.bashrc

alias cls=clear
alias dangcom='git fsck --no-progress --no-reflogs | grep '\''dangling commit'\'''
# alias dangcom='gitk --all --date-order '$(git fsck --no-progress --no-reflogs | \grep 'dangling commit' | \gawk '{printf $3; printf " "}')''
alias uptag='git show-ref --tags -s -d | grep 'refs' > list-of-tags.txt'

The drawback of this alias is that it gets expanded on shell starts - so, if a new dangling commit was created after the shell started, a new shell must be opened to get the full list of dangling commits.
