Ls -al / du

// UNIX 6.1

I have /opt directory growing so fast, and /opt has a number of sub-directories.

Is there a way to display files larger than 100 MB on /opt and its sub-directories?

I like to have the file names, their sizes, and their filesystem path (/opt/xxx) in desc order.

Please advise.

Thank you!

Would it be possible to convert the size into MB and then sort them by descending order of the file size?

PHP Code:

Daniel,
is it the output of the find command? I ask this because the biggest file is ~10MB.

You mentioned UNIX 6.1, did you mean AIX 6.1? If so, then try:

Code:

find /opt -type f -size +100000000c -exec ls -l  {} \;

Quote:

Yes, the above find command should print files greater than 100000000 bytes (~100MB). Then extend the find command like so

Code:

find /opt -type f -size +100000000c -exec ls -l  {} \; | sort -nrk5,5 | awk '{$5=$5/1024/1024}1'

Sample output (before sort & awk):

Code:

-rw-r-----   1 oracle   dba      104865792 Jan  1 00:00 ./example01.dbf
-rw-r-----   1 oracle   dba      513810432 Jan  1 00:00 ./system01.dbf
-rw-r-----   1 oracle   dba      272637952 Jan  1 00:00 ./sysaux01.dbf

Sample output (after sort & awk):

Code:

-rw-r----- 1 oracle dba 490.008 Jan  1 00:00 ./system01.dbf  # 490 MB
-rw-r----- 1 oracle dba 260.008 Jan  1 00:00 ./sysaux01.dbf  # 260 MB
-rw-r----- 1 oracle dba 100.008 Jan  1 00:00 ./example01.dbf # 100 MB

Hope this helps.

Another option. I don't know if this works with AIX, but

Code:

du -sh $(find /opt -type f -size +10M) | sort -nr

produces these results (files larger than 10MB):

Code:

 59M	/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports.tar
 26M	/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/base.tar
 11M	/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/PortIndex
