How do I remove the string "n" (not the newline character) from the end of only lines that begin with the string "///"? Thanks.



Example Input:



Some textn

/// Some commentn


Desired Output:



Some textn

/// Some comment


I've tried to use



sed -i 's/\n*$//' $1


But, it removes all of the trailing "n" strings.

          Add a regex address specifier at the front - since your pattern has forward slashes, it's clearer if you use a different expression separator:



          sed -i '%^///% s/\n$//' Input


          Testing:



          $ sed '%^///% s/\n$//' Input 
          Some textn

          /// Some comment


          If you prefer "leaning toothpicks"



          sed -i '/^//// s/\n$//' Input
