[Level 2] Bash completion in Ubuntu

As we know, we can use "tab" for word completion.
And now, you can also use "tab" for bash completion.
That means when you finished typing your command,
ex. # apt-get
and you press "tab", then you will get the options for apt-get.
# apt-get
autoclean        clean            purge            upgrade
autoremove       dist-upgrade     remove          
build-dep        dselect-upgrade  source          
check            install          update

How could you enable this feature?
add the following command in your ~/.bashrc, if not exists.
if [ -f /etc/bash_completion ] then;
    . /etc/bash_completion
fi


Wish this helps.

[Level 1] Rar tool for Solaris.

Sometimes we will got a rar compressed file from our friends, but there is no default tool in OpenSolaris to decompress the rar filess. We can got a Solaris Intel version from rarlab . The steps as the following: 1. down load the rar tools from rarlab. http://www.rarlab.com/rar_add.htm 2. uncompressed the source. # gunzip ./unrar-sol-intel.gz 3. move it to the location you used to. # mv /unrar-sol-intel.gz /usr/bin/unrar 4. try to decomprss # unrar x ./test.rar Wish this helps. regards, Stanley Huang

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
