I would like to detect when the transfer of a large amount of files is completed. I would like to accomplish this by detecting the size of the folder with a time delay.
Below is what I have done,
#!/bin/bash
firstSize= du -s /Users/test/Desktop/folder | cut -f1
sleep 3
newSize= du -s /Users/test/Desktop/folder | cut -f1
until [ $firstSize -eq $newSize ]
do
firstSize=$newSize
sleep 3
newSize= du -s /Users/test/Desktop/folder | cut -f1
done
echo 'Done'
The until loop is not working because even when the firstSize and the newSize are not equal the loop completes. I am not familiar with writing Bash scripts so I am just making mistakes. This loop is ported over from an applescript I had wrote for the same purpose but I need something more reliable.
Answer
You messed the commands syntax. The script should look like:
#!/bin/sh -
firstSize=$(du -s /Users/test/Desktop/folder | cut -f1)
until
sleep 3
newSize=$(du -s /Users/test/Desktop/folder | cut -f1)
[ "$firstSize" -eq "$newSize" ]
do
firstSize=$newSize
done
echo 'Done'
