UNIX - More of searching for files

From the previous post....

In order to locate large directories, I extended the idea of the find statement and an executable script (ascr2)

In this example, I use the du -sm command to locate directories exceeding a certain size in MB.

File - ascr2 Parameter 1 in the directory name, parameter 2 is the minimum size we want to display.

if [ `du -sm $1 | cut -f1` -gt $2 ]; then
echo "$1 - `du -sm $1 | cut -f1`"
fi

The File Command. This will only display directories over 100Mb. Obviously the parent directories will be larger.

find /app/oracle -type d -exec ./ascr2 {} 100 \;

UNIX - finding directories with more than x number of files

I had to scratch my head a little when I was supporting Oracle in a Unix/Linux/AIX environment. We would keep getting tickets for partition /app/oracle exceeds 90%.

So I'd log into the server and do a df -h /app/oracle or df -g /app/oracle (in AIX) and sure enough it exceed 90% full.
But which files should I delete or gzip?

So I'd do this...

find /app/oracle -type f -size +100000 -exec ls -l {} \;

to locate large files, and this to locate dump files.

find /app/oracle -name '*.dmp' -exec ls -l {} \;

but the biggest problem is with large numbers of small log files clogging up directories. Icouldn't find a suitable unix command so I wrote one.

File - ascr1 (this will display the count of files in directory $1 but only if it exceed the number in $2). Give it execute privs.

if [ `ls $1 | wc -l` -gt $2 ]; then
echo "$1 - `ls $1 | wc -l`"
fi

then use it in a find command. In this example it will only display directories exceeding 1000 files.

find /app/oracle -type d -exec ./ascr1 {} 1000 \;
