Need help in concat of two lines in a file
Hi ,

Need help in concating two lines based on certain character, for example my file has the messages :

Code:
:57A:qweqweww
:58A:qeqewqeqe
-}$
{1:fffff2232323}{2:123123dasds}{4:
:20:121323232323232
:21:sdsadasdasddadad

if the line ends with "-}$" or if a line starts with "{1:" then it should append the next line or to the previous line , like below

Code:
:57A:qweqweww
:58A:qeqewqeqe
-}${1:fffff2232323}{2:123123dasds}{4:
:20:121323232323232
:21:sdsadasdasddadad
