I have the following command that I'm trying to tweak:
stat -c %y test.txt | sed 's/^\([0-9\-]*\)/\1/'
This returns the following information:
I need to tweak this so that it excludes the ".000000000". I've tried a few different options but can't seem to get it right. Ultimately, I need to take the time stamp that I extract from the above command, and echo it as the first line into the file.
I have this command as an example that seems to correctly add a new line to the top of the file:
sed -i '1s/^/this should be a date\n/' test.txt
How do I combine the two commands?
