-The following is a list of LSMCD commands useable in telnet, each with a description, ​the command'​s ​syntax, an example of use (including user input and system output separated by an empty line), and an explanation of potentially confusing values. Note: in the syntax sections, values enclosed in <> indicate a required value while values enclosed in [] indicate an optional one.+The following is a list of LSMCD commands useable in telnet, each with a brief description. For more informationsee each command'​s ​page.
  
-===== get ===== +[[litespeed_wiki:​lsmcd:​commands:​get|get]] - Read the value tied to the user-provided key.
