Error when opening Eclipse Application

Issue: Normally when I first install eclipse, it gives me a popup window to choose my workspace but once I select the workspace and say that it is the default one...Eclipse doesn't show that window again...This window is the "Workspace Launcher" If at all in the future I want to change the workspace I used to do so after opening eclipse and then choosing "Switch Workspace" in the File menu...This restarts eclipse and opens it again in the new workspace! It was when I got this error while opening the application.

Solution:
The default workspace is stored in the configuration\config.ini file, usually found where you installed Eclipse. If there isn't a default there (it's called osgi.instance.area) then it will prompt. If you have previously selected one, and clicked 'make this the default', then I believe it updates it in the config.ini file; if not, look in configuration\.settings\org.eclipse.ui.ide.prefs.
This files looks like this:

1--- #Sat May 31 15:23:28 GMT+05:30 2008
2--- RECENT_WORKSPACES_PROTOCOL=2
3--- MAX_RECENT_WORKSPACES=5
4--- SHOW_WORKSPACE_SELECTION_DIALOG=true
5--- eclipse.preferences.version=1RECENT_WORKSPACES=D\:\\JavaProjs

See that the 4th line gives you the option to show the workspace selection dialog box...If you want the selection everytime from now on...Just make this true else make it false

See the 5th line this will have the list of workspaces you have worked with till now...In this case it can have upto 5 entries! 5 is defined in line 3! If you want to change the workspace for this time just add or change the entry in line 5!

Save the file and reopen eclipse! It will open! Enjoy your coding!

wget error–“zsh: parse error near &”

There is no doubt that I prefer wget way over any other type of downloads…Syntax: wget <DOWNLOAD_URL>If you get this error “zsh: parse error near &” then its probably because your download URL has a “&” so you should try giving your DOWNLOAD_URL in double quoteswget “<DOWNLOAD_URL>”If you are trying to download from a site which needs you to give your credentials then you can try giving it this waywget --http-user=<UserName> --http-password=<Password> “<DOWNLOAD_URL>”Hope this helps
