  • Remove color codes (special characters) with sed

    This command builds upon some of the original commands posted here. Additions - The control sequence \x1b(B which selects the default character set ASCII. - Either the \x1B style escape sequence or the \033. - Case insensitivity by using 'I' to include \x1b, \x1B escapes and a-zA-Z in the latter part Tested extensively on makefile unbuffered output where the above additions proved necessary

Get the time from NIST.GOV

Recursive search and replace (with bash only)

Alias to securely run X from tty and close that tty afterwards.
There are different ways to run X, I prefer to run it without xdm/gdm. The problem is you can't lock X because one can press Ctrl+Alt+F1, press Ctrl+Z and kill you X locking process. Of course you can disable Ctrl+Alt* or Ctrl+Alt+Backspace keys, but it's inconvinient if you really need to switch into console.

Real time duplication of Apache app traffic to a second server
This takes the stream created by apache requests containing jsp and funnels them to another server. I'm using this for simulating real time traffic. The nice command gives ssh maximum CPU cycles, awk & grep strip out everything served by apache. Putting parallel on curl is important because curl is synchronous and waits for the response. Yes, I thought about using wget but it didn't seem any easier. Also, if you figure out how to run this in the background let me know. Every time I background it it stops. If you have multiple front end servers just run multiple instances of this.

Google URL shortener
