Pipeing linux commands and their output

As a system administrator, I always worry about certain things, like who's doing what, what processes are running, what the network traffic looks like, etc.  One day I decided to create a simple alias that would combine all the commands I wanted into one big chunk of information.  Then I realized that it wouldn't all fit into one screen.
Fortunately I knew how to group all of the commands together, so the "more" command could handle them as one set of input.

Change phpMyadmin theme.

Changing the phpMyAdmin theme is as easy as downloading a theme from <a href="http://www.phpmyadmin.net/home_page/themes.php" target="_blank">here. Then look at your /etc/httpd/conf.d/phpMyAdmin.conf file and check the line similar to

Alias /phpMyAdmin /phpMyAdmin

The second path is the path to your phpMyAdmin installation. Go to that directory and then go to themes directory and unzip the file. Reload your phpMyAdmin page in browser and select the newly installed theme 🙂

View the newest xkcd comic.

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

$ xkcd(){ local f=$(curl -s <a href="http://xkcd.com/">http://xkcd.com/);display $(echo "$f"|grep -Po '(?<=")http://imgs.xkcd.com/comics/[^"]+(png|jpg)');echo "$f"|awk '/<img src="http://imgs.xkcd.com/comics/.?" title=./{gsub(/^.title=.|".?$/,"");print}';}

To get a random xkcd comic, I also use the following:

xkcdrandom(){ local f=$(wget -q <a href="http://dynamic.xkcd.com/comic/random/">http://dynamic.xkcd.com/comic/random/ -O -);display $(echo "$f"|grep -Po '(?<=")http://imgs.xkcd.com/comics/[^"]+(png|jpg)');echo "$f"|awk '/<img src="http://imgs.xkcd.com/comics/.?" title=./{gsub(/^.title=.|".?$/,"");print}';}

$ ls -alh #mycomment

Comments can be used directly on the command line so I can save in the history a brief description of what command does.
