Format the output of a hash table in Powershell to output to one line
hashtable, powershell
Solution
You can iterate over the keys of a hash table, and then in the loop lookup the values. By using the pipeline you don't need an intermediate collection:
($hashErr.Keys | foreach { "$_ $($hashErr[$_])" }) -join "|"
Problem
Is it possible to format the output of a hashtable in Powershell to output all the values onto one line? e.g. I have the hash table $hashErr with the below values: ``` $hashErr = @{"server1" = "192.168.17.21"; "server2" = "192.168.17.22"; "server3" = "192.168.17.23"} ``` Which are written to a log with the below: ``` $hashErr.GetEnumerator() | Sort-Object Name | ForEach-Object {ForEach-Object {"{0}`t{1}" -f $_.Name,($_.Value -join ", ")} | Add-Content $log ``` The will cause the below to be written to the log: ``` Name Value ---- ----- server2 192.168.17.22 server1 192.168.17.21 server3 192.168.17.23 ``` My question is, how can I format this hash table so the output is written all to one line, like the below? ``` server2 192.168.17.22 | server1 192.168.17.21 | server3 192.168.17.23 ``` This could be done by looping through all the values in the hash table and putting them into an array but surely there is a more direct way?
