Why can't I use command line editing in my `cmdtool'?
Why can't I use command line editing in my `cmdtool'?
The problem is `cmdtool' and bash fighting over the input. When
scrolling is enabled in a cmdtool window, cmdtool puts the tty in
`raw mode' to permit command-line editing using the mouse for
applications that cannot do it themselves. As a result, bash and
cmdtool each try to read keyboard input immediately, with neither
getting enough of it to be useful.
This mode also causes cmdtool to not implement many of the
terminal functions and control sequences appearing in the
`sun-cmd' termcap entry. For a more complete explanation, see
that file examples/suncmd.termcap in the bash distribution.
`xterm' is a better choice, and gets along with bash much more
smoothly.
If you must use cmdtool, you can use the termcap description in
examples/suncmd.termcap. Set the TERMCAP variable to the terminal
description contained in that file, i.e.
TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:'
Then export TERMCAP and start a new cmdtool window from that shell.
The bash command-line editing should behave better in the new
cmdtool. If this works, you can put the assignment to TERMCAP
in your bashrc file.
