I've tried a ton of different variations of this, but I can't get it to work. I am trying to run mysqldump to export a database (in this case called global).
PS C:\Users\Administrator> &"$mysqlpath\mysqldump.exe -u$mysqluser -p$mysqlpass --databases global | Out-File $env:TEMP\database_backup\global_$timestamp.sql -Encoding UTF8"
& : The term 'C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqldump.exe -ubackup -pbackup_password --databases global | Out-File C:\Users\ADMINI~1\AppData\Local\Temp\2\database_backup\global_2013-12-11T11:47:28.sql -Encoding UTF8' is
not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (C:\Program File... -Encoding UTF8:String) [], CommandNotFoundException

It looks like it is being exploded into the proper variable names, but I can't get it to run.
UPDATE: So that was the right answer, I had a : in the timestamp. My other problem was solved by putting the variables inside double quotes (")
You are telling Powershell to run an EXE named
&"$mysqlpath\mysqldump.exe -u$mysqluser -p$mysqlpass --databases global | Out-File $env:TEMP\database_backup\global_$timestamp.sql -Encoding UTF8"
So remove the quotes (") and try again. Like so,
& $mysqlpath\mysqldump.exe -u$mysqluser -p$mysqlpass --databases global | Out-File $env:TEMP\database_backup\global_$timestamp.sql -Encoding UTF8

I wrote a script that supposed to change a certain word in a text file to the name of another file that has been dragged and dropped on onto it.
The drag and drop and recognition of the filename work without any issue.
When trying to write the file with PowerShell there is always an error message popping up.
powershell -Command "(Get-Content "%TemplatePath%").replace("[NAME]","!item_%%n!") | Out-File -encoding ASCII "!item_%%n!".txt"
the error messagethat pops up is
At line:1 char:79
... Templates\master.txt).replace([NAME],D:\Temp ...
Missing expression after ','.
At line:1 char:79
... Templates\master.txt).replace([NAME],D:\Temp ...
Unexpected token 'D:\Temp' in expression or statement..
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingExpressionAfterToken
Ok. I found the solution to the issue.
powershell -Command "(Get-Content \"%TemplatePath%\").replace(\"[NAME]\",\"!item_%%n!\") | Out-File -encoding ASCII \"!item_%%n!\".txt"
However, the problem is now that the if I use ASCII the single-quote in Don't is converted into an ? and looks like Don?t.
Using UTF8 works but the problem is its UTF8 with BOM.
And the program that I use to open the files does not work with BOM.
Is there any way to change the UTF8 BOM to UTF8 or to fix the ' to ? cenovertion?
I employ a user-defined function, called searchfor, from a PowerShell console prompt (Run as Administrator) to find files containing strings:
PS repo> gc Function:\searchfor
param([string]$root, [string[]]$includeexpression, [string]$regexp)
$fullpath = convert-path $root
Get-ChildItem -force -recurse $fullpath -include $includeexpression | Select-String $regexp
This has recently started to fail on some files with the following "cannot be read/access denied" error message:
Select-String : The file C:\builds\repo\LightweightSerialization\LightweightSerializationWriter.cs cannot be read: Access to the path 'C:\builds\repo\LightweightSerialization\LightweightSerializationWriter.cs' is denied.
At C:\Users\schlagermeier\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:174 char:71
+ ... recurse $fullpath -include $includeexpression | Select-String $regexp
+ ~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Select-String], ArgumentException
+ FullyQualifiedErrorId : ProcessingFile,Microsoft.PowerShell.Commands.SelectStringCommand
An attempt to read the file interactively with Get-Content fails with the same error. However, if I launch a Command Prompt (cmd.exe), also using Run as Administrator, I can read the file content with the type command.
I've looked at the file's permissions and acl, and it doesn't appear any different to others in the same folder which can be read by PowerShell. Can anybody suggest any possible causes and how these might be identified and fixed?
To change the extension of files located at: C:\Users\mohit singh\Desktop\spotlight, I typed the following command in the PowerShell
C:\Users\mohit singh\Desktop\spotlight> ren *.* *.jpg
But I get the following error:
ren : Cannot process argument because the value of argument "path" is not valid. Change the value of the "path"
argument and run the operation again.
At line:1 char:1
+ ren *.* *.jpg

You're trying to use the ren command from within PowerShell. However, ren in Powershell is an alias to Rename-Item which is a different command. Powershell and cmd are different shells that use different command interpreters.
Your simplest option is just to run your command from a cmd window, instead of Powershell.
But if you wanted to use Powershell, you can do this by getting every file in the current folder, piping it to Rename-Item, then using the ChangeExtension .Net API to change its extension (which is safer than simple string replacement).
Get-ChildItem -File | Rename-Item -NewName { [io.path]::ChangeExtension($_.Name, "jpg") }
If you want to act on subfolders too, add -Recurse to Get-ChildItem.
I have an application log for which I am trying to write a batch file that will tail the log and return strings that contain "queue size" so that the updating queue size can be displayed. Basically the Windows equivalent of:
tail -f app.log | grep "queue size"
From what I've read I would need to use Windows powershell. I have devised the following script:
powershell -command Select-String -Path C:\logs\app.log -Pattern "queue size"
This gives me the following error:
Select-String : A positional parameter cannot be found that accepts
argument 'size'. At line:1 char:1
+ Select-String -Path C:\logs\app.log -Pattern queue size
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Select-String], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SelectStringCommand
Although this as it stands doesn't work, would it constantly update with the current logic?
No, the PowerShell command will not continue to read the log as it's being updated. PowerShell can't really handle this task, so you'd be better off grabbing a Windows port of the Unix tail command (e.g. from GnuWin32 or UnxUtils) and use it with the batch find command:
tail -f C:\path\to\app.log | find "queue size"
You need to wrap the command in double quotes and use single quotes for the pattern:
powershell -command "Select-String -Path C:\logs\app.log -Pattern 'queue size'"
this should do:
cat c:\path\to\app.log -tail 100 -wait | select-string "queue size"
cat is an alias for Get-Content...
The -wait parameter will make it wait for log updates.
I'm trying to copy a list of files from a txt file and as a newbie, I'm having a hard time.
Here is a bit of the text file. The real file has no extra lines, but I had to do that to :
"D:\Shared\Customer Care\Customer Care Common\Customers Contracted\Customers Contracted\Fred 44705"
"D:\Shared\Customer Care\Customer Care Common\Customers Contracted\Customers Contracted\Johnson 47227"
"D:\Shared\Customer Care\Customer Care Common\Customers Contracted\Customers Contracted\Daniel 35434"
"D:\Shared\Customer Care\Customer Care Common\Customers Contracted\Customers Contracted\Frank, John 48273"
I've tried enclosing the filename string in double-quotes as well.
Here's the simple script I'm trying to use:
Get-Content c:\users\scripts\files-to-fix.txt | Foreach-Object {copy-item $_ d:\junk}
The error I'm getting is:
Copy-Item : Cannot find drive. A drive with the name ''D' does not
exist. At C:\users\mhyman\scripts\copyfiles.ps1:2 char:81
+ Get-Content c:\users\mhyman\scripts\files-to-fix.txt |
Foreach-Object {copy-item <<<< $_ d:\junk}
+ CategoryInfo : ObjectNotFound: ('D:String) [Copy-Item],
DriveNotFoundException
+ FullyQualifiedErrorId :
DriveNotFound,Microsoft.PowerShell.Commands.CopyItemCommand
I know this is simple, but I would really appreciate some help.
I think it is the surrounding quotes that are causing the problem ( as indicated by the error saying that a drive of name "D is not found. Try this:
get-content c:\users\scripts\files-to-fix.txt | %{ copy-item $_.trim('"') d:\junk}
Of course, if you can control the txt file, enter the list without the quotes.
By your tags and drive letters and backslashes it is clearly a Windows environment your working in and although I'm not a PowerShell scripter, I'm a better than most batch scipter and use a For / If conditioanla statement sicne it is shorter and you feed it your file instead of parsing out the file into reduudc commands on a line, so in your example:
for /F %%t in (the text file.txt) do copy /q %%t d:\junk
And then you go home and never worry about until the next morning
Does powershell have a runas ornative mode that can parse older, more proven and stable DOS commands ?
