如何在bash中不使用tilde和tab completion来解析所有用户

打开文件 /usr/share/bash-completion/bash_completion 找到函数 tilde() (在941号线附近)。在这里,只需标出行号 946 . 最后,函数应如下所示:

# Perform tilde (~) completion
# @return  True (0) if completion needs further processing,
#          False (> 0) if tilde is followed by a valid username, completions
#          are put in COMPREPLY and no further processing is necessary.
_tilde()
{
    local result=0
    if [[ $1 == \~* && $1 != */* ]]; then
        # Try generate ~username completions
        #COMPREPLY=( $( compgen -P '~' -u "${1#\~}" ) )
        result=${#COMPREPLY[@]}
        # 2>/dev/null for direct invocation, e.g. in the _tilde unit test
        [[ $result -gt 0 ]] && compopt -o filenames 2>/dev/null
    fi
    return $result
}

试试看。
