Question

我想知道是否有人可以帮助弄清楚为什么我的简单bash脚本无法正常工作，我不断得到：

svn：找不到命令

即使我安装了svn，它在我的脚本之外也能正常工作。

    #!/bin/bash

    ## Get Directory Path From User
    printf "\n";
    printf "Uses of ~/ or . To Designate Directory Structure Will Not Work!\n"
    printf "\n";

    printf "Please Enter The FULL Path To The Directory\n"
    printf "Where We Shall Create Copy of Slides\n"
    read PATH

    ## If Path Is Valid
    if [ -d "$PATH" ]; then

        printf "Valid Path To Directory Entered\n"

        ## Attempt To Copy Files From SVN On Bluenose
        `svn checkout https://svn.cs.dal.ca/csci2132/all/slides/ $Path`

        printf "All Slides Have Been Copied To " 
        printf $PATH + "\n"
        printf "\n"

    ## Invalid Path Entered Tell User And Exit
    else
        printf "Invalid Path Entered\n";
        printf "Please Try Again\n";
        exit 0;
    fi

    printf "Task Complete\n"

shell查看PATH中以冒号分隔的目录列表以查找可执行文件。由于您已使用名称PATH作为目标目标，因此它正在寻找svn。只需为变量选择一个不同的名称。也就是说，不要覆盖PATH。

为什么我得到＆＃34; svn：命令未找到＆＃34;
