define Variables from file content. 1

[mrn]

I have a file containing

ENC0
ENC1
....

how would I read the file contents and assign each line to a variable?

VAR1=ENC0
VAR2=ENC1
VAR3=.....

The lines (enclosure type) vary depending on the SAN type, we could have more than two lines.

I know I could use

awk 'NR==1'
awk 'NR==2'

Here's one way:

[tt]((i=1))
for line in $(</path/to_file)
do
eval VAR$i=$line
(( i=i+1 ))
done[/tt]

Thanks p5,

Why not

set -A array $(< file)

then the lines will be ${array[0]}, ${array[1]}, etc.

However, see my comments on thread822-1451806

You can use the positional parameters to hold the values:

[tt]set -- $(</path_to_file)

for i
do
echo var is $i
done[/tt]

Arrays of course.

p5 good idea but I'm using this in a function and want to use the vars in other functions

so now I've got

get_enc() {

vxdmpadm listenclosure all | grep -w CONNECTED | grep -v DISKS|awk '(print $3)' > /tmp/list_enc.out

set -A array $(< /tmp/list_enc.out)
CAB1=${array[0]}
CAB2=${array[1]}
}

WARNING!!! WARNING!!! UUOG alert! Pedantic purist alert!

Joking apart, grep and awk as part of the same statement can always be simplified - try

vxdmpadm listenclosure all |awk '/CONNECTED/ && ! /DISKS/ {print $3}' > /tmp/list_enc.out

Cheers for that, I guess I'm just lazy ;-)
