Let's say we want to know the size of a file, folder or hard disk space on our server and we don't have a graphical interface. How do we do it?
See the size of files and folders with "du".
There are several ways to accomplish this. Let's look at some simple commands to run applications that are already installed, usually on all systems. If we want, for example, to know the size of an .iso or a specific folder, we can use du.
$ du -bsh /fichero_o_carpeta
Du has more options, but in this case I use these 3:
- -b [–bytes]: Show in bytes.
- -s [–summarize]: Show only the total size of each argument.
- -h [–human-readable]: Prints sizes readable (eg, 1K, 234M, 2G)
See disk space with "df".
To see the space I always use the command «df»It seems to me that it is the most comfortable to read. Its use is very simple, we just have to put:
$ df -h
This will return the mounted partitions, the use of space in each one and what remains of the rest, and everything in an easy to read way.
Other data with tree.
Another very interesting command is «tree»Or what is being in Spanish« tree »😀 We have to install it and if we use this command we will obtain very interesting results.
$ sudo aptitude install tree
and try these variants:
$ tree /directorio
$ tree -h /directorio
$ tree -dh /directorio

Very useful post!
As a complement: If you run df -hT, with the T, you can see the type of filesystem for each mount point: ext4, xfs, etc.

This post reminds me of timelessness, and the relative of space time.
Open source is always useful. 😉 and with the friends of DesdeLinux and Let's UseLinux, more accessible.

WOW
We are in the year 2032 and it still serves hahaha
I read this post in March 2017 and today I have tried it but filtering the result with grep
df -hT | grep sd
where sd is the hard drive or hard drives that we have installed.
I tried it this way
df -hT | grep sd
Very interesting post. To add, it is possible to sort the output of du -h (which shows the result in MB, GB,…) by passing the output to the sort -h command. With the -h of sort you can sort the output of du -h by size.

Required arguments for long options are also required
for short options.
-a, –all include dummy file systems
-B, –block-size = SIZE scale sizes by SIZE before printing them; eg
–Direct show statistics for a file instead of mount point
–Total produces grand total
-h, –human-readable print sizes in human readable format (eg, 1K 234M 2G)
-H, –si likewise, but use powers of 1000 not 1024
-i, –inodes display node-i information instead of using blocks
-k as –block-size = 1K
-l, –local limits the listing to local filesystems
–No-sync does not call sync before getting how to use
–Output [= FIELD_LIST] uses the output format defined by
-P, –portability uses POSIX format for output
–Sync calls sync before getting how to use
-t, –type = TYPE restricts the listing to file systems of type TYPE
-T, –print-type shows the type of the filesystem
-x, –exclude-type = TYPE restricts the listing to filesystems that are not of type TYPE
-v (has no effect)
–Help displays this help and ends
–Version reports the version and exits
awesome, june 2o18 and the xd cheat still works
