From: Paul Eggert Date: Mon, 27 Aug 2001 14:41:56 +0000 (+0000) Subject: (ANCHORED_OPTION, IGNORE_CASE_OPTION, NO_ANCHORED_OPTION, X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=17afd0438f6d86686e9bc6df80e538b3201b889e;p=chaz%2Ftar (ANCHORED_OPTION, IGNORE_CASE_OPTION, NO_ANCHORED_OPTION, NO_IGNORE_CASE_OPTION, NO_WILDCARDS_OPTION, NO_WILDCARDS_MATCH_SLASH_OPTION, WILDCARDS_OPTION, WILDCARDS_MATCH_SLASH_OPTION): New enum values. (long_options, usage, decode_options): Add support for --anchored, --ignore-case, --no-anchored, --no-ignore-case, --no-wildcards, --no-wildcards-match-slash, --recursion, --wildcards, --wildcards-match-slash. (decode_options): Implement the new way of interpreting exclude patterns. (usage): --newer-mtime takes a DATE operand. DATE may be a file name. (OPTION_STRING, decode_options): Add -I, -y. Currently these options just print error messages suggesting alternatives. (add_filtered_exclude): Remove. --- diff --git a/src/tar.c b/src/tar.c index 0095701..69ec97c 100644 --- a/src/tar.c +++ b/src/tar.c @@ -1,5 +1,8 @@ /* A tar (tape archiver) program. - Copyright 1988,92,93,94,95,96,97,99,2000,2001 Free Software Foundation, Inc. + + Copyright 1988, 1992, 1993, 1994, 1995, 1996, 1997, 1999, 2000, 2001 Free + Software Foundation, Inc. + Written by John Gilmore, starting 1985-08-25.
