To answer the question “is there any preference/difference”: Yes, there are as many preferences as there are opinions, but be careful whose preferences you adopt. As a best practice, it is advisable to write portable SQL if it doesn’t require any extra effort. For your specific sample, it is just as easy to write a … Read more
For git aliases, the autocomplete function for the git command (__git()) uses a call to git config –get “alias.$1” to determine that equivalent autocomplete function. This works for simple mappings but will choke on more complex aliases. To get around this, define an autocomplete function with a name that matches your alias, i.e. _git_tagarchive(). The … Read more
Apparently alias and try_files don’t work together. However, I don’t think you need to use alias. location /mr { default_type “text/html”; try_files /fullpath/$uri /fullpath/$uri.html /fullpath/$uri/index.html /fullpath/index.html; } Which would try: Exact file. File with .html added. Index in the path. Default index. I think the root directive does work with try files but am unable … Read more
Add a \ (backslash) before the command to disable the alias, like this: \ls This will invoke the original (un-aliased) ls. Example: $ ls #will invoke the alias total 0 -rw-rw-r– 1 dogbane foo 0 Nov 3 16:04 c -rw-rw-r– 1 dogbane foo 0 Nov 3 16:04 b -rw-rw-r– 1 dogbane foo 0 Nov 3 … Read more

Thereafter the program can use “f_ptr” and the selected function will be invoked. module ExampleFuncs implicit none contains function f1 (x) real :: f1 … Read more
using namespace new::nested; Example at Ideone. Or if you actually want a real alias: namespace on = one::nested; Example at Ideone.
Namespace alias in the class definition is illegal, as specified by the language specification. Its allowed in only in namespace scope or function scope. You can make an alias at the namespace scope. But this will create a permanent alias which can be used from other files as well. However, the solution is simple: you … Read more
The issue here is not with the sc executable. As the error states, sc resolves to Set-Content. If you issue Get-Alias -Name sc, you’ll see: To bypass the alias, use the full name of the executable (including the file extension): PS C:\> sc.exe query wuauserv SERVICE_NAME: wuauserv TYPE : 20 WIN32_SHARE_PROCESS STATE : 4 RUNNING … Read more
What you really want is a function, instead of an alias. pwd_alias() { echo “$PWD” } Aliases do nothing more than replace text. Anything with complexity calls for a function.
