问题 I'd like to batch rename files in a folder, prefixing the folder's name into the new names. i.e. files in C:\house chores\ will all be renamed house chores - $old_name . 回答1: Option 1: Using Windows PowerShell Open the windows menu. Type: "PowerShell" and open the 'Windows PowerShell' command window. Goto folder with desired files: e.g. cd "C:\house chores" Notice: address must incorporate quotes "" if there are spaces involved. You can use 'dir' to see all the files in the folder. Using '|'

How to remove filename prefix with a Posix shell

由 六眼飞鱼酱① 提交于 2019-11-27 07:06:42
How can I remove the filename prefix in Bash as in the following example: XY TD-11212239.pdf to get 11212239.pdf i.e, remove XY TD- ? Shahbaz You have given very little information, but assuming you are doing this in bash, and have a list of files whose prefix needs to be removed, you can pipe the list through sed : For example: ./generate_your_list_of_files | sed -e 's/^prefix//' or if your list of files are space separated: echo TD-file1 TD-file2.x.yt TD-file3-beep | sed -e 's/\<TD-//g' The first one matches prefix in the beginning of the line and removes it. The second one matches TD- (or

What kind of prefix do you use for member variables?

由 走远了吗. 提交于 2019-11-27 07:05:32
No doubt, it's essential for understanding code to give member variables a prefix so that they can easily be distinguished from "normal" variables. But what kind of prefix do you use? I have been working on projects where we used m_ as prefix, on other projects we used an underscore only (which I personally don't like, because an underscore only is not demonstrative enough). On another project we used a long prefix form, that also included the variable type. mul_ for example is the prefix of a m ember variable of type u nsigned l ong. Now let me know what kind of prefix you use (and please

targetNamespace and xmlns without prefix, what is the difference?

由 无人久伴 提交于 2019-11-27 06:00:42
In an xml schema document, if I have both the targetNamespace and the xmlns without a prefix . <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://example.com/" xmlns="http://example.com/"> What is the exact difference between them? My comprehension is that if you have an xmlns without a prefix, all elements without prefix gets that namespace and...confusingly the same goes for targetNamespace. targetNamespace is an XML Schema "artifact"; its purpose: to indicate what particular XML namespace the schema file describes. xmlns - because the XML Schema is an XML

linux下升级4.5.1版本gcc

由 一曲冷凌霜 提交于 2019-11-27 02:33:18
1.背景：公司编译的服务器gcc版本非常老旧，还在使用4.1.2.由于一下新特性必须在4.2.0之后的版才支持编译。所以没办法只能升级。但是不能破环整体环境（因为其他人还需要依赖东东）。 2.首先需要下在一个gcc的版本，还有其依赖库，我这里是4.5.1的gcc 其他依赖的库分别是gcc-4.5.1.tar.gz gmp-6.1.0.tar.bz2 mpc-1.0.3.tar.gz mpfr-3.1.4.zip 3.首先安装gmp 因为他不需要依赖直接进去./configure --prefix=/xx/gmp;make clean;make -j8;make install 4.然后是装mpfr 因为他依赖gmp 进去./configure --prefix=/xx/mpfr --with-gmp=/xx/gmp;make clean;make -j8;make install 5.再装mpc 因为依前面gmp 和mpfr 两个东西，./configure --prefix=/xx/mpfr --with-gmp=/xx/gmp --with-mpfr=/xx/mpfr;make clean;make -j8;make install 6.再装gcc ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr

How can I strip namespaces out of an lxml tree?

问题 Following on from Removing child elements in XML using python ... Thanks to @Tichodroma, I have this code: If you can use lxml, try this: import lxml.etree tree = lxml.etree.parse("leg.xml") for dog in tree.xpath("//Leg1:Dog", namespaces={"Leg1": "http://what.not"}): parent = dog.xpath("..")[0] parent.remove(dog) parent.text = None tree.write("leg.out.xml") Now leg.out.xml looks like this: <?xml version="1.0"?> <Leg1:MOR xmlns:Leg1="http://what.not" oCount="7"> <Leg1:Order> <Leg1:CTemp id="FO

Check if one string is a prefix of another

由 末鹿安然 提交于 2019-11-27 00:57:07
问题 I have two strings which I'd like to compare: String and String: . Is there a library function that would return true when passed these two strings, but false for say String and OtherString ? To be precise, I want to know whether one string is a prefix of another. 回答1: Use std::mismatch. Pass in the shorter string as the first iterator range and the longer as the second iterator range. The return is a pair of iterators, the first is the iterator in the first range and the second, in the

Determine prefix from a set of (similar) strings

由 孤街浪徒 提交于 2019-11-27 00:48:09
I have a set of strings, e.g. my_prefix_what_ever my_prefix_what_so_ever my_prefix_doesnt_matter I simply want to find the longest common portion of these strings, here the prefix. In the above the result should be my_prefix_ The strings my_prefix_what_ever my_prefix_what_so_ever my_doesnt_matter should result in the prefix my_ Is there a relatively painless way in Python to determine the prefix (without having to iterate over each character manually)? PS: I'm using Python 2.6.3. Ned Batchelder Never rewrite what is provided to you: os.path.commonprefix does exactly this: Return the longest
