Philip,
I'm finally having to give in and implement a string function to extract a
section from a token separated string - ie like getting components out of
a passwd line.
I was thinking of making this something like:-
${token{<field>}{<sep>}{<string>}}
where:-
<field> - numeric field id >= 0 (first field is zero)
<sep> - class of characters acting as separators (as in strtok(2)
or strchr(2))
<string> - string to parse
so in a passwd like line,
${token{5}{:}{<line>}}
would extract the home directory.
Are there any problems with this? Syntax/Name OK?? Any suggestions for a
better solution? etc...
Nigel.
