Questions about the use of line continuation (\) together with inline comments (# comment) in shell scripts is a somewhat frequent topic on Unix and Linux forums. Unfortunately, there is no simple elegant solutions available for any of the standard shells such as bash, ksh93, zsh or the POSIX shell. Consider the following simple shell script: #!/bin/ksh93 find ./ \ -type f \ -name “*.pyc” Suppose you want to add comments describing each argument to the find utility.

This post describes the role of the BCD store in booting Windows 10 on a UEFI-based platform.

As expected CTP3 builds on the new technology provided in CTP2 which was released in May 2008. You can download CTP3 from the Microsoft Download Center. Hemant Mahawar, Program Manager for PowerShell, summarized the CTP3 release as follows: This release brings, among other things, performance improvements … things will be faster/more efficient than before. PowerShell remoting now allows implicit remoting where command execution appears to be local Microsoft’s PowerShell is radically different than shells on UNIX or GNU Linux systems in that Powershell can deal in objects rather than just plain text. A concrete example may help you more quickly understand the difference. Suppose you want to get and save information about all the files in a certain subdirectory. We want to get not only the names of the files but as much metadata as possible relating to each file such as date of creation, date of modification, etc. This information also needs to be stored in a single XML document.
