Comments on: How Not to Use Shell Commands http://www.pythian.com/news/525/how-not-to-use-shell-commands/ News and views from Pythian DBAs Fri, 10 Feb 2012 13:01:25 +0000 hourly 1 http://wordpress.org/?v=3.0.4 By: SimonH http://www.pythian.com/news/525/how-not-to-use-shell-commands/#comment-66967 SimonH Sun, 24 Jun 2007 10:16:12 +0000 http://www.pythian.com/blogs/525/how-not-to-use-shell-commands#comment-66967 A useful post - worth thinking through why the commands went wrong (might make a good opening question for a technical interview). My worst example of this was once: $ mv bigfile1 bigfile2 stage where bigfile1 and bigfile2 had taken all night to download over a 56k modem and the stage directory doesn't exist. Since then I have always put a / on the end of the directory name, though fortunately I don't think modern Unixes let you make this mistake (I've just tried Solaris10 and it says "mv: stage not found").
