[SOLVED] "Syntax error: operand expected ..." in script that was working right

Issue

I had a script that was doing well until now, I don't now what has changed, but the script is the same.

I had this variables:

SIZEKB=$[[(SIZE+1023)/1024]]
REQUIREDKB=$[[SIZEKB+MINFREEKB]]

Which I repeat were working ok, but now I got this error:

line 12: [(SIZE+1023)/1024]: syntax error: operand expected (error token is "[(SIZE+1023)/1024]")
line 13: [SIZEKB+MINFREEKB]: syntax error: operand expected (error token is "[SIZEKB+MINFREEKB]")

What should I change to correct the syntax, thanks!

Solution

The easiest way to write those assignment is to providean arithmetic context:

((SIZEKB=(SIZE+1023)/1024))
((REQUIREDKB=SIZEKB+MINFREEKB))

You can use also

SIZEKB=$[(SIZE+1023)/1024]
REQUIREDKB=$[SIZEKB+MINFREEKB]

but this is deprecated and provided for compatibility with old scripts (perhaps those written for bash version 1?).
