Unix tail -f equivalent in Windows PowerShell

One of my favorite ways of monitoring jobs from the Unix command line was to tail an output file using the -f switch.  This way I could see updates to my screen as they were written to the file.  It is a good progress indicator for jobs that are active:

tail -f filename.txt

I always wanted an equivalent command in Windows PowerShell, but I was unable to find it until a colleague of mine pointed me in the right direction this week.  The PowerShell syntax is:

get-content -Path “C:\filename.txt” -Wait

Now I monitor jobs just as well in Windows!  Thanks Will!

Find Failed Files in Robocopy

I copied 123 GB of data between two drives using Robocopy; over thirty-seven thousand files, with one failure.  My output log was over 2 MB!  Great!  How do I find this needle in the haystack?  All I want to do is find one failed file in my Robocopy output file.

I determined that searching for the word ERROR in the output file will find the rows in the log file indicating the reason for the failure.


New File           0 c:\Data\.lock 2012/09/28 10:50:37 ERROR 32 (0x00000020) Copying File c:\Data\.lock The process cannot access the file because it is being used by another process.

Print Screen with MacBook Pro

I run Windows 8 on my MacBook Pro, however there is no Print Screen key.  How do I take a screen shot (Print Screen) running Windows on MacBook Pro?

Take a screen shot (Print Screen) with: fn + Shift + F11

You can also capture the active window with: fn + Shift + Alt + F11

Don’t forget, you can also use the Snipping Tool .
