Linux fc tips

fc is a command in Linux which I can't seem to remember no matter how many distros I hopped onto.

So I post this as a reminder, as well as for the benefit of anyone who despise reading man pages :)

To list your executed command history:

fc -l

The above will lists the commands with line numbers on the left like so:

492  unrar x some.part1.rar
493  sync;exit
494  python editor_test.py 
495  cd Documents/python_editor/
496  vi test.py
497  python test.py

To execute command history number 495 above:

fc -s 495

To edit it before executing however, use the one below.
After you exit the editor, the command will be executed:

fc 495

If you would like to execute the last command with the word 'mailer' in it:

!?mailer?

Ensuring UTF-8 encoded files compile in Staticmatic

Pages with Russian characters are stored (AFAIK) encoded using UTF-8. Unfortunately, this encoding is not compilable by Staticmatic.

A simple workaround is to insert a blank line at the start of the page like so:



Problem solved :)

JBoss web service blocked

If you have a web service in JBoss of which you can access the WSDL but keep getting "connection refused" error when accessing the service, then the culprit is normally this:

C:\jboss-4.2.2.GA\bin\run.bat -b 0.0.0.0

or

C:\jboss-4.2.2.GA\bin\run.bat

A solution - at least what worked for me - was to use the actual IP of the machine like so:

C:\jboss-4.2.2.GA\bin\run.bat -b 192.168.1.11

Its funny how modifying JBoss startup scripts did not affect the "-b" option above. However specifying it on the command line works fine.
