如何解压一个我不知道路径的目录?我只知道目录名称。
我知道如何使用通配符解压单个文件:tar -xf somefile.tar.gz --wildcards --no-anchored 'index.php'
答案1
我只会通过两次:
$ tar -tf somefile.tar.gz | grep dir-i-am-looking-for | head -1
./foo/bar/dir-i-am-looking-for/somefile/bla/bla/bla
$ tar -xf somefile.tar.gz ./foo/bar/dir-i-am-looking-for
我在 GNU tar 中没有看到“通配符包含”选项。

一种使用方法perl
:
内容脚本.pl:
use warnings;
use strict;
use Archive::Tar;
## Check input arguments.
die qq[perl $0 <tar-file> <directory>\n] unless @ARGV == 2;
my $found_dir;
## Create a Tar object.
my $tar = Archive::Tar->new( shift );
## Get directory to search in the Tar object.
my $dir = quotemeta shift;
for ( $tar->get_files ) {
## Set flag and extract when last entry of the path is a directory with same
## name given as argument
if ( ! $found_dir && $_->is_dir && $_->full_path =~ m|(?i:$dir)/\Z|o ) {
$found_dir = 1;
$tar->extract( $_ );
next;
}
## When set flag (directory already found previously), extract all files after
## it in the path.
if ( $found_dir && $_->full_path =~ m|/(?i:$dir)/.*|o ) {
$tar->extract( $_ );
}
}
它接受两个参数,第一个是 TAR 文件,第二个是要提取的目录。像这样运行它:
perl script.pl test.tar winbuild
