Short cuts in HP-UX 11.00 - with question!

Simon R Wootton — Wed, 29 Aug 2001 12:56:03 GMT

I'm wanting to switch on the functionality whereby the last used commands are displayed acting as shortcuts to typing command lines in again. How do I do this ?? Pls help.

make sure you have a .sh_history file and that in your .profile you have the following:

HISTFILE=$HOME/.sh_history
export HISTFILE

Hope this helps

You need the following entries in your $HOME/.profile file (when using /usr/bin/sh, ksh or /sbin/sh as a shell):

HISTFILE=$HOME/.sh_history
export HISTFILE
set -o vi

Further to the above, you need to have your shell as /usr/bin/ksh or /usr/bin/sh.

Hi,

you can use this if you want.

set your EDITOR to "vi" if it is not already done through your profile.
EDITOR=vi
export EDITOR

then use

ksh -o vi

this will create a file .sh_history in your home directory if it is not available and will use one if it is already available. After this you can use k,l,j, and h for navigation through your earliar commands.

Hope this helps

Thanks

The command history is always enabled in the Korn shell (ksh) but must be explicitly enabled for the POSIX shell (part of the extra security found in /usr/bin/sh and /sbin/sh). Only one entry needs to be added to /etc/profile:

export HISTFILE=$HOME/.sh_history

Then logout and back in again. If .sh_history does not exist (primarily for root), you may have to create it using the touch command:

touch $HOME/.sh_history

Actually, only a single ESC is neede to recall the last command as in: ESC k

Some really useful command recall features:

Search for a particular command:
ESC / (search backwards for a string)

then after the first occurance of the search is found, use the letter n to move to the next one just like vi).

Recall a specific command:
history (that's an alias for fc -l)
or
history -100 (show the last 100 entries)

To recall a specific command:
r 123

You can edit a recalled command using most of the vi line edits and once the line is correct, press return to execute.

See the man page for sh-posix

Hello Simon,

and if you add "set -o viraw" after the
"set -o vi" you do get the Filename Completion
feature when you press after the
first few characters of a filename...

HTH,
