如何在 Ubuntu 中创建空的 zip 文件?

问题描述 投票:0回答:1

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。

第二部分是通过

-u
参数完成的:

zip -u {{project}}.zip {{file}}

--help
对于这个命令也不是很有帮助:

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

我用肮脏的方式做到了:

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

然后,最后删除它:

zip -dq {{project}}.zip emptyfile

(如果省略

-q
,您将收到警告:
zip warning: zip file empty

这样我就得到了一个空的 zip 文件,你可以在上面运行

-u
(更新)。


所有这些都可以转换为一行(GaspardP 的想法):

echo | zip -q > {{project}}.zip && zip -dq {{project}}.zip -

有更优雅的方法吗?
