Offer help at the bash command prompt. Al Williams

. bashelp.sh

Near the start of the file is a line:

bind -x '"\C-Y":_bash_help'

You can change the key from Ctrl + Y to something else by changing this line and sourcing the file again.

The way that bashelp shows man pages can be configured through environment variables, without modifying the script itself. The default settings, shown below, tell bashelp to run man in an xterm:

BASHELP_MANPGM=man
BASHELP_TERMINAL=xterm
BASHELP_USEBROWSER=0

Supported values for BASHELP_TERMINAL are:

• man (runs man in the current terminal)
• screen (shows man pages in a new window of GNU Screen)
• tmux (shows man pages in a new window of tmux)
• gnome-terminal
• Any terminal that takes the same command-line options as xterm

Graphical terminals can be passed additional options using BASHELP_TERMOPT.

Or, you can run a GUI man reader like yelp by setting:

BASHELP_MANPGM="yelp"
BASHELP_PREFIX="man:"
BASHELP_TERMINAL=
BASHELP_USEBROWSER=0

Or, you can open a web site using the default web browser by setting:

BASHELP_USEBROWSER=1
BASHELP_SITE="http://man.he.net/?section=all&topic=" #(or equivalent)

Or, you can open a local man page in a browser by setting:

BASHELP_MANPGM=man
BASHELP_USEBROWSER=1
BASHELP_SITE=
BASHELP_MANOPT="-H "
BROWSER=google-chrome
