UNIX for Dummies Questions & Answers

To keep it going, you can put the whole thing within a while
loop, and get rid of the "exit" when it doesn't find a file.

Here is a good shell scripting web page, and the specific page
with the while loop:

http://www.scit.wlv.ac.uk/~jphb/spos...ell.index.html
http://www.scit.wlv.ac.uk/~jphb/spos...ll/shell7.html


as for getting rid of the ./
There is probably a hardcore, regular expression guru way to do it,
but here is an easier way i found:

echo "./Gtest" | sed -e 's/G//g' | cut -c3-


come to think of it, you probably don't even need sed.
you might be able to just use:
cut -c4-

My motto is to avoid complicated regular expressions
unless I CANNOT find a better and easier way.

You shoudln't need the temp.
I only put it there to point out that you have to be getting
the filename from standard output somewhere.

That pipe you did should be alright.

Thank you!

gjduff, you still there? I'm trying to make the script check every 10 seconds for a new file then update a logfile. Can you see what I'm missing?

Thanks,

#!/bin/ksh

LOGFILE=logs/gfiupload.log
NEW=`find . -type f -name "G*" -newer newtime`

while true; do
if
[ -z $NEW ]; then
echo "bombing..." >>$LOGFILE
touch newtime
sleep 10

else
FILE=`echo $NEW | sed -e 's/G//g'`
echo `date +%m%d%Y_%H:%M`: New file found: $FILE >>$LOGFILE
mv newtime oldtime
touch newtime
fi
sleep 10
done

Looking at the code, I don't immediately see the problem.
I'll have to grab the code and try it out for myself.

I gather you are running it in the background? (not that
this necessarily matters)

Anyways, I've got a fairly busy day, but I'll try and get back to
you ASAP.

Oh, wait a sec.

before I attempt any debugging, I'll point out that possibly 10 seconds
is too short of a time for one of those G* files to actually get a timestamp on
them that is newer than the "newtime". (the file timestamps seem to be to the minute
on my machine)

Due to that, Possibly, you should only "touch newtime"
if a new file, is found. When it is bombing, maybe don't do it.

I should have tried it before opening my mouth.
anyways, this works:

Code:

#!/bin/ksh

LOGFILE=logs/gfiupload.log


while true; do

NEW=`find . -type f -name "G*" -newer newtime`

#echo "here"
#echo $NEW

if [ -z $NEW ]; then
	echo "bombing..." >>$LOGFILE
	#touch newtime
	sleep 10

else
	FILE=`echo $NEW | sed -e 's/G//g'`
	echo `date +%m%d%Y_%H:%M`: New file found: $FILE >>$LOGFILE
	mv newtime oldtime
	touch newtime
fi

sleep 10
done
