gnome-terminal命令可从命令行运行，但不能从Cinnamon快捷方式（或脚本）运行

Question

I am using Linux Mint 17 and Google Chrome.

I often check the weather before going out walking; to do this I surf to http://www.mwis.org.uk/scottish-forecast/EH/ where I then have to click on the PDF doc to see the isobar weather map.

I thought to shorten this process so that the current PDF can be displayed with a simple keyboard shortcut; I've assigned windows key + F8 to this task. However it's not working using gnome-terminal.

I have something wrong with my gnome-terminal syntax, and after some level of googling I'm not really sure what it is.

So, the following does not work, as a shortcut, or when called from a script.

gnome-terminal -x bash -c myvar=$(curl http://www.mwis.org.uk/scottish-forecast/EH | grep EH-MWI | grep -o -P '(?<=forecasts/).*(?=" target)'); google-chrome http://www.mwis.org.uk/pdf/weather-forecasts/$myvar

.. but it does work when placed directly in the command line.

(I started on the command line with

myvar=$(curl http://www.mwis.org.uk/scottish-forecast/EH | grep EH-MWI | grep -o -P '(?<=forecasts/).*(?=" target)')
google-chrome http://www.mwis.org.uk/pdf/weather-forecasts/$myvar

which does exactly what it is supposed to.)

Can anyone suggest the correct shortcut gnome-terminal command for Cinnamon?

Answer 1

The argument to bash -c needs to be a single quoted string ("single" as in "one unit", not necessarily specifically within single quotes).

bash -c 'google-chrome http://www.mwis.org.uk/pdf/weather-forecasts/"$(curl http://www.mwis.org.uk/scottish-forecast/EH | grep EH-MWI | grep -o -P "(?<=forecasts/).*(?=\" target)")"'

I had to change some single quotes to double, as the whole quoted argument obviously cannot contain single quotes (though you could pass it double-quoted instead, or individually backslash-escape each shell metacharacter).

I also factored out the variable.
