Data need help with some commands please

In my unix machine I have the following setup.

root 7 Dec 13 10:02 Beta10 -> current
root 7 Dec 13 10:05 Beta11 -> current
root 7 Dec 13 10:06 Beta12 -> current
root 7 Dec 13 10:06 Beta13 -> current
root 7 Dec 13 10:07 Beta14 -> current
root 7 Dec 13 10:08 Beta15 -> current
root 7 Dec 13 10:02 current -> pub/TRIAL16

I used the following commands to set this up:

ln -sf current Beta15
ln -sf pub/TRIAL16flashimage.tgz.rsa current

Here is my question. Instead of manually telling every PC that contains BetaXX to download the 'current' file, how can I write this and say if any PC is NOT equal to current, then download current, otherwise do nothing.

Im new at this, please help.. I don't know if unix commands have IF, ELSE and THEN statements...

thanks

Hi mujtba,

Probably I can not provide you complete help on how to tell every PC to download the 'current file' which contains BetaXX, but I can give you guarantee that unix does has IF, ELSE,.... statements. You might want to look Shell Programming books.

All the best, and please do keep post if you found the answer

Regards

hkhan12,

I don't understand you posting. You said download? or Link? Your command is for linking files but I think you would like to something like this:

#!/bin/ksh

typeset -i counter

counter=1

while (( $counter < 100 ))
do

ln -sf current Beta$counter
counter="$counter+1"

done


This will loop throught (100X) and only get the BeatXX PC no other. Unless you want to add a if statment in there. I hop ethis help.
