copy a line from one file to another
I like to know what unix command i can use to append the second line of file #1 to the end of file #2 so that it performs the following. Thanks in advance. The purpose of this is to keep track of another log file (from crontab) that i have which the log content is flushed every 5 minutes so that i need to keep copying the content when it is ready before it is flushed. Thanks.
###BEFORE###
<file #1>
this is file #1, line 1
this is file #1, line 2
<file #2>
this is file #2
###AFTER###
<file #1>
this is file #1, line 1
this is file #1, line 2
<file #2>
this is file #2
this is file #1, line 2

cuebreakpoints
cuebreakpoints(1) General Commands Manual cuebreakpoints(1)
NAME
cuebreakpoints - report track breakpoints from a CUE or TOC file
SYNOPSIS
cuebreakpoints [ { -i format | --input-format=format } { --append-gaps | --prepend-gaps | --split-gaps } ] [ file ... ]
cuebreakpoints --help
DESCRIPTION
cuebreakpoints reports the track breakpoints found in CUE and TOC files, which are typically created by compact disc ripping software. The
breakpoints are in a format usable by shnsplit (part of the shntool package).
Three approaches to track pregaps are availabe: append (to previous track), prepend (to succeeding track), and split (from both preceding
and succeeding tracks). The split approach can result in up to twice as many breakpoints being reported as there are tracks on the disc.
The first track's pregap cannot be appended to the previous track, so it is prefixed to the track in both append and prepend modes. If you
want the track without it, use the --split-gaps option.
If no filenames are specified, cuebreakpoints reads from standard input, and an input format option must be specified. If one or more
filenames is provided, but the input format option is not specified, the input format will be guessed based on each file's suffix (e.g.,
.cue or .toc). This heuristic is case-insensitive.
OPTIONS
-h, --help
displays a usage message and exits.
-i format, --input-format=format
sets the expected format of the input file(s) to format, which must be either cue or toc.
--append-gaps
appends pregaps to the end of the previous track. This is the default.
--prepend-gaps
prefixes pregaps to the beginning of each subsequent track.
--split-gaps
separates pregaps from both the preceding and succeeding tracks.
If more than one of --append-gaps, --prepend-gaps, and --split-gaps are specified, all except the last encountered are ignored.
EXIT STATUS
cuebreakpoints exits with status zero if it successfully generates a report for each input file, and nonzero if there were problems.
