Hello, mike This command is made out of 3 strings. The first one is: On Saturday, September 12, 2026, at 5:41 PM, mikethe1wheelnut wrote: > '^[^:]+:' The second one is: On Saturday, September 12, 2026, at 5:41 PM, mikethe1wheelnut wrote: > $user And the third one is: On Saturday, September 12, 2026, at 5:41 PM, mikethe1wheelnut wrote: > ':'
As you can see, these 3 strings are separated by the caret (^) symbol. This symbol is a symbol used for concatenation of strings in rc shell. Rc will automatically insert this symbol for you to concatenate strings with no spaces if you remove it - just like in Bourne shell, but here the symbol was put in explicitly either to improve readability (so you can see the 3 strings easier) or adhere more to Plan 9 semantics, most likely both ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tc4b53f9fc2b1c71a-M427d9a952cbb409ceaed23b2 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
