linux - Use compgen to get autocomplete for another command, which flag to use? -

-

i have custom auto-completed command (call commanda)

in commandb want steal autocomplete options first argument commanda

so, example options argument1 commanda are:

abcdef abcabc abc123

i along lines of compgen -? "commanda" or compgen -? "commanda abc" generate list above.

you can use complete -p commanda find out function invoked custom completion command. (you need argument -f option. if there other optiond, becomes more complicated.)

you need set standard completion environment variables (whose names start comp_) , call function appropiate arguments. fill in compreply variable; if necessary, add other possibilities. see bash manual details.
