Subject: use string as variable name
Date: Sun, 23 Jan 2022 10:58:36 +0100	[thread overview]
Message-ID: <trinity-82a62e55-a3b0-43a3-8656-8a983119c309-1642931916783@3c-app-gmx-bs30> (raw)

Hi,

is it possible to use a string as variable-name?

example:

i=1
img_$i=foo

now i have defined $img_1, but how to display it using $i again?

echo ${img_$i}
echo ${img_${i}}

alternative may be a variable-array, but it seems not possible

img[$i]=bar
img[1]=bar: No such file or directory

i just want to create a dynamic list and access the items of this list by index

another way may be appending new string with separator to existing string and split afterwards,
but then i have the index-problem again.

i know barebox shell is limited (but much more mighty than expected for just a bootloader),
but maybe it is possible :)

any idea?

regards Frank
