How to detect size of directory in unix
Finding file size or directory size inward Unix as well as Linux is non real hard but if y'all came from windows background than it may sounds hard to y'all because y'all need to recall unix commands for file as well as directory size. This is a mutual complain from windows user when they exposed to Unix operating organization survive it Linux or Solaris. but In my persuasion having commands for doing things is to a greater extent than powerful because y'all 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 ascendency tutorial nosotros volition encounter how to detect size of file as well as directory inward unix, how to detect large files inward unix, how to detect disk infinite inward file organization as well as another file as well as directory related stuff.
This article is continuation of my before postal service on Unix e.g. 10 Example of grep ascendency inward Unix, 10 instance of chmod ascendency inward unix as well as How to kind files as well as directory inward Unix using kind command. If y'all haven’t read them already, You may detect them useful as well as interesting.
Unix Command to detect size of File
You tin role "ls" unix ascendency to detect size of whatever file inward unix. simply run ls amongst "-l" selection as well as it volition display size of file inward a column. hither is an instance of finding file size inward unix using ls ascendency : javin@localhost
$ 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 kind files based on size inward Unix. Drawback of ls ascendency is that it doesn’t display size of directory. Which nosotros volition encounter inward side yesteryear side section. Just similar find as well as grep, commands like ls, du as well as df are must known for whatever 1 who is working on Unix operating organization
How to detect directory size inward Unix
In final article nosotros accept seen basics of file as well as directory permission piece hither nosotros volition find out size of directory inward unix or linux yesteryear using ascendency "du" stands for disk usage but tin survive used to find size of whatever directory including sub directory as well as files within it. this is real useful unix ascendency because before instance of "ls -lrt" doesn't shows size of directories inward unix as well as inward many scenario especially when nosotros desire to gratis upward approximately infinite as well as desire to know how much infinite every directory is taking up. nosotros tin laissez passer on this yesteryear using unix ascendency "du".
javin@localhoste
$ du
12K ./java
45K .
$ du
12K ./java
45K .
This example of du ascendency inward unix is showing size of coffee directory equally 12K as well as electrical current directory equally 45K. but work amongst this ascendency is that it display size of private directory. Suppose y'all accept a abode directory as well as at that topographic point are several directory within abode as well as y'all desire to detect out full size of abode directory, inward that instance role “du –sh” , -s summarizes number as well as –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 ascendency interview question:
javin@localhost: /cygdrive/c/video
$ du –sh .
10G .
$ du –sh .
10G .
here nosotros accept executed du ascendency within video directory as well as it display full size of video directory including sub directories.
How to detect file organization size inward unix
Another of import matter to detect is size of file organization inward unix. Since inward Unix or Linux y'all tin accept multiple file systems as well as approximately fourth dimension a detail directory hosted on a detail file organization gets filled up. Classic instance is abode directory of user. In such scenario its of import to know that on which file organization your abode directory is mounted as well as how much infinite is left of that file system. don't worry nosotros accept a got a unix ascendency to create that for y'all as well as ascendency is "df" which displays size of file organization inward unix. You tin run "df" unix ascendency amongst electrical current directory or whatever specified directory. See below example of df ascendency inward unix to detect 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 instance shows that electrical current directory is mounted on /cygdrive/c which is 84% filled as well as full size of that file organization is 40G. ever role "-h" selection which display number inward human readable format e.g. G for Gigs , thou for megs etc.
That’s all on finding file size, directory size as well as size of file organization inward Unix as well as Linux..
