将别名命令从tcsh转换为bash

Question

I'm new to bash. I want to convert below alias command form tcsh to bash:

alias buzz 'echo \!$;if (-e ~/.sshelp.txt) grep -i \!$ ~/.sshelp.txt && echo \!$;if (-e ~/.sshelp_qct.txt) grep -i \!$ ~/.sshelp_qct.txt '

I tried below command but it doesn't work. Any suggestions?

alias buzz= 'echo \!$;if (-e ~/.sshelp.txt) grep -i \!$ ~/.sshelp.txt && echo \!$;if (-e ~/.sshelp_qct.txt) grep -i \!$ ~/.sshelp_qct.txt '

Define a function in bash . C shells define aliases because they don't support functions. I think the following is (roughly) equivalent.

buzz () {
    echo "$1"
    if [ -e ~/.sshelp.txt ]; then
        grep -i "$1" ~/.sshelp.txt && echo "$1"
    fi
    echo "$1"
    if [ -e ~/.sshelp_qct.txt ]; then
        grep -i "$1" ~/.sshelp_qct.txt
    fi
}
