -tulpn | grep LISTEN
$ sudo lsof -i:22 ## see a specific port such as 22 ##
$ sudo nmap -sTU -O IP-address-Here

2. For the latest version of Linux use the ss command. For example:

$ ss -tulw

What Operations can AWK do ?

• Scanning files line by line.
• Splitting each input line into fields.
• Comparing input lines and fields to patterns.
• Performing specified actions on matching lines.

AWK Command Usefulness includes:

• Changing data files.
• Producing formatted reports.

What is AWK Syntax ?

It is given below:

$ awk options 'selection _criteria {action }' input-file > output-file

Two strings are equal when they have the same length and contain the same sequence of characters.

The Types of Text Editor in Linux are:

• Command-line text editors: A good example is Vim, which gives you the option of jumping into the editor from the command line. System admins will find this very useful when editing configuration files.
• Graphical user interface (GUI) text editors: This type of text editor features a GUI but cannot be used from the command line.

How do I delete an ifconfig interface ?

To delete an alias interface use:

$ ifconfig eth0:0 down 

Note: for every scope (i.e. same net with address/netmask combination) all aliases are deleted, if you delete the first (primary). 

'ifconfig eth0:0 up' flag causes the interface to be activated.
