conditional mail on find?

[Anna Fong]

I want to send myself an email only if find cmd locates a file over a certain size.

I tried this but it always sends a message, which isn't what I want.

find / \( -name myLog.out' \) -size +1c -exec cat {} \; | mail user@domain

Is what I'm attempting even possible without having to create a script?

Hi Anna:

Well, I suppose anything that fits on a command line isn't a script (or is it?) :-))

Try this:

# find /tmp \( -name 'myLog.out' -a -size +0c \) |[ `wc -c` != 0 ] && mailx -s "BigFile" root < /dev/null

find / -name myLog.log -size +c -exec cat {} \; |mailx -s "File is too big" user@domain

Hi (again) Anna:

You will need to change my example to fit your needs (of course). That is, I offered a working "script" that probes the /tmp directory for a file named "myLog.out" with a size of zero bytes -- quite convenient for testing the logic...

Wilfred,

Your example does the same as mine -- always sending a file. I want the mail to be conditional. Nice try.

James,

Yes, thanks. Did modify your example for my needs. In fact, wanted the contents of the log sent to me, so here is what I did --

find / \( -name 'myLog.out' -a -size +0c \) |[ `wc -c` != 0 ] && mail user@domain < myLog.out

For extra points, how to set find statement to a variable and then reuse variable for redirecting to mail?

Hi Anna:

By example, consider this:

# DIR=/tmp
# NAME=myLog.out
# SIZE=500
# find ${DIR} \( -name ${NAME} -a -size +${SIZE}c \)

Regards!

hi,

i usually do it this way:
#=============================
#!/bin/sh
emailadd1=yogeeraj@mymailserver.mu
DIR=/tmp
NAME=105.sh
SIZE=5
m=`find ${DIR} \( -name ${NAME} -a -size +${SIZE}c \)`

/usr/bin/uuencode $m "logfile_needed.log"|mailx -m -s "The is the file you need - `date`" $emailadd1

#=============================

Hope this helps!

James,

Thanks again for the example. This is what I ended up with (all on one line) --

# FPATH=/path/to; FNAME=myLog.out; find ${FPATH} \( -name ${FNAME} -a -size +0c \) |[ `wc -c` != 0 ] && > mail user@domain < "${FPATH}/${FNAME}"

Yogeeraj,

Thanks for your example. Didn't try it out because I ended up doing this --

# FPATH=/path/to; FNAME=myLog.out; find ${FPATH} \( -name ${FNAME} -a -size +0c \) |[ `wc -c` != 0 ] && > mail user@domain < "${FPATH}/${FNAME}"
