Bookmarking directories in bash

bashmarks.sh

# Originally from: https://github.com/twerth/dotfiles
# Bashmarks is a simple set of bash functions that allows you to bookmark 
# folders in the command-line.
# 
# To install, put bashmarks.sh somewhere such as ~/bin, then source it 
# in your .bashrc file (or other bash startup file):
#   source ~/bin/bashmarks.sh
#
# To bookmark a folder, simply go to that folder, then bookmark it like so:
#   bookmark foo
#
# The bookmark will be named "foo"
#
# When you want to get back to that folder use:
#   go foo
#
# To see a list of bookmarks:
#   bookmarksshow
# 
# Tab completion works, to go to the shoobie bookmark:
#   go sho[tab]
# 
# Your bookmarks are stored in the ~/.bookmarks file

bookmarks_file=~/.bookmarks

# Create bookmarks_file it if it doesn't exist
if [[ ! -f $bookmarks_file ]]; then
  touch $bookmarks_file
fi

bookmark (){
  bookmark_name=$1

  if [[ -z $bookmark_name ]]; then
    echo 'Invalid name, please provide a name for your bookmark. For example:'
    echo '  bookmark foo'
  else
    bookmark="`pwd`|$bookmark_name" # Store the bookmark as folder|name

    if [[ -z `grep "$bookmark" $bookmarks_file` ]]; then
      echo $bookmark >> $bookmarks_file
      echo "Bookmark '$bookmark_name' saved"
    else
      echo "Bookmark already existed"
    fi
  fi
} 

# Show a list of the bookmarks
bookmarksshow (){
  cat ~/.bookmarks | awk '{ printf "%-40s%-40s%s\n",$1,$2,$3}' FS=\|
}

go(){
  bookmark_name=$1

  bookmark=`grep "|$bookmark_name$" "$bookmarks_file"`

  if [[ -z $bookmark ]]; then
    echo 'Invalid name, please provide a valid bookmark name. For example:'
    echo '  go foo'
    echo
    echo 'To bookmark a folder, go to the folder then do this (naming the bookmark 'foo'):'
    echo '  bookmark foo'
