Top Forums Shell Programming and Scripting shell script - search a file and perform some action Post 302451779 by gauravah on Wednesday 8th of September 2010 03:55:02 AM

Code:
two=2
trace=service.tra
while [ $two != 0 ]
do
cd /home/linus
find . -name "service.tra"
size=$(du -sk $trace |awk '{print $1}')
if [ $size -gt 3000 ]
   then
      cat $trace > temp1
      mv temp1 /home/linus/gaurav
       rm $trace
       $one = `expr $one + 1`
    else
      echo "size is less than 3 MB"
fi
done


this is what i try to achieve. I want to run this script infinitely, check if the trace file is generated, if it is generated, calculate its size and then move it to other folder and remove it.

this trace file will be generated regularly and if we do not remove it then its size will increase

problem i am facing is that i am not able to check if file is present in that folder

TRACE-CMD-STOP(1)														 TRACE-CMD-STOP(1)

NAME
trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing to the ring buffer. SYNOPSIS
trace-cmd stop DESCRIPTION
The trace-cmd(1) stop is a complement to trace-cmd-start(1). This will disable Ftrace from writing to the ring buffer. This does not stop the overhead that the tracing may incur. Only the updating of the ring buffer is disabled, the Ftrace tracing may still be inducing overhead. After stopping the trace, the trace-cmd-extract(1) may strip out the data from the ring buffer and create a trace.dat file. The Ftrace pseudo file system may also be examined. To disable the tracing completely to remove the overhead it causes, use trace-cmd-reset(1). But after a reset is performed, the data that has been recorded is lost. SEE ALSO
trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1), trace-cmd-list(1), trace-cmd-listen(1) AUTHOR
