q. How do I find all the large files in the directory?

a.

1) syntactic for RedHat / CentOS / Fedora Linux

Find {/ path/to/directory/}-type f-size + {size-in-kb} k-exec ls-lh {}\; | awk'{print $9 ":" $5}'

Example:

Find files greater than 50MB in the current directory

$find. -type f-size + 5000k-exec ls-lh {}\; | awk'{print $9 ":" $5} "

Find files whose directory / var/log is greater than 100MB

# find / var/log-type f-size + 100000k-exec ls-lh {}\; | awk'{print $9 ":" $5}'

2) syntactic for Debian / Ubuntu Linux

Find {/ path/to/directory}-type f-size + {file-size-in-kb} k-exec ls-lh {}\; | awk'{print $8 ":" $5}'

Example:

Find files greater than 10MB in the current directory

$find. -type f-size + 10000k-exec ls-lh {}\; | awk'{print $8 ":" $5}'

Sample output:

. / .kde / share/apps/akregator/Archive/http___blogs.msdn.com_MainFeed.aspx?Type=AllBlogs.mk4: 91M

. / out/out.tar.gz: 828M

. /. Cache/tracker/file-meta.db: 101M

. / ubuntu-8.04-desktop-i386.iso: 700M

. / vivek/out/mp3/Eric: 230M

List the files with a file size less than 500b in the home directory:

$find $HOME-size-500b

OR

$find ~-size-500b

List the files with a size of 20 512-byte blocks in the root directory:

# find /-size 20

Perl tip: display large files

Displays the occupancy of each directory under the current directory according to the file size from small to large (note: asterisk and asterisk length)

Du-k | sort-n | perl-ne'if (/ ^ (\ d +)\ s + (. * $) /) {$l=log ($1mm.1); $m=int ($l/log (1024)); printf ("% 6.1f\ t% s\ t% 25s% s\ n", ($1 / (2cm * (10cm), (("K", "M", "G", "T", "P") [$m]), "*" x (1.5cm), $2);}'

Ls command: find the largest file in the directory

You can also use the ls command:

$ls-lS

$ls-lS | less

$ls-lS | head + 10

Ls command: find the smallest file in the directory

As follows:

$ls-lSr

$ls-lSr | less

$ls-lSr | tail-10

Other lessons for you:

Find. -xdev-printf'% s% p\ n' | sort-nr | head-20

Du-xak. | sort-n | tail-50
