this is to reverse a file.
Quote:
a[NR]=$0
NR (Record number) is a number associated with each record.
$0 stands for entire line (one line in the input file)
so a[NR]=$0 means it will store each line in array 'a'.

Hope you got it (am not a good teacher Smilie )

BYZANZ-RECORD(1)					      General Commands Manual						  BYZANZ-RECORD(1)

NAME
byzanz-record - record your desktop session to an animated GIF SYNOPSIS
byzanz-record [options] FILENAME DESCRIPTION
Byzanz records your desktop session to an animated GIF. You can record your entire screen, a single window, or an arbitrary region. byzanz-record allows you to make recordings from the command line. Graphical users may want to use the panel applet instead. OPTIONS
Application Options: -d, --duration=SECS Duration of animation (default: 10 seconds) --delay=SECS Delay before start (default: 1 second) -c, --cursor Record mouse cursor -a, --audio Record audio from the default input device. This only works if the output format supports it and will otherwise cause an error. -x, --x=PIXEL X coordinate of rectangle to record -y, --y=PIXEL Y coordinate of rectangle to record -w, --width=PIXEL Width of recording rectangle -h, --height=PIXEL Height of recording rectangle -v, --verbose Be verbose --display=DISPLAY X display to use Help Options: -?, --help Show help options --help-gtk Show GTK+ Options --help-all Show all help options OUTPUT FILE
After byzanz-record is finished, the recording is written to FILENAME. The format is determined by the filename extension. The following formats are supported: gif Record to an animated GIF image. Use this if you want to record a mostly static screen with a limited amount of colors, such as using a file manager or an office application. This is the default and will be used if an unrecognized extension is used. ogg, ogv Record to an Ogg Theora video. This format supports audio. Use this if you want to record dynamic contents, such as video playback. flv Record to a Flash Screen video. This recording method is lossless. Use it if you want to postprocess the file in other applications. byzanz Record to Byzanz' internal debugging format. This is useful for benchmarking Byzanz or if you want to convert the recording to mul- tiple formats later. You can use byzanz-playback(1) to convert the file. SEE ALSO
