Useful git commands cheat-sheet

git commit --amend -m "New commit message"
git push origin --tags
git push --set-upstream origin name
git branch -u origin/foo - track remote branch
git remote -v - view list of remotes
git remote set-url origin - set remote
git branch -m newname - rename current branch

git push origin master -f - forced push

Rebase branch

git checkout feature/branch
git rebase master
git checkout master
git merge feature/branch // fast-forward here

Cleanup

git branch -D name - delete branch locally
git push origin --delete branchname or git push origin :branchname (:branchname should not exist locally then)git

git tag -d name - delete tag locally
git push origin :refs/tags/name - delete tag remotely

git reset --hard HEAD~1 - one commit back

git remote show origin (shows what is in origin and what is stale)
git remote prune origin (removes all local garbage from repo)
git branch -lvv (view list of branches with remotes and marks if remote gone)
git clean -df (remove all untracked files)
git checkout . (discard all the changes to tracked files)

Code snippet to investigate an object content without dances with debugger in C#

var investigated = ...; // assign your object here
System.IO.File.WriteAllText(
    @"D:\test.json",
    Newtonsoft.Json.JsonConvert.SerializeObject(
        investigated, 
        new Newtonsoft.Json.JsonSerializerSettings
        {
            Formatting = Newtonsoft.Json.Formatting.Indented,
            TypeNameHandling = Newtonsoft.Json.TypeNameHandling.Objects
        }));

Rethrow exception and preserve stack trace in.net 4.5

ExceptionDispatchInfo.Capture(myException).Throw();

Simplified module loading in powershell

There is a feature for automatic module discorvery in Powershell. It can search for modules based on paths from PsModulePath variable. It is easy to modify it in a script:

$env:PsModulePath += ";$PsScriptRoot/Modules"

Import-Module SomeModule -ArgumentList "foo" -Verbose // no need to specify path to the module

Get-OtherModuleThing // module will be loaded automatically

External program execution handling in Powershell

External command handling in Powershell is quite similar to .cmd-files. For example:

svn update
if ($lastexitcode -ne 0) { throw $lastexitcode }

UPD: it is better to use throw in powershell rather than exit

Proper script inclusion in PowerShell

It is handy to use simple script inclusion in PowerShell called dot sourcing:

. .\include.ps1

There is a problem however. If you try to call the script from another directory that script lives in, an error occurs. include.ps1 will not be found since PowerShell uses current folder by default as a starting point.
To avoid this, script directory can be used:

$scriptDirectory = Split-Path -parent $MyInvocation.MyCommand.Definition
. $scriptDirectory\include.ps1

UPD: In newer versions script directory variable is provided on the shelf, just use $PsScriptPath variable
