2003-07-10(usage): Use 1024*1024 in place of 1048576.Jim Meyering
2003-06-17(main): Call initialize_main.Jim Meyering
2003-05-21(elide_tail_lines_pipe): Fix a thinko.Jim Meyering
This sort of thing is why it'd be *Really Good* to factor out the common code used here and in tail.c.
2003-05-14(usage): Document new feature: --bytes=-N and --lines=-N.Jim Meyering
2003-05-14(AUTHORS): Enclose string in N_(...), now that it includes `and'.Jim Meyering
2003-05-13(elide_tail_lines_pipe): Don't apply cast to argument of free.Jim Meyering
2003-05-13(elide_tail_lines_pipe): Use `if', not an assert.Jim Meyering
Now that assert is no longer used, don't include <assert.h>.
2003-05-12Include <assert.h>.Jim Meyering
(AUTHORS): Add my name. (elide_tail_lines_pipe): New function.
2003-05-07Implement support so that `head --lines=-N' works on seekable files.Jim Meyering
(enum Copy_fd_status): Define. (COPY_FD_DIAGNOSE): New macro. (elide_tail_lines_seekable): New funtion. (elide_tail_lines_file): Call it here.
2003-05-03Extend head to accept --lines=-N (--bytes=-N) and to print allJim Meyering
but the N lines (bytes) at the end of the file. Include full-write.h, full-read.h, inttostr.h, quote.h. Use quote() in diagnostics, rather than literal `' marks. (copy_fd, elide_tail_bytes_pipe, elide_tail_bytes_file): New functions. (elide_tail_lines_pipe, elide_tail_lines_file): New functions. (head_file): Reorganize so as to call head from only one place. (main): Likewise, for head_file. Handle new, undocumented option, --presume-input-pipe. Handle negative line and byte counts.
2002-10-07(head_bytes, head_lines): Adapt to new safe_read ABI.Jim Meyering
2002-08-31Change `exit (0)' to `exit (EXIT_SUCCESS)',Jim Meyering
`exit (1)' to `exit (EXIT_FAILURE)', and `usage (1)' to `usage (EXIT_FAILURE)'.
2002-07-02(usage): Use the PACKAGE_BUGREPORT e-mail address, rather than hard-coding it.Jim Meyering
2002-02-16Include posixver.h.Jim Meyering
(usage): Document only the intersection of the old and new behaviors, to encourage portability. (main): Revert to previous behavior, except report an error and exit if the obsolete syntax is used and if conforming to the new standard.
2002-02-11(head_lines): If we have read too much data, tryJim Meyering
to seek back to the position we would have gotten to had we been reading one byte at a time. POSIX currently doesn't require this, but it's easy to do and some software relies on it.
2002-02-02Add more support for POSIX 1003.1-2001, which requires removal forJim Meyering
support of obsolete "-N" option syntax in expand, head, fold, split, tail, unexpand, uniq, and which prohibits options with optional arguments in od and pr. (usage): Document it. (main): Check for obsolete options. (header_mode_option): New constant.
2001-12-01Reflect renaming to, and new usage of these macros:Jim Meyering
HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.
2001-12-01(usage): Use new macros, EMIT_HELP_DESCRIPTION and EMIT_VERSION_DESCRIPTIONJim Meyering
instead of hard-coding --help and --version descriptions.
2001-11-23Factor out some common strings to make translation easier.Jim Meyering
Split usage strings so that --help and --version descriptions are alone in their own string. Likewise for the one that says: Mandatory arguments to long options are mandatory for short options too.
2001-11-11(usage): Split --help output into smaller pieces.Jim Meyering
Use fputs, not printf.
2001-11-04(usage): Say thatJim Meyering
``Mandatory arguments to long options are mandatory for short options too.\n\''
2001-10-27Give an accurate diagnostic when `head --bytes=30M' fails.Jim Meyering
(string_to_integer): Check explicitly for overflow, and lump everything else together as `invalid'.
2001-08-18(head_bytes): Read no more than the specified number of bytes.Jim Meyering
2000-08-07(head): Call write_header here.Jim Meyering
(head_file): ... not here.
2000-05-24(head_file): Use STDIN_FILENO in place of `0'.Jim Meyering
(main): Likewise.
2000-05-20Arrange to call close_stdout upon exit. Don't close stdout explicitly.Jim Meyering
2000-05-12(string_to_integer): Restrict base to 10.Jim Meyering
1999-04-24Include new "xstrtol.h", not "xstrtoul.h".Jim Meyering
Change all U_LONG_LONG to uintmax_t. (head_lines): Move a couple dcls into an inner scope. (string_to_integer): Rename from string_to_ull.
1999-04-04Standardize --help and --version processing.Jim Meyering
1999-04-03Use AUTHORS in place of string in parse_long_options call.Jim Meyering

1999-04-03Use PROGRAM_NAME in place of string in parse_long_options call.Jim Meyering
1999-04-03define PROGRAM_NAMEJim Meyering
1999-03-04Include long-options.hJim Meyering
[long_options]: Remove the "help" and "version" entries. Remove declarations of show_help and show_version. (main): Use parse_long_options, including author name(s). Remove the show_version and show_help blocks.

1999-01-14Don't prototype usage as static.Jim Meyering

Remove global variable, unit_size. (atou): Remove now-unused function. (parse_unit): Likewise. (string_to_ull): New function. (head): Take new parameter, count_lines. Use it instead of unit_size. Update callers. (head_file): Likewise. (main): Use string_to_ull, not atou/parse_unit.
