Thanks a lot for your comments, Scrutinizer. Those are all very valid points.
While writing the script, the biggest source of my consternation was the repetition of this construct
in lines 19 and 21.
I would've loved to do this:
1) Extract the 2nd token from the line and assign it to a temp variable and check if $temp is greater than $min.
2) If comparison test is true, i.e. $temp is greater than $min, then assign the $temp to max.
Some languages like C, Perl and (I think) Python allow this.
Kind of like this idiom in K&R, which accomplishes three things: fetch, assignment and comparison.
Your suggestion of using IFS along with the read function:

Does anyone have a script they would like to share that emulates "ls -lh" in ksh on Solaris 8?
Yeah, I know. Real men don't need that wimpy "h." Well, I'm a wimp. ;) (0 Replies)
Most shells flavors do not have associative arrays a.k.a. maps.
How would you emulate an associative array?
I had this problem once and found a working solution, but I don't want to spoil the game hence I wont tell it.
Wonder if anyone comes up with something better. (5 Replies)

It alows you to select steps you want and will then create a new script which includes only the steps you... (5 Replies)

ustrtok
ustrtok(3alleg4) Allegro manual ustrtok(3alleg4)NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok(char *s, const char *set);
DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be
searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always
copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the
same time). Example:
char *word;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok(temp, " -");
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok(NULL, " -");
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found.
