Some of my favorite bash tricks

Nice bash shortcuts

Some of my favorite bash tricks (most of these come straight from Emacs):

Of course, most of these will ONLY work when 'set -o emacs'
	
C-F Move to next character
C-B Move to previous character
C-A Jump to beginning of line (bol)
C-E Jump to end of line (eol)
M-B Jump to previous word
M-F Jump to next word
C-/ Undo
C-X C-X Swap point. There are two marks. You can move around, C-X C-X, move
		some more, and then switch between points.
C-X C-E Edit command in $EDITOR

C-K Kill line from point to eol
C-U Kill line from point to bol
M-D Kill next word
M-Backspace Kill previous word
C-W Kill previous word (to previous space)
C-H Kill previous character (doesn't go into kill ring)
C-D Kill next character (doesn't go into kill ring)
C-Y Yank killed text

C-R Recall text backward
C-S Recall text forward (might not work depending on terminal settings. It
		could stop flow. If this happens, C-Q restores it)

In .bashrc (or .bash_profile, .profile, etc.), I like to add
"$(parse_git_branch)$(parse_svn_revision)$(parse_cvs_tag)" to PS1 and define

parse_cvs_tag()
{
    [[ -d "CVS" ]] && ([[ -e "CVS/Tag" ]] && sed -e 's/^T/ (/' -e 's/^N/ (/' -e 's/^D/ Date /' -e 's/$/)/' CVS/Tag || echo ' (HEAD)')
}

parse_git_branch()
{
    local DIRTY STATUS
    STATUS=$(git status 2>/dev/null)
    [ $? -eq 128 ] && return
    [[ "$STATUS" == *'working directory clean'* ]] || DIRTY=' *'
    echo " ($(git branch 2>/dev/null | sed -e '/^[^*]/d' -e 's/* //')$DIRTY)"
}

parse_svn_revision()
{   
    local REV=$(svnversion 2>/dev/null)
    [ $? -eq 0 ] || return
    [ "$REV" == 'exported' ] && return
    echo " ($REV)"
}

Note: for some big repositories, this PS1 format might slow things down a bit. Use at your own risk :)
