我将如何制作一个可以在
sh我最接近的是：
extract_archive () {
printf '<archive_contents>' | tar -C "$extract_dir" -xvf -
}
其中
<archive_contents>%'\有没有更好的方法来做到这一点，这样就不需要转义？
（请不要指给我
sharmakeself替代方案是使用 shell 脚本结尾标记并使用 sed 剪切 shell 脚本本身。
脚本
selfextract.sh#!/bin/bash
sed '0,/^#EOF#$/d' $0 | tar zx; exit 0
#EOF#
使用方法：
# create sfx
cat selfextract.sh data.tar.gz >example_sfx.sh
# unpack sfx
bash example_sfx.sh
由于 shell 脚本不是编译的，而是逐条执行的，因此您可以使用如下模式混合二进制和文本内容（未经测试）：
#!/bin/sh
sed -e '1,/^exit$/d' "$0" | tar -C "${1-.}" -zxvf -
exit
<binary tar gzipped content here>
您可以将这两行添加到几乎任何 tar+gzip 文件的顶部，以使其可自解压。
测试：
$ cat header.sh
#!/bin/sh
sed -e '1,/^exit$/d' "$0" | tar -C "${1-.}" -zxvf -
exit
$ tar -czf header.tgz header.sh
$ cat header.sh header.tgz > header.tgz.sh
$ sh header.tgz.sh
header.sh
有关如何做到这一点的一些好文章可以在以下位置找到：
是的，您可以使用
xtarxtarcc contrib/xtar.c -o ./xtar
将
xtaryourTar.xtarcp ./xtar yourTar.xtar
将
yourTar.taryourTar.xtarcat yourTar.tar >> yourTar.xtar
chmod +x yourTar.xtar
