How can I get the number of bytes in a newline from PowerShell?



DOS/Windows newline is two (2) bytes, 0x0D0A.
UNIX/Linux newline is one (1) byte, 0x0A.
Mac newline is one (1) byte, 0x0D.



How can I write code to find the length of a newline on each platform? Output on Windows will produce two (2) bytes, but output on Linux will produce one (1) byte. I did not find anything related to this in about_Special_Characters.


about_Special_Characters



On Windows:


PS C:srct> type .nl.ps1
'`n'
'`n'.Length
"`n"
"`n".Length



Both Windows and Linux return the same result.


PS C:srct> .nl.ps1
`n
2


1

.NET Standard has an API for that, and is a always available from Powershell:


[system.environment]::newline.length



On Windows


PS C:Usersdbrowne> [system.environment]::newline.length
2



On Ubuntu


PS /home/dbrowne> [system.environment]::newline.length
1

PySpark count values by condition

Image
Clash Royale CLAN TAG #URR8PPP PySpark count values by condition I have a DataFrame, a snippet here: [['u1', 1], ['u2', 0]] basically one string ('f') and either a 1 or a 0 for second element ('is_fav'). What I need to do is grouping on the first field and counting the occurrences of 1s and 0s. I was hoping to do something like num_fav = count((col("is_fav") == 1)).alias("num_fav") num_nonfav = count((col("is_fav") == 0)).alias("num_nonfav") df.groupBy("f").agg(num_fav, num_nonfav) It does not work properly, I get in both cases the same result which amounts to the count for the items in the group, so the filter (whether it is a 1 or a 0) seems to be ignored. Does this depend on how count works? count 1 Answer 1 There is no filter here. Both col("is_fav") == 1 and col("is_fav") == 0) are just boolean expressions and count doesn't really care about their value as long a...
