Probably won't make it into 5.3, though. Ok, another issue, bsdtar shows archive type at the end of listing when -tvv specified, but gnu tar not shown: % tar tvvzf download/hcidump-1.5.tar.gz |& tail -n3 -rw-r--r-- 0 max max 8207 Aug 17 2003 hcidump/parser/sdp.h -rw-r--r-- 0 max max 3398 Feb 18 2004 hcidump/parser/hidp.c Archive Format: GNU tar format, Compression: gzip % gtar tvvzf download/hcidump-1.5.tar.gz | & tail -n3 -rw-r--r-- max/max 16065 Sep 13 03:38 2003 hcidump/parser/sdp.c -rw-r--r-- max/max 8207 Aug 17 02:05 2003 hcidump/parser/sdp.h -rw-r--r-- max/max 3398 Feb 18 01:33 2004 hcidump/parser/hidp.c % (Yes, know it is enough -tv to get such list, but I am always use -vv to get similar result in -t and -x cases) Archive information is not ls-like output at all: man tar ... -v Produce verbose output. In create and extract modes, tar will list each file name as it is read from or written to the archive. In list mode, tar will produce output similar to that of ls(1). Additional -v options will provide additional detail. ...
