Is there a way to define an unlimited history in Bash ?
View 3 Replies View RelatedHow can I get/filter history entries in a specific range?I have a large history file and frequently usehistory | grep somecommandNow, my memory is pretty bad and I also want to see what else I did around the time I entered the command.For now I do this:get match, say 4992 somecommand, then I do history | grep 49[0-9][0-9]this is usually good enough, but I would much rather do it more precisely, that is see commands from 4972 to 5012, that is 20 commands before and 20 after. I am wondering if there is an easier way? I suspect, a custom script is in order, but perhaps someone else has done something similar before.

View 3 Replies View RelatedHow is shell history specific to each tty? I can't see anything in the history files that would indicate which tty a command was performed on, however if I restart and log in on several ttys, the command order and history is preserved on each. How is this accomplished? This goes for zsh and bash equally.Now for some zsh specific questions.I had a saved webpae, which resulted in a file called doku.php.htm, and a directory called doku.php_files - I could only get zsh to expand the directory. It didnt seem to give me the option to cycle nor did it only complete as much as it could with ambiguity, i.e. to doku.php , so what is this behaviour and where can I read about it?
Secondly I would like to know why zsh interactive shells do not expand the PS1 prompt completely. Whenever I open an xterm or such, the prompt is not the normal PS1 prompt. I read through the manuals and config files, and could see nowhere that staed a different prompt should be used depending on the shell type. Why does this happen, and how can I modify this behavior?Regarding modules, if I install the compat-wifi modules which I assume replace the existing ones, how would I uninstall them? Would I just reinstall the normal kernel modules over them?

View 3 Replies View RelatedI would like to keep track of not only what bash commands I used and when, but also where they were issued from, i.e. what was the current working directory when I issued "foobar" on a particular day and time. Can we ask bash history to keep track of working directories too? I have tried to get an idea of this reading the enormous "man bash", but I don't seem to have an answer yet either way.

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

installed Ubuntu Server Edition and I've found that my first user has a bash history and I can turn on a coloured prompt by editing my .bashrc etc but new users don't have that!I did : useradd -d /home/newb -m newbpasswd newband the correct looking .bashrc file appears to be in /home/newb but it is being ignore by bash when logged in as newb. Instead I am presented with just a dollar prompt instead of "newb@server"how can I sort out my users with proper prompts?

Ubuntu :: save copy of bash entries / history?
View 7 Replies View RelatedI've been looking for how to set this up in bash with no luck so far. I can change what file the history log is written to, and how much history is saved. But it only writes the saved part when bash exits. Instead, I'd like to have bash write that file continuously as each command is entered (and maybe also do an fsync(2) to flush it to disk). That way I can see the command I crashed the box with Anyone know the magical incantation for that?
But there appears to be nothing that I can find there, in the man page, or other searches, that suggest it even can do continuous.
Currently the terminal prompt looks like this:[karlis@karlis-desktop current_folder]$How can I minimize the prompt, so that it only shows $ or # without extra info in square brackets?I checked the preferences for the default Gnome-Terminal and Terminator - there are no settings for this. It is pretty hard to use terminal when working in directories with long names.
