In almost all cases in this document, I use the $(<command>) convention for command substitution: that is, [Code: SOAP] .:: odesli.co ::. .:: www.pdc.edu ::.
$(date +%H%M) |
means "substitute the output from the date +%H%M command here." This works in Bash 2.0+. In some older versions of Bash, prior to 1.14.7, you may need to use backquotes ( .:: telegra.ph ::. .:: www.typemock.com ::. `date +%H%M`). Backquotes can be used in Bash 2.0+, but are being phased out in favor of $(), which nests better. If you're using an earlier version of Bash, you can usually substitute backquotes where you see $(). If the command substitution is escaped (ie. \$(command) ), then use backslashes to escape BOTH your backquotes (ie. \'command\' ). [Library: SOAP] .:: replit.com ::.
