I use the following binding to allow me to press Control-Z to resume a program I previously backgrounded. I set histoptignorespace and put a space in front of fg so the command doesn't persist in my history.
However, it still appears when I press the up arrow. Any way to remove this as well? I would like pressing the up arrow to ignore the fact that fg was ever entered.
# Allow Ctrl-z to toggle between suspend and resume
function Resume {
zle push-input
BUFFER=" fg"
zle accept-line
}
zle -N Resume
bindkey "^Z" Resume
The following worked for me. It really just runs fg directly. The rest is necessary to get back to the prompt.
# Allow Ctrl-z to toggle between suspend and resume
function Resume {
fg
zle push-input
BUFFER=""
zle accept-line
}
zle -N Resume
bindkey "^Z" Resume
