Top Forums UNIX for Dummies Questions & Answers How to clear history in Linux Post 302480472 by pludi on Wednesday 15th of December 2010 03:47:34 AM

Bash keeps it's history internally until it exits. This is why your .bash_history can be empty while you see old commands. This is also the reason why, when closing multiple instances of bash (eg. terminal sessions), only the commands from the last closed session can be found again.

To completely clear, you'll have to remove .bash_history without running bash.

Devel::REPL::Plugin::ReadLineHistory(3pm)		User Contributed Perl Documentation		 Devel::REPL::Plugin::ReadLineHistory(3pm)

NAME
Devel::REPL::Plugin::ReadLineHistory - Integrate history with the facilities provided by Term::ReadLine DESCRIPTION
This plugin enables loading and saving command line history from a file as well has history expansion of previous commands using the !-syntax a la bash. By default, history expansion is enabled with this plugin when using Term::ReadLine::Gnu. That means that "loose" '!' characters will be treated as history events which may not be what you wish. To avoid this, you need to quote the '!' with '': my $var = "foo!"; or place the arguments in single quotes---but enable the "Term::ReadLine" attribute "history_quotes_inhibit_expansion": $_REPL->term->Attribs->{history_quotes_inhibit_expansion} = 1; my $var = 'foo!'; and to disable history expansion from GNU readline/history do $_REPL->term->Attribs->{do_expand} = 0; CONFLICTS
Note that Term::ReadLine::Perl does not support a history expansion method. In that case, you may wish to use the Devel::REPL History plugin which provides similar functions. Work is underway to make use of either History or ReadLineHistory consistent for expansion with either the Term::ReadLine::Gnu support or Term::ReadLine::Perl. perl v5.14.2 2010-06-13 Devel::REPL::Plugin::ReadLineHistory(3pm)
