查找工具/脚本/子目录

Question

有人知道我在Ubuntu上哪里可以找到此文件吗？

Answer 1

On my machine it's in:

/usr/share/doc/python2.7/examples/Tools/scripts/diff.py

However, it'll vary a little depending on your distrib and how up to date you are. But there's a really handy little tool called 'locate' that you can use to quickly find stuff on your machine.

locate diff.py | grep Tools

Gives me

/usr/share/doc/python2.7/examples/Tools/scripts/diff.py
/usr/share/doc/python2.7/examples/Tools/scripts/ndiff.py
/usr/share/doc/python3.1/examples/Tools/scripts/diff.py
/usr/share/doc/python3.1/examples/Tools/scripts/ndiff.py

As I have two versions of Python installed. I put it through grep, as sometimes locate can match quite a lot.

If you're sure that you have a file on your machine, but locate isn't finding it, you might need to update your database, which is done with the 'updatedb' command, as root. So, just run

sudo updatedb

and get a coffee (or two if you have a slow machine/very full drive) and then try again.

Answer 2

This command

  $ locate "Tools/scripts/diff.py"

will find the location of the file if it's installed. This depends on the database generated regularly by the updatedb command (this usually runs as a cron job, but can also be invoked manually)

FWIW, I just checked my Ubuntu installation (10.04LTS) and didn't find it. Perhaps only Python versions 2.7+ have this (the default version that came with this install is still v2.6.5)

Answer 3

I needed to know this for a different environment, namely Linux running an Amazon Machine Image (AMI). I installed Python 3.5 via "yum" but couldn't find the Tools/scripts directory using find/locate, etc., or any other "yum" package which included it.

So in the end I cloned the python source tree mirror:

git clone https://github.com/python-git/python python

This downloads the Tools/scripts folder which I then moved to some standard location. I needed the "2to3" program from "scripts" and this worked. There is also a "clone or download" link at that URL where the package can be downloaded in the usual way if git is not available.

I couldn't find an easy way to install the Tools/scripts via "yum" on AMI Linux, which would still be my preference.
