运行bash脚本时出现奇怪的问题
我编写了一个从网站获取歌词的 bash 脚本。脚本在这里--> http://scrippets.wordpress。 com/2011/02/01/fetching-lyrics-of-songs-from-the-terminal/（脚本中的缩进是正确的，与博客上的样子不同） 从终端执行该脚本时效果非常好。现在，我使用 compiz 命令创建了一个自定义键盘快捷键，按下正确的组合键时会执行以下命令：
gnome-terminal --working-directory="/home/tapan/sandbox/bash/" --window-with-profile=lyrics -e "/home/tapan/sandbox/bash/lyrics.sh" -t "`rhythmbox-client --print-playing`"
我创建了一个名为“lyrics”的新配置文件，为打开自定义外观的终端提供支持。当我使用此配置文件打开终端并运行脚本时，它再次完美运行。但是，当我使用键盘快捷键运行自定义命令时，出现以下错误：
Pink Floyd - Is There Anybody Out There?
wget: missing URL
Usage: wget [OPTION]... [URL]...
Try `wget --help' for more options.
cat: 3.txt: No such file or directory
我无法弄清楚出了什么问题。我的意思是，如果它通常在终端中工作得很好，为什么它不能工作呢？有什么建议吗？ PS：我写的脚本非常初级和新手，所以任何改进它的建议也欢迎在评论中:)
编辑：输出发生了一些变化，现在它只显示正在播放的歌曲的名称，没有其他内容。虽然有时它仍然显示 wget 错误。
EDIT2：当我从终端运行 gnome 终端命令时，它可以工作。仅当使用 compiz 命令通过键盘快捷键运行它或使用运行对话框（alt+f2 ）时才会出现问题。
I wrote a bash script that fetches lyrics from a website. The script is here --> http://scrippets.wordpress.com/2011/02/01/fetching-lyrics-of-songs-from-the-terminal/ (the indentations in the script are correct unlike how it looks on the blog)
This script works perfectly well when executed from the terminal. Now i created a custom keyboard shortcut using compiz commands, that executes the following command when the right key combination is pressed :
gnome-terminal --working-directory="/home/tapan/sandbox/bash/" --window-with-profile=lyrics -e "/home/tapan/sandbox/bash/lyrics.sh" -t "`rhythmbox-client --print-playing`"
I created a new profile called "lyrics" to give the terminal that opens up a custom look. When i open up a terminal with this profile and run the script, it works perfectly fine again. However, when i use the keyboard shortcut to run the custom command, i get the following error:
Pink Floyd - Is There Anybody Out There?
wget: missing URL
Usage: wget [OPTION]... [URL]...
Try `wget --help' for more options.
cat: 3.txt: No such file or directory
I cannot figure out whats wrong. I mean if it works perfectly well in the terminal normally, why shouldn't this work? Any suggestions?
PS: The script i have written is pretty elementary and noobish, so any suggestions to improve it are also welcome in the comments :)
EDIT: The output has changed a little, now it just shows the name of the song playing and nothing else. Though sometimes it still shows the wget error.
EDIT2: When i run that gnome terminal command from a terminal, it works. The problem is only when running it with the keyboard shortcut using compiz commands or if i use the run dialog (the alt+f2 one).

这两个 wget 命令可能应该将 url 变量放在双引号中，例如：
wget -q -U Mozilla -O 1.txt $link应该是wget -q -U Mozilla -O 1.txt“$link”The two wget commands should probably have the url variables in double quotes, for example:
wget -q -U Mozilla -O 1.txt $linkshould bewget -q -U Mozilla -O 1.txt "$link"您需要对歌曲标题进行 uriencode，以便“?”、“&”、“%”和“+”等特殊字符不会按字面意思传递到您的 URL 中。
将处理
?的。我不知道 bash 中是否有更通用的解决方案，无需求助于单行 Perl 或 Python 脚本。You need to uriencode your song title so that special characters like '?', '&', '%', and '+' are not passed literally in your URL.
will handle the
?'s. I don't know of a more general solution inbashwithout resorting to one-line Perl or Python scripts.
