How to honor size of directory in unix
Finding file size or directory size inward Unix in addition to Linux is non real hard but if you lot came from windows background than it may sounds hard to you lot because you lot need to retrieve unix commands for file in addition to directory size. This is a mutual complain from windows user when they exposed to Unix operating organization hold out it Linux or Solaris. but In my persuasion having commands for doing things is to a greater extent than powerful because you lot tin write powerful scripts for removing large files or taking backup of directories inward unix which is non possible amongst GUI based operating systems similar Windows. In this unix ascendence tutorial nosotros volition come across how to honor size of file in addition to directory inward unix, how to honor large files inward unix, how to honor disk infinite inward file organization in addition to another file in addition to directory related stuff.
This article is continuation of my before post service on Unix e.g. 10 Example of grep ascendence inward Unix, 10 illustration of chmod ascendence inward unix in addition to How to variety files in addition to directory inward Unix using variety command. If you lot haven’t read them already, You may honor them useful in addition to interesting.
Unix Command to honor size of File

$ ls -lrt
full 1.0K
-rwxr-xr-x 1 javin None 109 Jul 2 2011 bashparameterexample.sh*
drwxr-xr-x+ 1 javin None 0 October 8 09:04 java/
$ ls -lrt
full 1.0K
-rwxr-xr-x 1 javin None 109 Jul 2 2011 bashparameterexample.sh*
drwxr-xr-x+ 1 javin None 0 October 8 09:04 java/
ls –S fifty-fifty variety files based on size inward Unix. Drawback of ls ascendence is that it doesn’t display size of directory. Which nosotros volition come across inward adjacent section. Just similar find in addition to grep, commands like ls, du in addition to df are must known for whatever 1 who is working on Unix operating organization
How to honor directory size inward Unix
In terminal article nosotros accept seen basics of file in addition to directory permission land hither nosotros volition find out size of directory inward unix or linux yesteryear using ascendence "du" stands for disk usage but tin hold out used to find size of whatever directory including sub directory in addition to files within it. this is real useful unix ascendence because before illustration of "ls -lrt" doesn't shows size of directories inward unix in addition to inward many scenario peculiarly when nosotros desire to gratis upward unopen to infinite in addition to desire to know how much infinite every directory is taking up. nosotros tin laissez passer on this yesteryear using unix ascendence "du".
javin@localhoste
$ du
12K ./java
45K .
$ du
12K ./java
45K .
This example of du ascendence inward unix is showing size of coffee directory every bit 12K in addition to electrical flow directory every bit 45K. but work amongst this ascendence is that it display size of private directory. Suppose you lot accept a dwelling occupation solid directory in addition to in that place are several directory within dwelling occupation solid in addition to you lot desire to honor out full size of dwelling occupation solid directory, inward that instance role “du –sh” , -s summarizes consequence in addition to –h displays inward human readable format e.g. M for Mega , G for Gigs. Here is an example of finding full size of directory inward Unix which is too a real popular Unix ascendence interview question:
javin@localhost: /cygdrive/c/video
$ du –sh .
10G .
$ du –sh .
10G .
here nosotros accept executed du ascendence within video directory in addition to it display full size of video directory including sub directories.
How to honor file organization size inward unix
Another of import affair to honor is size of file organization inward unix. Since inward Unix or Linux you lot tin accept multiple file systems in addition to unopen to fourth dimension a detail directory hosted on a detail file organization gets filled up. Classic illustration is dwelling occupation solid directory of user. In such scenario its of import to know that on which file organization your dwelling occupation solid directory is mounted in addition to how much infinite is left of that file system. don't worry nosotros accept a got a unix ascendence to produce that for you lot in addition to ascendence is "df" which displays size of file organization inward unix. You tin run "df" unix ascendence amongst electrical flow directory or whatever specified directory. See below example of df ascendence inward unix to honor out size of a directory along amongst infinite left inward file system.
javin@localhost /cygdrive/c/
$ df -h .
Filesystem Size Used Avail Use% Mounted on
C: 40G 33G 6.6G 84% /cygdrive/c
$ df -h .
Filesystem Size Used Avail Use% Mounted on
C: 40G 33G 6.6G 84% /cygdrive/c
above illustration shows that electrical flow directory is mounted on /cygdrive/c which is 84% filled in addition to full size of that file organization is 40G. e'er role "-h" pick which display consequence inward human readable format e.g. G for Gigs , grand for megs etc.
That’s all on finding file size, directory size in addition to size of file organization inward Unix in addition to Linux..
