alias

问题 BACKGROUND: In the API I am porting, there are a large number of functions prefixed with sqlite3_. They are encapsulated in a class named Sqlite3, so the function call is Sqlite3.sqlite3_... I've created a number of alias calls, similar to the following, //C# alias for call public static void result_error_toobig(sqlite3_context pCtx) { sqlite3_result_error_toobig(pCtx); } //Native call public static void sqlite3_result_error_toobig(sqlite3_context pCtx) { Debug.Assert(sqlite3_mutex_held(pCtx

问题 Is it possible in PowerShell to create alias for path? For example: I have to write all time PS PS C:\Users\Jacek>cd C:\windows\microsoft.net\framework\v4.0.30319 I will happy if I could write PS PS C:\Users\Jacek>cd dotNet4path 回答1: You could just create a variable in your powershell profile with that path as the value. Then all you would need to do is something like cd $dotNet4path To add something to your profile profile, type $profile, into a powershell window and it will display the path

问题 How does one apply DirectoryIndex to an Alias in Apache without resulting in error 403? This results in response header 200: http://localhost/ Which presents http://localhost/index.html <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www DirectoryIndex index.html index.php index.xhtml index.htm default.htm <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny

问题 This alias in .git/config : pycat = !find -iname '*.py' -exec cat {} \; Gives me this in the shell: $ git pycat fatal: bad config file line 19 in .git/config I've tried quotes, no quotes, switching quote types, escaping everything up to four levels, but I can't figure out what's making git unhappy here. 回答1: A little farting around says it's the semicolon, pycat = !find -iname '*.py' -exec cat {} "\\;" pycat = !find -iname '*.py' -exec cat {} "';'" pycat = "!find -iname '*.py' -exec cat {} \\

问题 I'm attempting to use python to dynamically create bash aliases (like, for example, aliases to log in to a set of servers). I'd love to be able to do something like this: from subprocess import call SERVERS = [ ("example", "user@example.com"), #more servers in list ] for server in SERVERS: call('alias %s="ssh %s"' % (server[0], server[1]), shell=True) The problem is that subprocess launches the jobs in a separate shell session, so the program runs fine, but does nothing to the shell session I

问题 In Oracle, is there a way to select all the columns that are returned from a custom query with aliases? As an example, let's say we have a query as the following: SELECT FIRST_NAME AS COL1, LAST_NAME AS COL2, ADDRESS AS COL3 FROM PEOPLE I would like to know if an encapsulating query can be made that would return: COL1 COL2 COL3 回答1: Here is how to do it in PL/SQL. Don't know if it is possible with straight oracle SQL only. You could always encapulate it in some kind of function if needed.

问题 I need to view a specific line of a log file from time to time: $ head -10 log.txt|tail -1 # to view line 10 of log.txt Then I wrote a function v in my bashrc to make life easier: $ v 10 Ok, maybe I'm a little splitting hair here: I'd like to ignore the space too: $ v10 The only way I know is to define lots of alias: alias v1='v 1' alias v2='v 2' alias v3='v 3' alias v4='v 4' ... Is there any good way for this? Thanks @Chirlo and @anishsane for the idea. Here is my final version, based on

问题 I have a DigitalOcean droplet (i.e. a VPS server), with Ubuntu 14.04 and Apache 2.2. I had 4 virtualhosts configured, with 4 different domains pointing to 4 different folders, no problem. I needed to point a 5th domain (let's call it www.someshop.tld ) containing a PrestaShop installation. I added the following Alias to the apache2/sites-available/domain1.conf file so that www.domain1.tld/someshop would lead to www/prestashop , and it worked fine <VirtualHost *:80> ServerName www.domain1.tld

问题 When answering "Git pull hook script which executes locally", I stumbled upon the use-case to alias a built-in git command such as pull or push with an extension. How do I do that? First thought was: [alias] push = "!echo -n \"really push? [y/n]\";read -s -n 1 really;if [[ $really == \"y\" ]];then git push; else echo \"aborting\"; fi" This works fine as long as I don't name my alias push (for example qp or something like that). But as soon as I call it push , it's somehow ignored. Is there a

问题 Actually my query is like this : SELECT ABS(20-80) columnA , ABS(10-70) columnB , ABS(30-70) columnC , ABS(40-70) columnD , etc.. The pb is each ABS() is in fact some complex calculation , and i need to add a last columnTotal witch is the SUM of each ABS() , and i'd like to do that in one way without recalculate all . What i'd like to achieve is : SELECT ABS(20-80) columnA , ABS(10-70) columnB , ABS(30-70) columnC , ABS(40-70) columnD , SUM(columnA+columnB+columnC+columnD) columnTotal . The
