[Gambas-user] Shell command including string containing a quote

[John Rose]

Tobias,

Thanks for that useful reply.

I have a quick question (it doesn't seem worth asking on the Mailing List):
Using Dialog.OpenFile(), the resulting Dialog.Path shows the full path 
to the file (e.g. /home/john/x.txt). Given that the runtime user might 
change to a different directory (from that specified in Dialog.Path - 
/home/john/ - as a prior command to Dialog.OpenFile()) how can I obtain 
the new directory (e.g. /home/john/abc/) easily? I thought of using a 
string function to select characters before the final slash character 
but then the filename might contain a slash....

Regards,
John
