are Associative Arrays possible in UNIX?

Is it possible to say..

myArr['filename']=34
myArr['next_filename']=15

?

Korn shell 93 supports associative arrays.

oh..

I see. That's very useful hmm.

Is the value of myArr[1] the same value as myArr[01]?
or myArr[0] same as myArr[00] ?

About the 02 vs 2 thing...

From other programming language experience I'd guess not since putting zero at the front usually indicates on octal value (0x2 is hexadecimal out of interest by the way).

I've never tested on bash scripts though so wait for an expert answer Smilie

Posix, in their wisdom, has said that shells should treat integer constants with a leading zero as octal. Both ksh and bash now comply. You may have an older ksh or bash that doesn't work like that.

damn

Ah damn, then I'm definitely running an older version of ksh/bash.
Because myArr[01] was the same as myArr[1].
