如何在 Linux Mint 中为 Lightshot 创建 PrtSc（打印屏幕）快捷方式

我使用 Linux Mint 18.3 Cinnamon 64 位。我已经xdotool安装了。

光射自登录以来一直在运行，我使用启动应用程序工具在登录后立即创建启动：

env WINEPREFIX="/home/vlastimil/.lightshot" wine C:\\windows\\command\\start.exe /Unix /home/vlastimil/.lightshot/dosdevices/c:/users/Public/Start\ Menu/Programs/Lightshot/Lightshot.lnk

目标：

按PrtSc（打印屏幕键）并进入全屏剪切模式（事实上，与 Windows 下的 Lightshot 具有相同的功能）。

什么有效（当从运行时gnome-terminal）：

xdotool key --window $(xdotool search --limit 1 --all --pid $(pgrep Lightshot) --name Lightshot) "Print"

但是，如果将其复制粘贴到添加自定义快捷方式对话框：

添加自定义快捷方式对话框

我只是想知道为什么会这样，更重要的是，如何让它发挥作用？

原因可能是，我没有指定要运行的任何 shell，因此以下内容有效：

sh -c 'xdotool key --window $(xdotool search --limit 1 --all --pid $(pgrep Lightshot) --name Lightshot) "Print"'

编辑：

可能值得注意的是，我现在决定为其编写一个脚本。充分验证每一步：

#!/bin/sh

is_number()
{
    # check if exactly one argument has been passed
    test "$#" -eq 1 || print_error_and_exit 5 "is_number(): There has not been passed exactly one argument!"

    # check if the argument is an integer
    test "$1" -eq "$1" 2>/dev/null
}

# ------------------------------------------------------------------------------

print_error_and_exit()
{
    # check if exactly two arguments have been passed
    test "$#" -eq 2 || print_error_and_exit 3 "print_error_and_exit(): There have not been passed exactly two arguments!"

    # check if the first argument is a number
    is_number "$1" || print_error_and_exit 4 "print_error_and_exit(): The argument #1 is not a number!"

    # check if we have color support
    if [ -x /usr/bin/tput ] && tput setaf 1 > /dev/null 2>&1
    then
        bold=$(tput bold)
        red=$(tput setaf 1)
        nocolor=$(tput sgr0)
        echo "$bold$red$2 Exit code = $1.$nocolor" 1>&2
    else
        echo "$2 Exit code = $1." 1>&2
    fi

    exit "$1"
}

# ------------------------------------------------------------------------------

check_for_prerequisite()
{
    # check if exactly one argument has been passed
    test "$#" -eq 1 || print_error_and_exit 2 "check_for_prerequisite(): There has not been passed exactly one argument!"

    # check if the argument is a program which is installed
    command -v "$1" > /dev/null 2>&1 || print_error_and_exit 6 "check_for_prerequisite(): I require $1 but it's not installed :-("
}

# ------------------------------------------------------------------------------

# check if no arguments have been passed to the script
test "$#" -gt 0 && print_error_and_exit 1 "$0: You have passed some unexpected argument(s) to the script!"

# ------------------------------------------------------------------------------

# check for prerequisites
check_for_prerequisite "pgrep"
check_for_prerequisite "xdotool"

# ------------------------------------------------------------------------------

# global constants
lightshot_key="Print"
lightshot_name="Lightshot"

# ------------------------------------------------------------------------------

# get the lightshot pid
lightshot_pid=$(pgrep "$lightshot_name")

# test if a pid has been successfully acquired
is_number "$lightshot_pid" || print_error_and_exit 7 "lightshot_pid: The argument is not a number!\\nLightshot is most probably not running."

# ------------------------------------------------------------------------------

# get the window id from lightshot pid
lightshot_wnd=$(xdotool search --limit 1 --all --pid "$lightshot_pid" --name "$lightshot_name")

# test if a window handler has been successfully acquired
is_number "$lightshot_wnd" || print_error_and_exit 8 "lightshot_wnd: The argument is not a number!\\nLightshot is most probably not running."

# ------------------------------------------------------------------------------

# simulate a print screen key press on the lightshot window
xdotool key --window "$lightshot_wnd" "$lightshot_key"
