Thanks for suggestions or links.


look for 'command line editing in bash'  The default mode is emacs style 
controls for moving through history and on a line to insert and delete. 
There is also a 'vi' mode set up by entering 'set -o vi' that does the 
same thing.

I use the following in bashrc

if [ "$PS1" ]; then 
 
  bind '"\e[A"':history-search-backward 
 
  bind '"\e[B"':history-search-forward  
 
  bind '"\e[23~"':"\"\C-k\C-ahistory | grep '^ *[0-9]* *\C-e.'\C-m\""   
 
  bind '"\e[24~"':kill-whole-line   
 
  bind Space:magic-space
 
  shopt -s histappend   
 
  export PROMPT_COMMAND='history -a'
 
if

This privides the same functionality you mentioned for windows plus: F12 erases 
the current command line without executing it, F11 will show the entire history 
of commands that start with any character typed on the command line before 
pressing F11.

The shopt part is supposed to insure that each new command line executed is 
saved immediately in the history file, instead of when the shell is closed.

Yes, everyone, I know about grep. :-)

In addition to keyboard shortcuts...

history | grep abc | less

If what you're looking for came from a different, now closed, terminal
window, try

grep $HISTFILE abc | less

I have this snippet in my .bashrc that binds the up and down keys to search
for the commands starting with the characters that you type in, so if you
type "ls" and press the up key, it will bring up the last command that
started with ls

if [[ $- == *i* ]]
then
  bind '"\e[A": history-search-backward'
  bind '"\e[B": history-search-forward'
fi

control-R is bound to reverse-search-history by default.  That will
search anywhere in previous commands, so for example typing "s" followed
by ^R would show matches for "ls".

If instead you want to search for commands with the same start (so just
typing "s" would only show commands that started with "s"), you want
history-search-backward, which is bound to PageUp on Fedora (not bound
by default upstream IIRC).

$ history | grep "abc"

But you will have different histories per virtual terminal I think...

Uh, the history command?  history | grep 

Or there's the UP arrow in the terminal. Does what that DOS tool did.

looking for a BASH tool

2016-06-27 Thread SternData 
Years ago, I used a tool called CED and PCED on DOS systems.  I could
type in "abc" and press an up-arrow and it would walk back through my
stack of DOS commands showing only those with "abc" in them.

There's *got* to be a similar tool for bash, but my google-fu is weak today.

Thanks for suggestions or links.
