</sarcasm>? I would be much more likely to remeber ls | renamer than figure out how to write such a command.

  > </sarcasm>? Nope. > to remeber That's the point, you don't need to remember anything, it would come naturally after a day of tinkering with PS/pwsh. You just write it for your current needs. This example was just a quick one-liner, it's very simple: ls | % { # get the file list, cycle for each item rename-item # obvious usage: rename-item oldname newname $_ # pretty obvious, the source - place the loop variable here ie file name -newname # explicit calling for a parameter name, isn't really needed $( # subroutine start or eval if you prefer, to construct the new file name: # 'text' + (take property basename from the file and regex it) + 'text' 'myfile_' + ($_.BaseName -replace '\D') + '.md' ) # subroutine end } # cycle end. It could be simplified (in this example) to this: ls | % { $a = 'myfile_' + ($_ -replace '\D') + '.md' rename-item $_ $a } which could be even written as a one-liner if you prefer it right now, just add a semicolon after `$a = ...` ls | % {$a = 'myfile_' + ($_ -replace '\D') + '.md'; rename-item $_ $a }
