Hi
I have a variable BIT1 which holds some value. Is there a way to retrieve the value of this variable indirectly via another variable, lets say SUBSET_BIT_NUM=1, so the call will look something like this:
sundev1 $ echo ${BIT${SUBSET_BIT_NUM}}
ksh: ${BIT${SUBSET_BIT_NUM}}: bad substitution
Thanks a lot for any advice -A
#!/bin/ksh
BIT1=aoussenko
BIT2=foo
SUBSET_BIT_NUM=1
eval echo \${BIT${SUBSET_BIT_NUM}}
The following also works
eval echo '${BIT'${SUBSET_BIT_NUM}'}'
That's not very reliable:
BITTER=qwerty
SUBSET_BIT_NUM=TER
IFS=E
eval echo '$BIT'$SUBSET_BIT_NUM ## unreliable
eval echo "\$BIT$SUBSET_BIT_NUM" ## correct
The output is:
R
qwerty
