script to compress multiple files

rated 0 times [ 4] [ 0] / answers: 1 / hits: 4418 / 1 Year ago, sun, march 12, 2023, 8:00:41

I have a script that generates backup and finds files older than 30 days and compresses them. Now the problem I'm facing is if the files are more than one than how can I edit the script so that it compresses all those files as well. Below is the find function Im using. Please Help.

Time=+30

PATH_TO_DUMP=/home/tarun/Desktop/Backup



#Find any Backup File defined by the time constraint

file="$(find $PATH_TO_DUMP -type f -mtime $Time)"



#To verify if $file is empty or has some value

if [ ! -n "$file" ]; then

echo "No Earlier Backups were found to compress" >> $PATH_TO_LOG

else

echo "Earlier Backups $file will be compressed" >> $PATH_TO_LOG

gzip $file

fi

You can do that with a minor modification

(pipe the find output into while loop doing a read)

Time=+30

PATH_TO_DUMP=/home/tarun/Desktop/Backup

#Find any Backup File defined by the time constraint



find $PATH_TO_DUMP -type f -mtime $Time | while read file

do



  #To verify if $file is empty or has some value

  if [ ! -n "$file" ]; then

    echo "No Earlier Backups were found to compress" >> $PATH_TO_LOG

  else

    echo "Earlier Backups $file will be compressed" >> $PATH_TO_LOG

    gzip "$file"

  fi



done
