Creating command line alias with python

由 送分小仙女□ 提交于 2019-12-07 05:02:21
问题 I want to create command line aliases in one of my python scripts. I've tried os.system(), subprocess.call() (with and without shell=True), and subprocess.Popen() but I had no luck with any of these methods. To give you an idea of what I want to do: On the command line I can create this alias: alias hello="echo 'hello world'" I want to be able to run a python script that creates this alias for me instead. Any tips? I'd also be interested in then being able to use this alias within the python

What type of scope does Haskell use?

由 感情迁移 提交于 2019-12-07 03:26:52
问题 I'm trying to figure out if Haskell uses dynamic or static scoping. I realize that, for example, if you define: let x = 10 then define the function let square x = x*x You have 2 different "x's", and does that mean it is dynamically scoped? If not, what scoping does it use, and why? Also, can Haskell variables have aliases (a different name for the same memory location/value)? Thanks. 回答1: There are some things wrong in your statements... There are no mutable variables in Haskell just

querying for dns aliases

由 送分小仙女□ 提交于 2019-12-07 02:19:57
问题 I found some code from the msdn site (Code included below), which looks like it will return all dns aliases for a given server. I've implemented the code in a cosole app, which should allow me to enter the host name of a server and it should return all dns alias names. I enter the host name of a server in our domain known to have aliases (I can ping the host and the aliases and they all resolve to the same IP), but this code does not find the alias names. Obvously my understanding of dns

When is it required to give a table name an alias in SQL?

问题 I noticed when doing a query with multiple JOINs that my query didn't work unless I gave one of the table names an alias. Here's a simple example to explain the point: This doesn't work: SELECT subject from items join purchases on items.folder_id=purchases.item_id join purchases on items.date=purchases.purchase_date group by folder_id This does : SELECT subject from items join purchases on items.folder_id=purchases.item_id join purchases as p on items.date=p.purchase_date group by folder_id

Invoking bash aliases in Fabric scripts

由 随声附和 提交于 2019-12-06 19:30:09
问题 I have aliases in a ~/.bash_aliases file on a remote ubuntu server. The file is loaded in the standard way from a ~/.bashrc file, like so: if [ -f ~/.bash_aliases ]; then . ~/.bash_aliases fi That ~/.bashrc file in turn is loaded (also in a standard way) from a ~/.profile file which looks like this: if [ "$BASH" ]; then if [ -f ~/.bashrc ]; then source ~/.bashrc echo ".profile loaded .bashrc" fi fi mesg n I've found that my aliases were unavailable in my fabric commands, e.g. when I do this

How to use apache mod_rewrite and alias at the same time?

问题 I have a directory outside the webroot that is used for storing images uploaded from a separate admin system. Images are stored in this format: filepath/writable/images/00/00/23/65/filename-236581.jpg (where the webroot is filepath/html) ...for example. Here, 236 is the ID of the image in the database, and the file system is broken into numbered directories to stop more than 100 inodes from being used within one directory. I want to be able to access these from the front-end webserver, like

PowerShell alias syntax for running a cmd.exe builtin function?

由 风格不统一 提交于 2019-12-06 12:09:39
As I have only recently switched to PowerShell from cmd.exe , I often find it convenient to do little things in a familiar way by calling cmd to do them. For instance, to do a 'bare' file listing this works great: PS> cmd /c dir /b dir1 dir2 file1.txt I'd like to make an alias for this but I can't figure out the right syntax. So far I've tried: PS> Set-Alias dirb cmd /c dir /b # error (alias not created) PS> Set-Alias dirb "cmd /c dir /b" # fail (alias doesn't work) PS> Set-Alias dirb "cmd `"/c dir /b`"" # fail (alias doesn't work) Any suggestions? I'm looking for a general solution to calling
