s3tar的Python项目详细描述
s3tar公司
从S3中提取（过滤）文件并将它们添加到tar存档中。在
创建命令行脚本star。在
$ star --help
Usage: star [OPTIONS] PATH
Generates a tar archive of S3 files.
Files are selected by a path made up of 'bucket/prefix' and optionaly by a
time-based and/or name filter.
'profile' is the AWS CLI profile to use for accessing S3. If you use
chaim or cca then this is the alias name for the account.
The time based filter relies on the files being named with ISO Formatted
dates and times embedded in the file names. i.e.
'file.2020-03-04T12:32:21.txt' The regular expression used is:
/.*[._-]{1}([0-9-]{10}T[0-9:]{8}).*/
The 'start' and 'end' parameters can either be ISO formatted date strings
or unix timestamps. If only the date portion of the date/time string is
given the time defaults to midnight of that day.
The length parameter is a string of the form '3h', '2d', '1w' for,
respectively 3 hours, 2 days or 1 week. Only hours, days or weeks are
supported. The 'length' and 'end' parameters are mutually exclusive, give
one or the other, not both.
If neither the 'end' nor the 'length' parameter is given, the end time
defaults to 'now'.
If the 'start' parameter is not given no time filtering of the files is
performed, and all files found down the path are copied across to the tar
archive recursively.
To use the last modified time stamp of the files rather than their names
for filtering pass the '-M' flag.
To use the name filter, pass in a partial string that object names must
contain.
The tar archive can be compressed using gzip, bzip2 or lzma. Defaults to
gzip. Pass a one char string to the `-c` option of "g", "b", "z" or "n".
"n" is no compression. The output tar archive will be named accordingly:
".tar.gz" for gzip, ".tar.bz2" for bzip2, ".tar.xz" for lzma and ".tar"
for no compression.
The output filename of the tar archive will be $HOME/<bucket name>.tar
You can change this with the "-o" option.
Using the "-q" switch will turn off all messages (except errors) apart
from the final output of the full path of the tar archive that is created.
Using the "-v" switch will make the program verbose, showing each file
that is copied into the tar archive.
Files in Glacier and Glacier Deep Archive are ignored.
Options:
-c, --compression TEXT optional compression ['b', 'g', 'n', 'z'], default
'g'
-e, --end TEXT optional end time
-l, --length TEXT optional time length (i.e. 1d, 3h, 4w)
-M, --usemodified use last modified time stamp rather than filename
for filtering
-N, --name TEXT optional name filter
-o, --output TEXT output file name (default: bucket name)
-p, --profile TEXT AWS CLI profile to use (chaim alias)
-q, --quiet be very quiet, only show the tar file name
-s, --start TEXT optional start time
-v, --verbose show files that are being copied
--help Show this message and exit.
安装
脚本仅限于python3（>；=python3.6）。在
将其安装在python3用户目录下：
^{pr2}$如果这是您拥有的第一个python3用户脚本，那么您必须进行调整
你的路。在Linux上，脚本位置将是$HOME/.local/bin
计算机，所以把它添加到shell init文件中的路径中
echo "export PATH=$HOME/.local/bin:$PATH" >>~/.bashrc
如果你的壳是重击。在
要检查安装是否正常：
star --help
