Terminal history with multiple tabs - how to save all

cilbuper · 06-12-2015, 01:28 AM

I often have multiple terminal windows open and some with multiple tabs. I'm running BASH. I've found that I'll run a command in a tab and after reboot it is not in my history (and it is often a command I randomly had success with and badly need to duplicate).

So what I need to do is figure out a way to save the commands in a central repository or to separate files maybe timestamped. IDK what is possible with this.

Any suggestions on how to deal with this problem are appreciated!

Put this in somewhere /etc/profile and/or /etc/bashrc:

Code:

shopt -s histappend

And reboot. For more info 'man bash'.

Why not setup 'aliases' in your '~/.bashrc'? That way you will have the commands available via 'alias'. I like to provide my users with this;

Code:

sample '~/ .bash_profile';   
~$ cat .bash_profile 
#-----------------cut-----------------   
# .bash_profile
#08-30-06 12:21

# Source .bashrc
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

#-----------------cut end--------------

Code:

 sample ~/.bashrc
cat ~/.bashrc
#-----------------cut-------------------

#.bashrc
#08-30-06 12:20 

# Add bin to path
export PATH="$PATH:$HOME/bin"

# Dynamic resizing
shopt -s checkwinsize
#
#save bash history so as to share

shopt -s histappend
PROMPT_COMMAND='history -a'

# Custom prompt 
#PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' 
#08-29-06 11:40 gws 
if [ `id -un` = root ]; then 
 PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] ' 
else
PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] ' 
fi 
# 
# Add color 
eval `dircolors -b` 
#Terminus is a very nice Unicode font for the Linux console
#02-02-12 gws
#from dugan's site http://duganchen.ca/writings/slackware/fonts/

#04-30-12 11:41 removed
#
#if [ $TERM = "linux" ]; then
# setfont ter-v16n
#fi

# User defined aliases
alias cls='clear'
alias clls='clear; ls'
alias ll='ls -l'
alias lsa='ls -A'
alias lsg='ls | grep'
alias lsp='ls -1 /var/log/packages/ > package-list'
alias na='nano'
alias web='links -g -download-dir ~/ www.google.com'

#08-29-06 11:50

#To clean up and cover your tracks once you log off
#Depending on your version of BASH, you might have to use
# the other form of this command
 trap "rm -f ~$LOGNAME/.bash_history" 0

#The older KSH-style form
#trap 0 rm -f ~$LOGNAME/.bash_history


#-----------------cut end--------------

Hope this helps.
Have fun & enjoy!

A reboot of what, exactly? Your machine?
Are you exiting these shells or just typing

Code:

reboot

or

Code:

shutdown -r now

in one of the opened tabs?

if by history you mean using the up and down arrows, i have that problem too, and i'd like to understand/solve it.

however, these commands are still accessible with the "history" command.
i have this alias:

Code:

alias hf='history|grep'
