symbolic link on folder created every day

Question

I've this structure

• 2011-04-18T07.32.19UTC
• 2011-04-19T07.32.19UTC
• 2011-04-20T03.15.01UTC

Every night, a new directory based on the current date is created.
I would create a symbolic link on the latest directory created:

mysimlink --> 2011-04-20T03.15.01UTC

But tomorrow I would see

mysimlink --> 2011-04-21T03.15.01UTC

How can I do it?

Answer 1

You need to write a script which will removes the existing symlink and then creates a new symlink pointing at the directory with today's date. Here is some code:

today=$(date +%Y-%m-%d)

# find today's directory
todayDir=$(ls -d $today*)

# if the directory exists
if [ -d $todayDir ]
then
    rm -f mysymlink
    ln -s $todayDir mysymlink
fi
