I always assumed they were identical in every way. ======================== Command Substitution Command substitution allows the output of a command to replace the command name. There are two forms: $(command) or ‘command‘ Bash performs the expansion by executing command and replacing the command substitution with the standard output of the command, with any trailing newlines deleted. ... *When the old-style backquote form of substitution is used, backslash retains its literal meaning except when followed by $, ‘, or \.* The first backquote not preceded by a backslash terminates the command substitution. When using the $(command) form, all characters between the parentheses make up the command; none are treated specially. ======================== Kenneth
