Urgent Help: About Bash scripts...

[amin]

Hi all, I'm a bit familiar to bash script, but I am not experienced enough to solve this problem:
I wanna to modify last record of Cardregistery as below:

Directory = ekonsole 

I wanna change it to:

Directory = /mmc/mmca1/.system/QTDownLoad/ekonsole 

(just in the last record)
anybody can help me, please?

Try this? It might a little slower...

n=1;
g=0;
finish=0;
declare -a dir;
declare -a line;
while test "$finish" != "1"; do
  get=`sed -n ${n}p $file`; # $file is ur card registry
  if test $(echo $get|grep "Directory = "); then
    let g++;
    dir[$g]=`echo $get|sed "s/Directory = //"`;
    line[$g]=$n;
  elif test ! "$get"; then
    finish=1;
  fi
  let n++
done
## modify the last records, $g is the latest...
sed -e "${line[g]}s:Directory = ${dir[g]}:Directory = $new_dir:" $file > /tmp/temp.txt; # the $new_dir is the new directory u wanted to replace
if cat /tmp/temp.txt; then
  mv /tmp/temp.txt $file;
fi
## try to avoid an error
## done

Just for note...i havent tried this code yet...if u want to test, use a copy of card registry...
In this code, we read the entire card registry...then assign it to array... So u can modify any Directory by number order... However, if u just want edit the "Directory = ekonsole" to "Directory = /mmc/mmca1/.system/QTDownLoad/ekonsole" just use sed...

Why do you want to change it? My CardRegistry has Directory = ekonsole
