1. System beeps: Sick of those system beeps.Well then tell them to shut up.Here is the command. Type in the command setterm -blength 0 in the terminal.You will no longer hear a beep in that session. If you dont want to type it all the time, then add it to the system startup as mentioned in trivia#2. Have some peace of mind.
2.Command History: As you all know command history is a handy tool when using a terminal. But sometimes you will notice that the command u are looking for is already gone from the history.Well, to avoid it, you better set the size of the history archive by putting the following in the .bashrc file:
HISTSIZE=999
HISTFILESIZE=999
Oh,if that looks like a too big archive to search for a command,then u can always make use of grep. The command will be like:
history | grep -i str
where str is a part of the command u are looking for. So no more forgotten commands in your life.
PS: You can unset the value of HISTSIZE and HISTFILESIZE to permenantly keep a history of all commands ever used, but its not recommended for obvious reasons.
