当我在mac上打开终端时，如何摆脱“-bash：ulimit：open files”

Question

每次我打开一个新的终端，这些消息就会出现：

-bash: ulimit: open files: cannot modify limit: Invalid argument
-bash: ulimit: max user processes: cannot modify limit: Operation not permitted

export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$ "
export CLICOLOR=1
export LSCOLORS=ExFxBxDxCxegedabagacad
alias ls='ls -GF'
alias ll='ls -GFl'

export JAVA_HOME=$(/usr/libexec/java_home)
export LC_CTYPE="en_US.UTF-8"

# System-wide .bashrc file for interactive bash(1) shells.
if [ -z "$PS1" ]; then
   return
fi

PS1='\h:\W \u\$ '
# Make bash check its window size after a process completes
shopt -s checkwinsize
# Tell the terminal about the working directory at each prompt.
if [ "$TERM_PROGRAM" == "Apple_Terminal" ] && [ -z "$INSIDE_EMACS" ]; then
    update_terminal_cwd() {
        # Identify the directory using a "file:" scheme URL,
        # including the host name to disambiguate local vs.
        # remote connections. Percent-escape spaces.
    local SEARCH=' '
    local REPLACE='%20'
    local PWD_URL="file://$HOSTNAME${PWD//$SEARCH/$REPLACE}"
    printf '\e]7;%s\a' "$PWD_URL"
    }
    PROMPT_COMMAND="update_terminal_cwd; $PROMPT_COMMAND"
fi

最后我解决了这个问题。我发现OS X在打开新终端时会加载3个配置文件，它们是“/etc/bashrc”、“/etc/profile”、“~/.bash_profile”。我在“/etc/profile”的底部找到了两行关于ulimit配置的代码。我删除这2行并解决这个问题。

不管怎样，多亏了@Jonathan Leffler，你提醒我找到其他导致这个问题的配置文件。THX XD
