OFS

suggest change

Variable called Output Field Separator contains string value that is used when converting an array to a string. By default $OFS = " " (a space), but it can be changed:

PS C:\> $array = 1,2,3
PS C:\> "$array" # default OFS will be used
1 2 3
PS C:\> $OFS = ",." # we change OFS to comma and dot
PS C:\> "$array"
1,.2,.3

Found a mistake? Have a question or improvement idea? Let me know.
