Top Forums UNIX for Dummies Questions & Answers File being used/written Post 8517 by sanjay92 on Friday 12th of October 2001 04:53:59 PM

Code:
#!/bin/ksh

x=`cksum File_Name.exp | awk '{print $1}'`
#sleep 1
y=`cksum File_Name | awk '{print $1}'`
if [  $x = $y ] ; then
  echo "Both are same" $x $y
else
  echo "Both are different" $x $y
fi

This method will work to find out, if the file is still being written by comparing the two snapshots of checksum of file.

Is there any other good method ?

Thanks for taking your time.
