Trying Vshnu: Impressions

I use bash a fair amount.  I am no scripting expert, but I am comfortable navigating directories and manipulating files.  vshnu looked faster at managing  these tasks.  I really liked it the first time I selected a text file and it opened right up into vim. 

In my opinion, vshnu has a steep learning curve.  It did not feel intuitive right away, but powerful programs rarely do.  vshnu joins good company like vim and screen; I felt lost the first few times I used them, but slowly they have become old friends.

Here is an example using vshnu.  I want to zip each file in this folder except readme.txt

benjamen@homer:/home/benjamen/irenhanc
a  .
b  ..
c  AMX.prc
d  IrLib.prc
e  SerIrCommLib.prc
f  SerialIrPnl.prc
g> readme.txt
                                                                                Thu Jul 20 16:09:07 2006

I  type '/' to put me into chose mode

benjamen@homer:/home/benjamen/irenhanc
a  .
b  ..
c  AMX.prc
d  IrLib.prc
e  SerIrCommLib.prc
f  SerialIrPnl.prc
g> readme.txt
keys=choose                                                                Thu Jul 20 16:11:31 2006


Then I type 'c', 'd', 'e', and 'f', to choose the files next to these letters.

benjamen@homer:/home/benjamen/irenhanc
a  .
b  ..
c 1AMX.prc
d 2IrLib.prc
e 3SerIrCommLib.prc
f>4SerialIrPnl.prc
g  readme.txt
4 chosen, keys=choose                                                  Thu Jul 20 16:11:31 2006

Typing ':'  then 'gzip' will execute the shell command on the chosen files

benjamen@homer:/home/benjamen/irenhanc
a  .
b  ..
c 1AMX.prc
d 2IrLib.prc
e 3SerIrCommLib.prc
f>4SerialIrPnl.prc
g  readme.txt
4 chosen, keys=choose                                         Thu Jul 20 16:11:31 2006
(Shell: gzip)


Hitting return a few times the files are gzipped.

benjamen@homer:/home/benjamen/irenhanc
a  .
b  ..
c  AMX.prc.gz
d  IrLib.prc.gz
e  SerIrCommLib.prc.gz
f> SerialIrPnl.prc.gz
g  readme.txt
                                                                                 Thu Jul 20 16:16:27 2006

This is not a very deep look at vshnu; rather it is a taste of its capabilities.  I do not think I will start using vshnu on a day to day basis yet, but I'm not uninstalling it either.

  1. Hi Benjamen
    From one of your posts in 2006 you seem to be one of the last possessors of the Visor Deluxe file SerIrCommLib.prc which is used to configure the pda for infrared work.
    Might you still have it? Because it has dropped off the Palm website and it would be great to get a copy from you.
