Delete file

Shell Programming and Scripting
1

Hello,

I need to read files from /dest directory and delete those files that are not present in /origin directory.

i.e :

1/ Read files from /dest directory
2/ If the read files don't exist on /origin directory Then delete the read file from /dest directory

Thx,

What did you try so far? Where are you stuck?

Hmm. Why not use rsync?

...actually read to much into this as I assumed a remote server....

create a little shell script:


cd /dest

for file in * ; do

  if [[ ! -f $file ]]; then
    continue
  fi

  if [[ ! -f /origin/$file ]]; then
    echo /bin/rm $file
  fi

done

I used an echo so you can test the script without nuking things accidentally.

Once you're happy with it, pipe it to ksh to make it actually nuke the files.

ie:

test:

my_rm_script.sh

fire:

my_rm_script.sh | ksh
