I use TextMate on Mac OSX Mountain Lion to write notes. One thing I find myself needing a bunch is to insert the current date and time so I can track specific events. For instance if I am writing an article for Question-Defense.com and I am doing the initial formatting in TextMate, which is a typical scenario for me, I might take ten screenshots and I like to note the current date/time in case I get pulled away from the article writing for something else. So having a keyboard shortcut that outputs the current date/time is really valuable so I don’t have to type it out by hand. Below I describe how to install a OSX Service that will provide various date/time outputs via Keyboard Shortcuts. The OSX Service called WordService also provides a bunch of extra awesome services which I briefly touch on below as well.
Ever attempt to delete the Trash on OSX and run into an error that says you can’t complete the operation because you don’t have permissions to access some of the items? I am not sure how often this will happen to the average user that wouldn’t already know how to resolve the problem since the chances are high that the file or files created with different permissions required you to change to the root user in the first place. Anyhow below is a better description of the issue along with a screenshot followed by how to resolve the problem emptying your Trash on your Mac.
Earlier tonight I created a little script that will run in cron on a Linux server. The script counts the number of directories and files in a specific directory and if the count is above Y then it deletes directories and files older than X number of days. In the example script below the number of items (directories and files) that have to be located in the directory before the script to delete files older than a specific date is 10. If there are ten items then the script will delete items older than 90 days. Below the script is the entry made in a specific users cron on the Linux server.
It can be useful on a Linux server to sort all of the files in a directory by date. Sometimes you may want to backup files older than a certain date or you may just want to see what is in a directory and what date those files were created. Use the information below to list all of the files in a directory sorted by date.
