我有一个场景，我必须首先创建一个zip文件，然后，当我的文件从另一个位置到达时，它们将被添加到zip中。
第二部分使用-u参数完成：
zip -u {{project}}.zip {{file}}
该命令的--help也没有太大帮助：
user@host:~# zip --help
Copyright (c) 1990-2008 Info-ZIP - Type 'zip "-L"' for software license.
Zip 3.0 (July 5th 2008). Usage:
zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi list]
The default action is to add or replace zipfile entries from list, which
can include the special name - to compress standard input.
If zipfile and list are omitted, zip compresses stdin to stdout.
-f freshen: only changed files -u update: only changed or new files
-d delete entries in zipfile -m move into zipfile (delete OS files)
-r recurse into directories -j junk (don't record) directory names
-0 store only -l convert LF to CR LF (-ll CR LF to LF)
-1 compress faster -9 compress better
-q quiet operation -v verbose operation/print version info
-c add one-line comments -z add zipfile comment
-@ read names from stdin -o make zipfile as old as latest entry
-x exclude the following names -i include only the following names
-F fix zipfile (-FF try harder) -D do not add directory entries
-A adjust self-extracting exe -J junk zipfile prefix (unzipsfx)
-T test zipfile integrity -X eXclude eXtra file attributes
-y store symbolic links as the link instead of the referenced file
-e encrypt -n don't compress these suffixes
-h2 show more help
我已经用肮脏的方式完成了：
创建了一个名为emptyfile的文件，其中包含一个字节(空白(。
然后我将该文件添加到zip文件中：
zip -q {{project}}.zip emptyfile
最终删除：
zip -dq {{project}}.zip emptyfile
(如果省略-q，则会收到警告：zip warning: zip file empty(
通过这种方式，我得到了一个空的zip文件，可以-u更新。
所有这些都可以转换为oneliner(来自GaspardP的想法(：
echo | zip -q > {{project}}.zip && zip -dq {{project}}.zip -
有更优雅的方法吗？
