Detailed Usage Guide

Shell Integration

BCMR provides flexible shell integration similar to zoxide. You can customize command names with prefixes or replace native commands.

Basic syntax:

bcmr init [shell] [options]

Available options:

• --cmd <prefix>: Set command prefix (e.g., 'b' creates bcp, bmv, brm)
• --no-cmd: Don't create command aliases
• --path <path>: Add directory to PATH

Examples:

# Add to your ~/.bashrc or ~/.zshrc:
# Use custom prefix (creates testcp, testmv, testrm)
eval "$(bcmr init zsh --cmd test)"

# Replace native commands (creates cp, mv, rm)
eval "$(bcmr init zsh --cmd '')"

# Use 'b' prefix (creates bcp, bmv, brm)
eval "$(bcmr init bash --cmd b)"

Supported shells:

• Bash
• Zsh
• Fish

Copy Command (Copy)

Basic syntax:

bcmr copy [OPTIONS] <SOURCES>... <DESTINATION>

Arguments:

  <SOURCES>...   Source files/directories
  <DESTINATION>  Target directory

Options:

• -r, --recursive: Recursively copy directories
• -p, --preserve: Preserve file attributes
• -f, --force: Overwrite existing files
• -y, --yes: Skip overwrite confirmation
• -e, --exclude <PATTERN>: Exclude files/directories matching regex
• -t, --tui: Use plain text mode
• -V, --verify: Verify file integrity after copy
• -C, --resume: Resume interrupted copy (Size + Mtime check)
• -s, --strict: Use strict hash verification for resume
• -a, --append: Append to existing file (ignores mtime/hash)
• -n, --dry-run: Dry run (no changes)
• -h, --help: Print help information

Examples:

# Copy a single file
bcmr copy document.txt backup/

# Copy multiple files (Shell Globbing supported!)
bcmr copy *.txt *.md backup/

# Recursively copy a directory
bcmr copy -r projects/ backup/

# Dry run (Preview what will be copied)
bcmr copy -r -n projects/ backup/

# Copy with attribute preservation
bcmr copy --preserve important.conf /etc/

# Force overwrite without prompting
bcmr copy -f -y source.txt destination.txt

# Copy with Regex exclusions (exclude .git folder and .tmp files)
bcmr copy -r --exclude="\.git","\.tmp$" src/ dest/

# Copy with verification
bcmr copy --verify critical_data.db /backup/

Move Command (Move)

Basic syntax:

bcmr move [options] <source>... <destination>

Available options:

• -r, --recursive: Recursively move directories
• -p, --preserve: Preserve file attributes
• -f, --force: Force overwrite existing files
• -y, --yes: Skip overwrite confirmation
• -n, --dry-run: Preview operation without making changes
• -e, --exclude=<pattern>: Exclude matching files (Regex)
• -t, --tui: Use plain text mode
• -V, --verify: Verify file integrity after move
• -C, --resume: Resume interrupted move (cross-device fallback only)
• -s, --strict: Use strict hash verification for resume
• -a, --append: Append to existing file (ignores mtime/hash)

Examples:

# Move a single file
bcmr move old_file.txt new_location/

# Move multiple files
bcmr move file1.txt file2.txt new_location/

# Recursively move a directory
bcmr move -r old_project/ new_location/

# Dry run
bcmr move -n old_project/ new_location/

# Move with exclusions (Regex)
bcmr move -r --exclude="^node_modules","\.log$" project/ new_place/

Remove Command (Remove)

Basic syntax:

bcmr remove [options] <path>...

Available options:

• -r, --recursive: Recursively remove directories
• -f, --force: Force removal without confirmation
• -i, --interactive: Prompt before each removal
• -v, --verbose: Show detailed removal process
• -d, --dir: Remove empty directories
• -n, --dry-run: Preview operation without making changes
• -e, --exclude=<pattern>: Exclude matching files (Regex)
• -t, --tui: Use plain text mode

Examples:

# Remove a single file
bcmr remove unnecessary.txt

# Remove multiple files (Globbing)
bcmr remove *.log

# Recursively remove a directory
bcmr remove -r old_project/

# Dry run (safe check)
bcmr remove -r -n potentially_important_folder/

# Interactive removal of multiple files
bcmr remove -i file1.txt file2.txt file3.txt

# Remove with exclusions (Regex)
bcmr remove -r --exclude="\.important$","\.backup$" trash/

Progress Display Modes

BCMR provides two progress display modes:

fancy mode (Default) and plain text mode (enable with --tui or -t).

Configuration

You can fully customize the progress bar by creating a configuration file at ~/.config/bcmr/config.toml:

[progress]
style = "fancy"          # "fancy" (default), "plain" (same as --tui)

[progress.theme]
# Define progress bar gradient (Hex colors) - Default is a Morandi purple gradient
bar_gradient = ["#CABBE9", "#7E6EAC"] 
bar_complete_char = "█"
bar_incomplete_char = "░"
text_color = "reset"     # "reset" (default), "black", "red", "green", "yellow", "blue", "magenta", "cyan", "white", or Hex "#RRGGBB"
border_color = "#9E8BCA"
title_color = "#9E8BCA"

[progress.layout]
box_style = "rounded"    # "rounded" (default), "double", "heavy", "single"
