Operating Systems Linux Red Hat Error when executing script Post 302996131 by MadeInGermany on Wednesday 19th of April 2017 12:58:11 PM

Yes, a consolidation makes sense.
Code:
MONTHYEAR=$(date +%b%Y)
DIR1=${MONTHYEAR}_Blast_BC01
DIR2=${MONTHYEAR}_Blast_BC15

""Quoting of variables is never a mistake. Especially beginners should do it always!
But - now for the advanced user - the quoting of an assignment value is only needed if there is a literal space.
Code:
DIR3="${MONTHYEAR} Blast BC15"
echo "$DIR3"

Not if the space comes from a variable
Code:
NAME="Blast BC15 *"
DIR3=${MONTHYEAR}_$NAME
echo "$DIR3"

The latter is not an assignment - the argument for the echo command must be quoted!
Other
Code:
case ${MONTHYEAR}_$NAME in ...

Code:
[[ ${MONTHYEAR}_$NAME ... ]]

In all other cases the shell does first variable substitution then word splitting then globbing.
Last but not least, the [ ] is a false friend:
Code:
[ "${MONTHYEAR}_$NAME" ... ]

In fact the [ is a command and its arguments must be quoted!
