Question

I wanted to open a file in notepad(using JAVA) by…

proc.exec(“notepad “+curDir+”\auto_saved.txt”);

where…

 String curDir = System.getProperty("user.home");
 curDir=curDir+"/txt-files";                
 Runtime proc = Runtime.getRuntime();

this works properly in WIN7 but says ‘home……….\auto_saved.txt’ PATH not found. in LINUX.
but if I save a file to (curDir+”\auto_saved.txt”);..it creates a file and saves it in LINUX.

So, how to open a file in /home/user/some-folder/…??

Answer 1

1. There is no notepad editor in Linux. Many linux distributions have a text editor called “nano”, in /usr/bin/nano; Ubuntu/Debian puts a text editor in /etc/alternatives/editor ; you could also also check env{EDITOR}, which sometimes contains a user set pathname to a text editor, and override your choice of editor if present to allow for user customization.
2. You might want to use the full path to the executable when you call exec, in case it is not on the path.
