Default Automatic dual xterm setup for log file monitoring

While testing a Apache webserver configuration, I became tired of setting up two xterms for monitoring both the /var/log/httpd-access and /var/log/httpd-error.log files.

The following simple script does this now for me:

Code:
#!/bin/sh

# Set up two xterms
#   1) tail -f /var/log/httpd-access.log
#   2) tail -f /var/log/http-error.log

ACCESS='ssh j65nko.org "tail -f /var/log/httpd-access.log"'
ERROR='ssh j65nko.org "tail -f /var/log/httpd-error.log"'

# geometry (See X(7)  'GEOMETRY SPECIFICATIONS')
# WidthxHeight+X_offset+Y_offset
# Width and Height either in pixels or characters
# X_offset and Y_offset in pixels

# See xterm(1) for the other options

xterm -geometry 200x30+0+0   -bg black -fg green -e "${ACCESS}" &
xterm -geometry 200x30+0+500 -bg black -fg red   -e "${ERROR}" &
Please note that according to the xterm manual page. the -e option for specifiying the command needs to be the last one.

This script has been tested and is being used in Debian as you can see in the trimmed screenshot.

Cool.

Too often we forget the good old -geometry command line options and X resources. People often recommend tiling or other simple window manages to eliminate the silly repetitive fiddling with window arrangements, but geometry can eliminate this with most any wm for your common cases. I recently did something similar to get to my new preferred emacs frame layout (a fixed font taking the left 3/4 of the screen for editing and a variable pitch font taking the rest for reading documentation -- okay, technically I did this with emacs settings not X settings, but same difference). This with fluxbox, but it should translate unchanged when I finally get around to replacing fluxbox with a wm I like on this machine, like cwm or stumpwm (hmm, maybe geometry won't work with stumpwm or ratpoison).

No, I was not aware that such a tool like multitail existed. There even seems to be an OpenBSD package for it
