Operating Systems Linux Red Hat Error when executing script Post 302996116 by rbatte1 on Wednesday 19th of April 2017 07:14:19 AM

It would be safer to wrap the entire assignment in double quotes as a common practice so that if you accidentally assign a space to either variable, then the assignment to DIR1 or DIR2 will not fail:-
Code:
HI_VAR="TextOnly"
LO_VAR="Text and space"

MY_VAR1="${HI_VAR}${LO_VAR}_other_text"
MY_VAR2=${HI_VAR}${LO_VAR}"_other_text"       # May fail in some shells

I always clearly mark the variable name with curly braces { & } to ensure I don't confuse the variable with any literal text or underscores that follow. You can get trapped with things like this:-
Code:
/home/rbatte1> V1="Hello"
/home/rbatte1> V2="$V1_Goodbye"
/home/rbatte1> echo "\$V2=\"$V2\""
$V2=""

This is because the assignment is looking for variable V1_Goodbye (equivalent to ${V1_Goodbye} ) which has not been set.

I would also suggest that you could consolidate commands such that you just do this:-
Code:
MONTHYEAR=$(date +%b%Y)
DIR1="${MONTHYEAR}_Blast_BC01"

Of course, it depends what you use the values for elsewhere.



I hope that this helps,
Robin
