I have this insane distrust of compilers and interpreters.
So I do what could be called naive coding in most langauages that I know well enough because of this distrust.
This is one example of my naive code and IS actually inside AudioScope.sh.
Derivatives of this have never failed under normal conditions on the langauges I have used so it seems idiot proof.
Would professionals like yourselvs consider this puerile coding?
That's just about the most difficult way possible to solve the problem. I only resort to it when the language features just can't handle it (i.e. needing to build a recursive parser from scratch).
When you find yourself doing this for trivial things, you're definitely overthinking it. Try inverting the problem. What if you looked for exactly one non-numeric character? You only need to find one to prove the string's bad, and if you can't... fait accompli.
One way:
This is portable across all bourne shells. In BASH, you could reduce it to a single statement.
I apologise because I had pasted this question in the newbies forum first (because i am a bit of a newbie) but thought it might be better suited in here

HI,
Can some one guide me how to make changes to the script below so that it can load the history of a program to IT server ?
Format of data:
YYYYMMDD065959.dsk.log

currently both are loaded together. Need to separate them as above format.
Thanks in advance.
