Two ways to change:

$web = Get-SPWeb http://peakfinders
$list = $web.Lists["Employee"]
$list.fields | select Title, InternalName, Hidden, CanBeDeleted | sort title | ft -AutoSize

As you will most often be interested in the non-hidden fields, you can add a Where to filter them:

$list.fields | select Title, InternalName, Hidden, Sealed, CanBeDeleted | where {$_.Hidden -eq $false} | sort title | ft –AutoSize

# create the FtpWebRequest and configure it
$ftp = [System.Net.FtpWebRequest]::Create("ftp://peakfinder/logome.png")
$ftp = [System.Net.FtpWebRequest]$ftp
$ftp.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$ftp.Credentials = new-object System.Net.NetworkCredential("peak","peak@123")
$ftp.UseBinary = $true
$ftp.UsePassive = $true
# read in the file to upload as a byte array
$content = [System.IO.File]::ReadAllBytes("C:\me.png")
$ftp.ContentLength = $content.Length
# get the request stream, and write the bytes into it
$rs = $ftp.GetRequestStream()
$rs.Write($content, 0, $content.Length)
# be sure to clean up after ourselves
$rs.Close()
$rs.Dispose()

In this post we have creating custom action url in testEmployee list
Please see the below script

Add-PSSnapin "Microsoft.Sharepoint.Powershell"
 $site = "https://sharepointqa/"
 $web = Get-SPWeb $site
 $list = $web.Lists["testEmployee"]
 $customAction = $list.UserCustomActions | Where-Object {$_.Title -eq "New Entry"}
 Write-Host $customAction -f "blue"
 $customAction.Url = "https://peakfinders.blogspot.com"
 $customAction.Update();

We have facing this issue unable to display webpart.

When we have create more than 120 columns in our list Its shows error in our page

Default setting is 1 second. The PowerShell code below changes it to 2 seconds which should be sufficient for your farm.  So,we will choosing 4 seconds timeout. 



Powershell Script:

$farm = Get-SPFarm
$farm.XSLTTransformTimeout = 4
$farm.Update()



Effects:

If you backup/restore a site collection, you get this error when displaying All Items views.
I created a view loading 20 items at a time instead of all and it fixed the issue.

 Add-PSSnapin Microsoft.SharePoint.PowerShell


 Export-SPWeb "http://raghu/sites/test/test1" –Path "C:\rm.cmp" -includeusersecurity

 Import-SPWeb "http://raghu/sites/test/test1" -path "C:\rm.cmp" -IncludeUserSecurity

$web = Get-SPWeb "http://spserver/sites/Raghu/"
$web.AllProperties["SaveSiteAsTemplateEnabled"] = "true"
$web.Update()
