title: Using timestamp of a particular command in bash script?
body: <p>I'm trying to use the timestamps of a particular command I ran previously. Running something along the lines of <code>history 10 | grep "keyword"</code> gives me the output in the command line (my history preferences are set up to include a timestamps), but I can't actually figure out how to utilize this information in a script.  </p>
  
  <p>Is there any way to use this or another way to get the timestamps from a particular command? I'm trying to determine the last time a <code>command</code> was run, and if it was longer than a specific amount of time, run it again.</p>
