Description:
unexpected bad substitution:
enter the following simple list:
prompt: CLUSTER='1 2'; echo ${CLUSTER/${HOSTNAME%%.*}}
output: 1 2
the idea of the above line is to remove short HOSTNAME (without the
trailing domain)
from the CLUSTER - works fine (CLUSTER was assigned a dummy
value - irrelevant)
however the same operation with slash results in a bad substitution
error.
the substitution appears to be a valid one.
prompt: CLUSTER='1 2'; echo ${CLUSTER/${HOSTNAME/.*}}
output: -bash: ${HOSTNAME: bad substitution
Apparently bash interprets this as ${parameter/pattern/string}
where pattern = ${HOSTNAME. Looks like a bug; it works in ksh.
As a workaround, you could use:
H=${HOSTNAME/.*}
echo ${CLUSTER/$H}
