# About
Shell History Cleaner is a simple program that cleans the bash/shell history for you.
Shell history is the commands that you see when pressing `Up` or `Ctrl R` (to search) in the terminal.
# Use
Install Rust/cargo. After that:
```sh
cargo install --force shell-history-cleaner
shell-history-cleaner --dedup "$HISTFILE" # remove duplicates
shell-history-cleaner --dedup --remove 'youtube-dl .*' "$HISTFILE" # also remove video downloads
```
# Help
```
USAGE:
shell-history-cleaner [OPTIONS] <TARGET_FILE>
ARGS:
<TARGET_FILE>
Target file to clean. You can use "$HISTFILE" to clean up the shell history.
OPTIONS:
-d, --dedup
De-duplicate lines to only keep one last occurrence of each dup.
-r, --remove <REMOVE>
Lines to remove. For example, 'yt-dlp.*' will remove lines starting with 'yt-dlp'.

Another real-life example:
'(ps aux.*|git checkout .*|git branch .*| .*|yt-dlp .*|chmod .*|echo .*|man .*)'

This program loads the file contents in memory. Don't use this script if your history file is 1Gb (hope not it's not though:)
