Top Forums UNIX for Dummies Questions & Answers modifying ls() to support the display of file sequences? Post 302336707 by Corona688 on Wednesday 22nd of July 2009 03:46:51 PM

Guessing reliably when files are sequences and when they are not is no simple task with all the different ways files get labelled. When you see file32, should it expect a file01-fileXX, file05-fileXXX, file1-fileXXX, file5-fileXXX, or file00-fileXX, or... And should this be ambiguous, what should it default to? Always leading zeroes, always no leading zeroes, always the most digits, always clean sequences, the sequences with the longest run of files...

I haven't found a method yet that doesn't generate false positives and negatives, hence why I doubt it would get built into ls if someone did, since ls is supposed to produce clear, accurate information.

NAME
PX_timestamp2string -- Convert paradox timestamp into formated string SYNOPSIS
#include <paradox.h> char * PX_timestamp2string(pxdoc_t *pxdoc, double timestamp, const char *format) DESCRIPTION
Creates a string representation of a paradox timestamp as specified in the parameter format. The timestamp must be either retrieved with PX_get_data_double(3) after calling PX_get_record(3) or by simply using the double value in the pxval_t struct as returned by PX_retrieve_record(3). A timestamp contains both time and date information. The format string contains chars which stand for certain values of the date/time. The following table lists all available characters with a meaning. All other characters are being copied unmodified to the output string. If a special character shall not be interpreted it must be preceded with a backslash. Characters and their meaning in date/time format string Character Meaning Y year, numeric, 4 digits y year, numeric, 2 digits m month, numeric n month, numeric, no leading zeroes d day of the month, numeric j T{ day of the month, numeric, no leading zeros T} H hour, numeric, 24 hour format h hour, numeric, 12 hour format G T{ hour, numeric, 24 hour format, no leading zeroes T} g T{ hour, numeric, 12 hour format, no leading zeroes T} i minutes, numeric s seconds, numeric A AM/PM a am/pm L boolean for leap year RETURN VALUE
Returns pointer to string on success and NULL on failure. SEE ALSO
