'have' keyword for bash completion

Question

Is have a keyword in bash? Or do bash completion scripts use a language that is not bash?

have gcc &&
_gcc()
{

It is commo

Answer 1

have and _have are just two functions defined in the base bash_completion file. Between the two, they form a wrapper around the built-in type command to determine if a particular command/program available.

# This function checks whether we have a given program on the system.
#
_have()
{
    # Completions for system administrator commands are installed as well in
    # case completion is attempted via `sudo command ...'.
    PATH=$PATH:/usr/sbin:/sbin:/usr/local/sbin type $1 &>/dev/null
}

# Backwards compatibility for compat completions that use have().
# @deprecated should no longer be used; generally not needed with dynamically
#             loaded completions, and _have is suitable for runtime use.
have()
{
    unset -v have
    _have $1 && have=yes
}
