Question:

How do i pass arguments from one file to another and then execute a cmd ?

Scenario

2 files , file one is called solarisdisks and the other is called veritaslist

solarisdisk is :

c3t30d11
c3t30d12
c3t30d13
c3t30d14
c3t61d11
c3t61d12
c3t61d13
c3t61d14

veritaslist

hd3_3_11
hd3_3_12
hd3_3_13
hd3_3_14
hd3_61_11
hd3_61_12
hd3_61_13
hd3_61_14


what I want to do is once i have vxdg init <dgname> diskname=c?t?d?

I want to run is a command that will basically do

vxdg -g <dgname> adddisk <veritaslist>= <solarisdisk>

You could try arrays, something like:


VL=$(cat veritaslist)
set -A SL $(cat solarisdisk)
i=0
for vf in VL
do
vxdg -g <dgname> adddisk $vf = ${SL[i]}
(( i += 1 ))
done

A simple way to read data in from a file is to use the 'read' command.

while read yourVar
do
some commands with $yourVar
done < yourFile

Obviously, you could nest this...

while read yourVar1
do
while read yourVar2
do
some commands with $yourVar1 $yourVar2
done < yourFile2
done < yourFile1


Alternatively, if you're trying to work with 2 files simultaneously, do something like this...

paste -d"|" file1 file2 | while IFS="|" read file1Var file2Var
do
some commands with $file1var
some commands with $file2var
done

The -d flag and the setting of IFS is just to ensure that the line read from file 2 is always $fileVar2 as the files may be different lengths.

vxdg init stdg01 hd3_3_11=c3t30d11
paste -d"|" vertiasdisks sundisks | while IFS="|" read var1 var2
do
vxdg -g stdg01 adddisk $var1=$var2
done


this one has worked great for this cheers
