I have been very busy last week and specially yesterday with 20 hours of continueous work, but managed to get this working :).

When you right click on Xterm with Ctrl pressed, there pops up a menu for selecting the size of the font. I have always wondered how to set this as default font and/or use this from the command line. So I searched my old homedir and looked for few of the docs that I had to get the information. Here is what I found.

Jokes – many to be downloaded once..

All work and no fun makes Jack dull boy. So lets do something for fun. Here is a one liner I wrote sometime back.  The original idea is not mine and I don&#8217;t remeber where I got the idea from but it was some other one liner that I was browsing for some oracle query. Anyway here&#8217;s the one liner to get lot of jokes in one file.

Bash completion error — quote_readline.

There is a problem with bash completion with quote_readline that causes the completion to fail. The problem is fixed in the bash completion package but there are still some other programs which are using the problematic code. Here is a way to find and resolve it.

First find the problematic program, most likely the recent one after which you started having the problems. Once that is found, find the file containing the definition of the function &#8221;_filedirs()&#8221;. Now, delete this file and create a symbolic link to the bash_completion file in the /etc directory. If this file is not present then you need to install the bashcompletion package.
