列表文件，并显示在使用bash菜单 [英] List files and show them in a menu with bash

问题描述

我尝试使用目录中的文件作为一个bash脚本选项。用户应该能够选择一个，然后通过所选择的文件的名称到一个变量。到目前为止，我能得到的文件列表，但几个小时后，尝试我无法弄清楚如何将它们显示为选项。

I am trying to use the files in a directory as options in a bash script. The user should be able to select one and then pass the name of the selected file into a variable. So far I can get the list of files, but after a few hours trying I can't figure out how to show them as options.

#!/bin/bash
prompt="Please select a file:"
options=( $(find -maxdepth 1 -print0 | xargs -0) )

PS3="$prompt "
select opt in "${options[@]}" "Quit"; do 

    case "$REPLY" in
    for i in "${options[@]}"
    do
    $i' ) echo "You picked $opt which is file $REPLY";;'
    done    
    $(( ${#options[@]}+1 )) ) echo "Goodbye!"; break;;
    *) echo "Invalid option. Try another one.";continue;;

    esac

done

任何帮助很多AP preciated。谢谢！

Any help is much appreciated. Thanks!

推荐答案

我不认为情况是适合这里：

#!/bin/bash
prompt="Please select a file:"
options=( $(find -maxdepth 1 -print0 | xargs -0) )

PS3="$prompt "
select opt in "${options[@]}" "Quit" ; do 
    if (( REPLY == 1 + ${#options[@]} )) ; then
        exit

    elif (( REPLY > 0 && REPLY <= ${#options[@]} )) ; then
        echo  "You picked $opt which is file $REPLY"
        break

    else
        echo "Invalid option. Try another one."
    fi
done    

ls -ld $opt
