cycle through reverse search in a custom command history file in bash
Clash Royale CLAN TAG#URR8PPP
1
I added a line to ~/.bashrc file which appends all issued commands to ~/.bash_eternal_history file in a date directory history-number command format, such as:
2019-01-08.23:59:32 /home/sport/Desktop 745 pwd
I need a reverse-i-search feature to bring up commands from my custom history file ~/.bash_eternal_history searching key words and cycle through each result one by one using up or down keys
How can I achieve that?
bash awk grep command-history bash-functions

This, from man bash:
HISTFILE
The name of the file in which command history is saved (see HISTORY below). The default value is
~/.bash_history. If unset, the command history is not saved when a shell exits.
HISTFILESIZE
The maximum number of lines contained in the history file. When this variable is assigned a value,
the history file is truncated, if necessary, to contain no more than that number of lines by remov‐
ing the oldest entries. The history file is also truncated to this size after writing it when a
shell exits. If the value is 0, the history file is truncated to zero size. Non-numeric values
and numeric values less than zero inhibit truncation. The shell sets the default value to the
value of HISTSIZE after reading any startup files.

Thank you for your answer. I didn't know that trick, I can use it as a last resort. But I thought of someawk,grep,sedetc. functions triggered byupordownkeys.
