Provide more CLI commands

[erikw]

Hi, first off, thanks for a fantastic tool, I've used it with great joy for some 1-2 years!

Many many years ago, like 10-13 or so, I started using bashmarks which provide some very neat one-letter shell commands like g mark, s mark etc.

Through the years I've used different shell bookmarks tools like jump & cd-bookmark and I've always kept the original bashmark-style commands by creating similar aliases to the other bookmarking tools, as they are so convenient!

fzf-marks stared a new area of bookmarking, with the interactive menu. When searching for a bookmark I don't know the exact name of, the the fzf interactive menu is perfect! When I know the exact name, it's often easier and faster to use a direct command.

Thus I've used aliases & functions also with fzf-marks, in the style of Bashmarks. This is what I have in my shell startup file:

alias g='fzm'                   # Jump to mark (provided as argument)
alias s='mark'                  # Save current dir as mark (provided as argument)
alias e="vi $FZF_MARKS_FILE"    # Edit bookmarks file. 
alias l="sort $FZF_MARKS_FILE"  # List all bookmarks

_fzf_marks_delete() {
  local mark="$1"
  
  if ! grep -q "^$mark : " $FZF_MARKS_FILE; then
	  echo "$mark is not in the bookmarks" >&2
	  return 2
  fi
  sed -i.bak -e "/^${mark} : /d" "$FZF_MARKS_FILE" && rm "$FZF_MARKS_FILE.bak"
}
alias d='_fzf_marks_delete'  # Delete mark (provided as arg)

_fzf_marks_print() {
  local mark="$1"
  
  if ! grep -q "^$mark : " $FZF_MARKS_FILE; then
	  echo "$mark is not in the bookmarks" >&2
	  return 2
  fi
	  grep "^$mark :" $FZF_MARKS_FILE | awk '{print $3}'
  }
alias p='_fzf_marks_print'  # Print a mark (provided as arg)

This works, but it would be neat if there was built-in support by this tool to do operations like edit, list and delete a mark!

Note: I'm not requesting that this tool should adopt the bashmark-style command names like g, s etc., that I can always create myself, but a requst to provide some switches or subcommands to fzfm or mark to do this. Maybe mark -d abookmark could delete a bookmark named abookmark for example.
