Simple script
Hi All,

First time poster so be gentle - Also apologies if this is in the wrong section.

I am not a unix administrator but as a Storage administrator know enouh to get me by for what I need to do.

However I am having a slow night-shift so I am playing about with a bit of scripting to make getting information of an EMC array a little easier.

I have this command:
Code:
symcfg -sid 1474 -fa all list

which gives this output:


Code:
Symmetrix ID: 000284701474
           S Y M M E T R I X    F I B R E   D I R E C T O R S
    Dir    Port  WWN               VCM      Volume Set   Pnt to Pnt

    FA-14B  1    500604843e0cc8bd  Yes      Yes          Yes

What I want to do is pass column 1 & 2 into another command for different output.
The twist is I in column 1 I need to get rid of the "FA-" bit.

I have tried something like:

Code:
symcfg -sid 1474 -fa all list | awk '{print $1, $2}' | grep -v 'FA-'

However this removes the whole FA- and the number and letter afterwards.

The plan is to eventually do something like:

Code:
for i in `symcfg -sid 1474 -fa all list | awk '{print $1}' | grep -v 'FA-'`
for n in `symcfg -sid 1474 -fa all list | awk '{print $2}'`
do
echo "symmaskdb -sid 1474 -dir $i -p $n  list database -nop"
symmaskdb -sid 1474 -dir $i -p $n  list database -nop >> 1474_list_database
done

I also sure I am going to get problems with the above command as well but first things first.

Any help you can give would be great.

Cheers
Colin

Hi, perhaps this
Code:
awk -F'[ \t-]*' '{print $2, $3}'

is the filter you are looking for..

---------- Post updated at 22:32 ---------- Previous update was at 22:27 ----------

I think it may be easier to just use shell, like so for instance:
Code:
symcfg -sid 1474 -fa all list | {
read;read;read;read                                   # cut out the first 4 lines of the output
while IFS='[ \t-]' read x director port x; do
  echo "symmaskdb -sid 1474 -dir $director -p $port list database -nop"
done
}

Scrutinizer,
Thanks for the response dude however like I said I am no administrator so can guess at what these commands do but that is about it. unfortuantely neither are working for me.

This returns about the same amount of lines as I would expect from my output however all the lines are blank. What does the [\t-]* actually do? I have tried searching the man pages but cannot see this.

while IFS='[ \t-]' read x director port x; do
  echo "symmaskdb -sid 1474 -dir $director -p $port list database -nop"
done
}

This returns an error message "read: missing argument" I assumed the read like your comments like you said were just to not read the first few lines (which is useful to know by the way).

Apologies for being a bit dense. Its at times like these I realise how little I know about UNIX and scripting.

Thanks for your help and suggestions though

Hi, what happens if you replace that line with:
Code:
read x;read x;read x;read x                           # cut out the first 4 lines of the output

What is you OS?

About awk:
-F'[ \t-]* changes the field separator to any space, tab or - character and makes awk consider repetions of the characters as a single separator

Okay okay - slightly further this time:

Code:

opsan00@dyeccs01 > while IFS='[ \t-]' read x director port x; do
opsan00@dyeccs01 > echo "symmaskdb -sid 1474 -dir $director -p $port list database -nop"
opsan00@dyeccs01 > done
opsan00@dyeccs01 > }

I think I the curcial bit of the script is the bit I least understand:
Code:
while IFS='[ \t-]' read x director port x

I assume that the director and port are parameters and hence why they are passed into the echo command - correct?
However how does it know what these parameters are without awk column 1 & 2?

I am probably getting this wrong but I think if I can get my head round this then I will be able to understand what the script is doing and may even be able to troubleshoot it better myself Smilie

I also thought I understood your awk parameters and tried to change it slightly which made it output the whole command - I will need to see if there is a way I can figure out how to do this - the more I use awk the more l like it.

Code:
# symcfg -sid 1474 -fa all list | awk -F'[ \tFA-]*' '{print $1}'

Hi, could you try if it makes a difference if you replace that line with this?
Code:
while IFS="-$IFS" read x director port x; do

Otherwise, what is your OS?
Can you post the output of this command?
Code:
symcfg -sid 1474 -fa all list | awk 'NR==5' | od -c

First things first:

O/S is:
Code:
# uname -a
SunOS 5.8 Generic_117000-05 sun4u sparc SUNW,Sun-Fire-V240
#

This command worked better this time and is passing the right parameters into command which is great - however it is not quite working when I use it properly:

Code:
# symcfg -sid 1474 -fa all list | {
> read x;read x;read x;read x
> while IFS="-$IFS" read x director port x; do

I cannot tell you how much this is going to help me with many different commands. can you break down the command for me so I can understand how this works - once I understand I can then use for many other different queries and troubleshooting.

As for the other command it did not really return anything - but here is the output:

Code:
# symcfg -sid 1474 -fa all list | awk 'NR==5' | od -c
0000000  \n
0000001
#

Again thanks for your help.
