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:


# 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.
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
