# .kshenv -- functions and aliases to provide the beginnings of a ksh
# environment for bash.

# Chet Ramey

#
# These are definitions for the ksh compiled-in `exported aliases'. There
# are others, but we already have substitutes for them: "history", "type",
# and "hash".

alias r="fc -e -"
alias functions="typeset -f"
alias integer="typeset -i"
alias nohup="nohup "
alias true=":"
alias false="let 0"
#
# An almost-ksh compatible `whence' command. This is as hairy as it is
# because of the desire to exactly mimic ksh (whose behavior was determined
# empirically).
#
# This depends somewhat on knowing the format of the output of the bash
# `builtin type' command.
