I have few files namely - "a.mov-, attachment", "b.mov-, attachment", "c.mov-, attachment",etc.. I want to trim the keyword: "-, attachment" from all files in that folder.

Please suggest me an approach which script will be best suited for this - AppleScript, Shell, Python etc. (I being a non-scripting guy).

Note: I m using MacOSX-Maverics[Terminal].

Using just the shell:

for f in *", attachment"; do
    mv "$f" "${f%, attachment}"
done

The form ${f%something} returns the value of the variable f with the text following the % removed from the end of the value.

$ var="hello world"
$ echo "${var%orld}"
hello w

If you put a glob pattern in there, the shortest match will be removed with ${var%pattern} and the longest match with ${var%%pattern}

$ echo "${var%l*}"
hello wor
$ echo "${var%%l*}"
he

If the pattern does not match the end of the string, nothing is removed

$ echo "${var%foo}"
hello world

you can use rename command if you're using linux:

rename 's/-, attachment//' *attachment

with a GUI, there is a lot of tools like ANT Renamer for example.

So, I see similar questions, but none of the answers work for me.

I updated Python to 3.1.3 from 2.6.1. Everything works, except: When I type python into Terminal, I get:

Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>

So, how do I change the version of Python that runs in the Shell? I've tried the script that they provide. It adds their directory to my $PATH, but it still doesn't change the version that'd displayed from Terminal. Here's what I get when I echo $PATH:

/Library/Frameworks/Python.framework/Versions/3.1/bin:/Library/Frameworks/Python.framework/Versions/3.1/bin:/Library/Frameworks/Python.framework/Versions/3.1/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

It appears that the script provided has added their directory for every time I ran the script (I tried it a few times, naturally).

Here's some caps of what is in the other relevant folders it mentions:

/Library/Frameworks/Python.framework/Versions/3.1/bin
