Viewing “man” Pages in a Web Browser
on September 16, 2011 – 12:43 am 4 Comments
The Unix “man” pages are an indispensable resource even for the most experienced of sysadmins. Unfortunately, in a terminal window the text may be hard to read and getting a hard copy to take with you down to the datacenter will really test your Unix skills. The following quick script will convert the “man” page of your choice into formatted text and open it in the Web browser.
To use this script, save it in a common binary location, such as /usr/local/bin/gman, and make it executable: chmod 755 /usr/local/bin/gman
#!/bin/bash
# www.krazyworks.com
# The script will display man page in Web browser
trap ctrl_c INT
manpage=""
configure() {
# your UID
uid=$(id | awk -F'=' '{print $2}' | awk -F'(' '{print $1}')
# Web browser executable
wbrowser="/usr/bin/firefox"
# file for storing PID of the Web browser
pid="/tmp/gman_browser${uid}.pid"
# temporary file for storing HTML version of man page
gmantemp="/tmp/gman_temp_${uid}_${manpage}"
}
cleanup() {
# cleanup old files
for i in "${pid}" "${gmantemp}"
do
if [ -f "${i}" ]
then
/bin/rm -f "${i}"
fi
done
}
function gman {
man "${manpage}" | col -b > "${gmantemp}"
/usr/bin/firefox "${gmantemp}"
}
function ctrl_c() {
cleanup
exit 1
}
configure
cleanup
gman
cleanup

I have my CDA. I have many years of experience with young children. In the near future I would like to open a daycare. I would like to hopefully get some helpfull hints on running the business side, so I can become better prepared. What are some things that you wish were told to you before you opened a daycare to help you become better prepared? Any other suggestions would be appreciated.
Earth, air, fire and water, viewed as sacred and indispensable, can be seen as an approach to also living in ways that show virtue and respect to those elements. How do neopagans view and react to living in culture forms that are categorically environmentally unsustainable? Do many have views against centralized government and excessively interdependent infrastructures? Can infrastructures such as these be seen as a form of an alienation from having an engaged, direct and immanent relationship with those resources. Are there neopagan arguments for autonomous and self sustained forms of community?
I can’t really afford a voice-coach, but I’m serious about wanting to perform as a singer (mostly country/folk). It would be so much easier if a program were intelligently mapped out for me (how much of what to do when) Does anyone with knowledge in the field know a really good book I could use for this purpose?
I was wondering how man..(through many years of course) created a device such as a computer, I mean..not the parts but how out of like an enviorment full of resources….do they come up with this electric device that can type letters , i mean what do they physically do to make this computer recognize letters…..its just a curiosity…And not only for computers but for other devices such as cameras..etc…
