Hi,
I have a quick question on parsing the hour/minute and value from a text file and remove the seconds portion. For example in the below text file:
20:26:01 95.83

What is the correct syntax to have the awk parse the next line as well? The next in bold is where I think it should go, but I wanted to ask the experts since I am a beginner. The file to be parsed is attached as well. Thank you :).

prev
PREV(1) [nmh-1.5] PREV(1)NAME
prev - show the previous message
SYNOPSIS
prev [+folder] [-showproc program] [-showmimeproc program] [-header | -noheader] [-checkmime | -nocheckmime] [switches for showproc or
showmimeproc] [-version] [-help]
DESCRIPTION
Prev performs a show on the previous message in the specified (or current) folder. Like show, it passes any switches on to the program
named by showproc or showmimeproc, which is called to list the message. This command is almost exactly equivalent to "show prev". Consult
the manual entry for show(1) for all the details.
FILES
$HOME/.mh_profile The user profile
PROFILE COMPONENTS
Path: To determine the user's nmh directory
Current-Folder: To find the default current folder
showproc: Program to show non-MIME messages
showmimeproc: Program to show MIME messages
SEE ALSO show(1), next(1)DEFAULTS
`+folder' defaults to the current folder
`-checkmime'
`-header'
CONTEXT
If a folder is specified, it will become the current folder. The message that is shown (i.e., the previous message in sequence) will
become the current message.
BUGS
prev is really a link to the show program. As a result, if you make a link to prev and that link is not called prev, your link will act
like show instead. To circumvent this, add a profile-entry for the link to your nmh profile and add the argument prev to the entry.
