Hi All,
I have a unix old script i but i am not able to understand the few commands in it and what it does. below is the script.
Code:
 if [ -f /ITF_*.dat ];
  then 
     for F in $(find $DIR/. ! -name . -prune -name "DP_*.dat")  
    do
     IN=${F##/*/}
     OUT='ORD'$(echo $IN | cut -c7-)
    exec.ksh $IN $OUT
     if [ $? -ne 0 ]; then
       exit 1
     fi
   done

I am not able to understand what does this script code part does and also what does the below command does.
1. if [ -f /ITF_*.dat ];
2. IN=${F##/*/}
