Replace trailing whitespaces with pipe symbol using perl

I want to replace the whitespace with Pipe symbol to do a multiple pattern matching for the whole text "mysqld failed start" and same as for other text messages Below are the messages stored in a file seperate by whitespace

Code:
mysqld failed start 
nfsd mount failed 
rpcbind failed to start

for each text i need to add the pipe symbol so that it will be easier to do mutliple search pattern similar to egrep.

expected o/p

Code:
mysqld failed start|nfsd mount failed|rpcbind failed to start

NAME
funnel - split one pipe stream to one or more files or programs SYNOPSIS
funnel [|] [>[>]file] [|process] DESCRIPTION
The funnel program will read data from standard input and write it to several output streams. The | symbol means to copy standard input to standard output. The > symbol means that a file name immediately follows with no separating spaces, the file will be truncated if it exists or created if it doesn't. The >> means that the file is to be appended to if it exists. A | symbol followed immediately by text indicates a command that is to be run by system() and will have all input piped to it. EXIT STATUS
0 No errors 1 Error opening input Other errors are 100 + number of commands or files that fail AUTHOR
This program, its manual page, and the Debian package were written by Russell Coker <russell@coker.com.au>. FEATURES
Uses popen (3) for output so that shell expansion gets performed. If you want such shell expansion then you must ensure that you quote the parameters correctly so that they get expanded by popen (3) not the shell that calls funnel. SEE ALSO
