You can check the size of files and sort them by using the ls command. You can find files that exceed a size limit by using the find command. For more information, see ls(1) and find(1).
Change to the directory where the files you want to check are located.
Display the size of the files.
$ ls [-lh] [-s] |
-l |
Displays a list of files and directories in long format, showing the sizes in bytes. (See the example that follows.) |
-h |
Scales file and directory sizes into Kbytes, Mbytes, Gbytes, or Terabytes when the file or directory size is larger than 1024 bytes. This option also modifies the output displayed by the -o, -n, -@, and -g options to display file or directory sizes in the new format. For more information, see ls(1). |
-s |
Displays a list of the files and directories, showing the sizes in blocks. |
The following example shows that the lastlog and messages files are larger than the other files in the /var/adm directory.
$ cd /var/adm $ ls -lh total 148 drwxrwxr-x 5 adm adm 512 Nov 26 09:39 acct/ -rw------- 1 uucp bin 0 Nov 26 09:25 aculog drwxr-xr-x 2 adm adm 512 Nov 26 09:25 exacct/ -r--r--r-- 1 root other 342K Nov 26 13:56 lastlog drwxr-xr-x 2 adm adm 512 Nov 26 09:25 log/ -rw-r--r-- 1 root root 20K Nov 26 13:55 messages drwxr-xr-x 2 adm adm 512 Nov 26 09:25 passwd/ drwxrwxr-x 2 adm sys 512 Nov 26 09:39 sa/ drwxr-xr-x 2 root sys 512 Nov 26 09:49 sm.bin/ -rw-rw-rw- 1 root bin 0 Nov 26 09:25 spellhist drwxr-xr-x 2 root sys 512 Nov 26 09:25 streams/ -rw-r--r-- 1 root bin 3.3K Nov 26 13:56 utmpx -rw-r--r-- 1 root root 0 Nov 26 10:17 vold.log -rw-r--r-- 1 adm adm 19K Nov 26 13:56 wtmpx |
The following example shows that the lpsched.1 file uses two blocks.
$ cd /var/lp/logs $ ls -s total 2 0 lpsched 2 lpsched.1 |
Display the size of files in blocks from largest to smallest.
$ ls -s | sort -nr | more |
sort -nr |
Sorts the list of files by block size from largest to smallest. |
In the following example, the lastlog and messages files are the largest files in the /var/adm directory.
$ cd /var/adm $ ls -s | sort -nr | more 48 lastlog 30 messages 24 wtmpx 18 pacct 8 utmpx 2 vold.log 2 sulog 2 sm.bin/ 2 sa/ 2 passwd/ 2 pacct1 2 log/ 2 acct/ 0 spellhist 0 aculog total 144 |
To locate and display the names of files that exceed a specified size, use the find command.
$ find directory -size +nnn |
directory |
Identifies the directory you want to search. |
-size +nnn |
Is a number of 512-byte blocks. Files that exceed this size are listed. |
The following example shows how to find files larger than 400 blocks in the current working directory.
$ find . -size +400 -print ./Howto/howto.doc ./Howto/howto.doc.backup ./Howto/howtotest.doc ./Routine/routineBackupconcepts.doc ./Routine/routineIntro.doc ./Routine/routineTroublefsck.doc ./.record ./Mail/pagination ./Config/configPrintadmin.doc ./Config/configPrintsetup.doc ./Config/configMailappx.doc ./Config/configMailconcepts.doc ./snapshot.rs |
