Linux check file and directory size


Linux beginner tips.

How to check file size in Linux in Gigabytes or Megabytes?

How to check directory size in Linux in human readable format?

Normally log files if left not monitored the size capacity will grow larger over time.

To check the size of a log file or basically any files on Linux.

Just type:

      ls -lh mail.log

   dir -h mail.log

Output is similar to this: -rw------- 1 xuser xuser 3.2G Jul 20 00:54 mail.log

mail.log is the file queried for its size capacity, it can be any files on the directory.

Like:  ls -lh myVideo.mkv 

       dir -h mySong.mp3

To check the size of a directory type:

Let's say on /home/xuser directory there is a folder name "video".

To check the size of the folder name “video” browse to the folder path.

cd /home/xuser

/home/xuser # du -ah video | tail -n 1

Output will be as simple as: 257G video

It means that the folder “video” has a size capacity of 257GB.

tail -n 1 tells Linux to display only the last line which is basically the total capacity of the folder.

If tail -n 1 is omitted; if video has a lot of sub folders then all of the sub folders will be displayed.

So to have a clean output, just include “tail -n 1” to display the last line which contains the total capacity of the folder.

To display the size of the mounted partitions on Linux just type: df -h

It will display the size for all the mounted partitions on the system.

-h parameter tells the system to display the output in human readable format.

Just a quick tips for Linux.



Hope it helps...Cheers!!!

Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
