Re: panel.sh modification suggestion (faster (once a second) clock update)

Hi, I apologize for my erroneous allegations. The problem was indeed on my side. I should have studied the code more before writing to this mailing list. I have, therefore corrected my mistake. Your mail has been of great help to me in doing so. Your suggestion of a problem with fflush() was correct. As it turns out, Debain's MAWK behaves different from GAWK in the way it handels buffers (*). I have no knowledge about buffers, and therefore do not understand the tecnical side of the issue. Yet I read about an option that makes MAWK behave in the way expected. So by changing line 44:

    awk '$0 != l { print ; l=$0 ; fflush(); }' "$@"

with:

    awk -W interactive '$0 != l { print ; l=$0 ; fflush(); }' "$@"

the problem gets fixed.

Some information about my MAWK version:


rafcloesen _at_ RafCloesen:~$ mawk -W version
mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan

compiled limits:
max NF             32767
sprintf buffer      1020

Description: a pattern scanning and text processing language
 Mawk is an interpreter for the AWK Programming Language. The AWK language is useful for manipulation of data files,
 text retrieval and processing, and for prototyping and experimenting with algorithms. Mawk is a new awk meaning it
 implements the AWK language as defined in Aho, Kernighan and Weinberger, The AWK Programming Language,
 Addison-Wesley Publishing, 1988. (Hereafter referred to as the AWK book.) Mawk conforms to the POSIX 1003.2 (draft
 11.3) definition of the AWK language which contains a few features not described in the AWK book, and mawk provides
 a small number of extensions. 
 
 Mawk is smaller and much faster than gawk. It has some compile-time limits such as NF = 32767 and sprintf buffer =
 1020.
