Code:
$ temp=/u/ppattusa/unix
$ echo ${temp%${temp##*/}}
 
OUTPUT
/u/ppattusa/

pls see the above example, temp having some path and and the substitution will return the base path.

I think to pass the path as parameter they used like that. If you provide the script1 code sample, then it will be easy to find for wat purpose they using like that.

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. SEE ALSO
