Talk:Command substitution

$ syntax
Bash-1.14.7, in documentation/features.info, descibes $ as "The Posix and ksh-style $ form of command substitution". I can't find any earlier version to check (1.14.17 was released in 1995, or thereabouts), though $ was introduced to ksh in ksh88 (presumably released in 1988, but I can't find anything with a casual search that states that rather than just implies it by the numbering). &mdash;Korath (Talk) 08:43, 11 March 2010 (UTC)
