I'm getting pretty frustrated with this problem at the moment. I can't see what I'm doing wrong. I have this problem with google chrome that it gives a notice of not being shut down properly. I want to get rid of this. Also I have some older replaces that have to do with full screen size. In bash, all the lines produce the expected result; however, in a script file, it produces an empty settings file...
我此刻对此问题感到非常沮丧。我看不出我做错了什么。我有谷歌Chrome的这个问题,它给出了没有正确关闭的通知。我想摆脱这个。此外,我还有一些与全屏尺寸有关的旧版更换。在bash中,所有行都产生预期的结果;但是,在脚本文件中,它会生成一个空的设置文件...
These lines are in the file:
这些行在文件中:
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"work_area_bottom.*/\"work_area_bottom\": $(xrandr | grep \* | cut -d' ' -f4 | cut -d'x' -f2),/" > ~/.config/google-chrome/Default/Preferences
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"bottom.*/\"bottom\": $(xrandr | grep \* | cut -d' ' -f4 | cut -d'x' -f2),/" > ~/.config/google-chrome/Default/Preferences
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"work_area_right.*/\"work_area_right\": $(xrandr | grep \* | cut -d' ' -f4 | cut -d'x' -f1),/" > ~/.config/google-chrome/Default/Preferences
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"right.*/\"right\": $(xrandr | grep \* | cut -d' ' -f4 | cut -d'x' -f1),/" > ~/.config/google-chrome/Default/Preferences
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"exit_type.*/\"exit_type\": \"Normal\",/" > ~/.config/google-chrome/Default/Preferences
cat ~/.config/google-chrome/Default/Preferences | perl -pe "s/\"exited_cleanly.*/\"exited_cleanly\": true,/" > ~/.config/google-chrome/Default/Preferences
I've been googling a lot for this issue; however, I do not get the right search words to get a helpful result.
我一直在谷歌上搜索这个问题;但是,我没有得到正确的搜索词来获得有用的结果。
Problem is solved by using the perl -p -i -e option like so:
通过使用perl -p -i -e选项解决问题,如下所示:
perl -p -i -e "s/\"exit_type.*/\"exit_type\": \"Normal\",/" ~/.config/google_chrome/Default/Preferences
The above line is enough to get rid of the Google chrome message of incorrect shutdown
以上行足以摆脱不正确关机的Google Chrome消息

Your problem is almost certainly:
你的问题几乎可以肯定:
> ~/.config/google-chrome/Default/Preferences
Because that > says 'truncate the file'. And worse - it does this first before starting to read it. So you truncate the file before reading it, resulting in a zero length file feeding into a zero length file.
因为那>说'截断文件'。更糟糕的是 - 它在开始阅读之前首先执行此操作。因此,在读取文件之前截断文件,导致零长度文件进入零长度文件。
I would suggest you want to do this exclusively in perl, rather than a halfway house. perl supports the -i option for an "in place edit".
我建议你只想在perl中这样做,而不是在中途宿舍。 perl支持-in选项进行“就地编辑”。
Or just write your script in perl to start with. (If give sample input and output, knocking up an example that'll do what you want will be quite straightforward).
或者只需在perl中编写脚本即可。 (如果给出样本输入和输出,那么敲一个能做你想做的事的例子就会非常简单)。

If you need search and replace some text I suggest use:
如果您需要搜索并替换一些文本我建议使用:
ack -l --print0 '2011...' ~/.config/google-chrome/Default/Preferences | xargs -0 -n 1 sed -i -e 's/2011../2015.../g'
