Useful commands for checking/find Directories/Files in Solaris  

Display the Size of Directories, Sub-directories, and Files

du -summarize disk usage

(By default, file sizes are written in 512-byte units, rounded up to the next 512-byte unit.)

OPTIONS:

-a

Displays the size of each file and subdirectory, and the total number of blocks that are contained in the specified directory.

-s

Displays the total number of blocks that are contained in the specified directory.

# du -s /var/adm/

1198    /var/adm

-h

All sizes are scaled to a  human  readable  format,for  example,  34K, 244M, 5.7G, or 2.0T.

Displays the size of each directory in 1024–byte blocks.

# du -h /var/adm/

   1K   /var/adm/acct/fiscal

   1K   /var/adm/acct/nite

   1K   /var/adm/acct/sum

   4K   /var/adm/acct

   1K   /var/adm/streams

   1K   /var/adm/sm.bin

   1K   /var/adm/exacct

   1K   /var/adm/log

   1K   /var/adm/sa

 599K   /var/adm

-H

Displays the size of each directory in 1000–byte blocks.

# du -H /var/adm/

2       /var/adm/acct/fiscal

2       /var/adm/acct/nite

2       /var/adm/acct/sum

8       /var/adm/acct

2       /var/adm/streams

Using ls and find commands:

Changes the directory in to the place of files are locating

# ls [-lh] [-s]

-l

Displays a list of files and directories in long format , sizes in bytes.

# ls -l

total 115540

-rw-r--r--   1 root     root         233 May 21  2013 Cms2Serv.bak

-rw-rw-rw-   1 root     root         213 May 21  2013 Cms2Serv.ini

-rw-r--r--   1 root     root      639742 Jan  7 10:28 EMdetect_00.bin

-h

Scales file sizes and directory sizes into human readable format like Kbytes, Mbytes, Gbytes, or Tbytes when the file or directory size is larger than 1024 bytes.

# ls -l -h

total 115540

-rw-r--r--   1 root     root         233 May 21  2013 Cms2Serv.bak

-rw-rw-rw-   1 root     root         213 May 21  2013 Cms2Serv.ini

-rw-r--r--   1 root     root         54M Jan  7 10:26 EMdatabase0.sav

-rw-r--r--   1 root     root        625K Jan  7 10:28 EMdetect_00.bin

-S

Displays a list of the files and directories, showing the sizes in blocks.

# ls -s

total 115800

   2 Cms2Serv.bak     1280 EMdetect_00.bin    92 EMhist.sav         28 elementMan.cms

How to Find Large Files

If the characters or columns for the files are different, use following command to sort a list of files by block size, from largest to smallest.

# ls -l| sort +4rn | more

# ls -l | sort +4rn | more

-rw-r--r--   1 root     root     56660746 Jan  7 10:34 EMdatabase0.sav

-rw-r--r--   1 root     root      961820 Jan  7 09:58 EMhist.bak

-rw-r--r--   1 root     root      640113 Jan  7 10:33 EMdetect_01.bin

-rw-r--r--   1 root     root      639742 Jan  7 10:28 EMdetect_00.bin

drwxr-xr-x   2 root     root      233984 Jan  7 10:33 ipcfg

-rw-r--r--   1 root     root       51608 Jan  7 10:36 EMhist.sav

drwxr-xr-x   2 root     root       41472 Jan  7 09:48 ipinv

Note that this command sorts files in a list by the character that is in the fourth field, starting from the left.

If the characters or columns for the files are the same, use the following command to sort a list of files by block size, from largest to smallest.

# ls -s | sort -nr |more

Note that this command sorts files in a list, starting with the left most character.

Find Files That Exceed a Specified Size Limit

find directory -size +nnn

directory

Identifies the directory that you want to search.

-size +nnn

Nnn in 512-byte blocks. Files that exceed this size will list.

# find . -size +400 -print

./ipcfg

./ipcfg/ipdevcfg.bin

./EMdetect_01.bin

./EMdetect_00.bin

./EMhist.bak

./EMdatabase0.sav
