df -h if freespace equals then bash

0 votes

The error that I am getting is with the df command on mac, I would like to specify a value in gigabytes and perhaps allow the user to choose a different drive if / is full.

destination="$HOME/Desktop/sandbox"

if [ $(df -h --output=avail /|tail -n1) -lt 300000 ]; then

    echo "There is less than 300GB available..." ;
    exit

else

    for files in *.tar ; do echo copying "$files" ; cp "$files" "$destination" ; read -n 1 -p "Press any key..." ; done
fi

Not sure if df -h / | tail -1 | awk '{print $4}' | sed 's/..$//' is a good option

Try this out:

destination="$HOME/Desktop/sandbox"

freespace="$(df -h / | tail -1 | awk '{print $4}' | sed 's/..$//')"

if  [ "$freespace" -lt 300 ]; then

    echo "There is less than 300GB available..." ;
    exit

else

    for files in *.sh ; do echo copying "$files" ; cp "$files" "$destination" ; read -n 1 -p "Press any key..." ; done
fi
