Here’s how to get current Page Id from within a portlet in WebSphere Portal 6.1:

Linux cheat sheet

Posted by jacomac in Uncategorized on November 3rd, 2009

Empty an existing file: (see also here):
tail -5 my.log > my.log

Trigger a process and let it run while you’re logging out again (see also here):
nohup <command> &
or, for being able to reattach later, start with

  1. type screen and submit
  2. trigger your longer-running process
  3. detach with the sequence ctrl + a and ctrl + d
  4. logout
  5. later, when logging in again, you can reattach to that console session with:
    screen -r

for the latter, see also this tip.

Symbolic links (see also here):

  • Creation: ln -s target link_name
  • Removal: simply delete it using e.g. rm. It is a file of its own and deletion will not affect the target it is pointing at.
