I know that I can use:
gc c:\FileWithEmptyLines.txt | where {$_ -ne ""} > c:\FileWithNoEmptyLines.txt
to remove empty lines. But How I can remove them with '-replace' ?
This question is related to
powershell
text-files
lines
I found a nice one liner here >> http://www.pixelchef.net/remove-empty-lines-file-powershell. Just tested it out with several blanks lines including newlines only as well as lines with just spaces, just tabs, and combinations.
(gc file.txt) | ? {$_.trim() -ne "" } | set-content file.txt
See the original for some notes about the code. Nice :)
