改路径untar?

lingam

有tar 文件内容路径是/etc/passwd
untar 会覆盖本机的/etc/passwd. 有没有办法untar 去其他路径。?

gnu tar的缺省行为是帮用户去掉/的，除非你使用-P显示指定使用绝对路径

版主，是SunOS, 没有Gnu tar.

呵呵，如果这样，俺能想出的方法就只有两个了
一种：chroot
另一种是装个gnu tar

1 WINRAR

Usage: /usr/local/bin/untar [options] archive.tgz [filename] ...
   or: /usr/local/bin/untar [options] -d filename.gz ...

Options: -t   Test -- list contents but don't extract
         -f   Force -- allow existing files to be overwritten
         -q   Quiet -- suppress the normal chatter
         -v   Verbose -- output extra information about each file
         -p   Path -- allow absolute pathnames (don't strip leading '/')
         -c   Convert -- convert files to local text format
         -d   Decompress -- perform "gunzip" but not "tar x"
         -n   No-name -- with "-d", ignore original name in gzip header

This program lists/extracts files from a "*.tar" or "*.tgz" archive.  You can
optionally specify certain files or directories to list/extract; otherwise it
will list/extract them all.  File attributes are preserved, and linked files
will be restored as links.  This program can also be used (with -d) to gunzip
non-tar files.

THIS PROGRAM IS IN THE PUBLIC DOMAIN, AND IS FREELY REDISTRIBUTABLE.
