出？可能是因为手册页遵循的是一种标准化、结构化且经过时间考验的格式，而
Texinfo
采用的形式更为自由。
如果你不喜欢
info
，还有别的
Texinfo
浏览器和转换工具，如
pinfo
、
info2www
、
tkman
，
甚至是
info2man
（先转换成
POD
，再转换成手册页格式）。

批量解压
ZIP
文件
17.3.1
问题
你想一次性解压目录下的多个
ZIP
文件，但
unzip *.zip
没有效果。
17.3.2
解决方案
将模式放入单引号即可，不同于其他大多数
Unix
命令，
unzip
自己处理文件通配模式。
unzip '*.zip'
也可以用循环来解压各个文件。
for
x in /path/to/date*/name/*.zip;
do
unzip "$x";
done
或者：
for
x in
$(
ls /path/to/date*/name/*.zip 2>/dev/null
)
;
do
unzip $x;
done
17.3.3
讨论
和很多
Unix
命令（如
gzip
和
bzip2
）不同，
unzip
的最后一个参数并不是任意长度的文
件列表。在处理命令
unzip *.zip
时，
shell
会扩展其中的通配符，因此（假设你有若干文
件，文件名分别为
zipfile1.zip
到
zipfile4.zip
），
unzip *.zip
会扩展为
unzip zipfile1.zip
zipfile2.zip zipfile3.zip ...
