Hi All,
Please help me out with a script which checks whether a given file say abc.txt is in ASCII format and data is tab-delimited. If the condition doesn't satisfy then it should generate error code "100" for file not in ASCII format and "105" if it is not in tab-delimited format.

amplot
AMPLOT(8) System Manager's Manual AMPLOT(8)
NAME
amplot - visualize the behavior of Amanda
SYNOPSIS
amplot [ -c ] [ -e ] [ -g ] [ -l ] [ -p ] [ -t T ] amdump_files
DESCRIPTION
Amplot reads an amdump output file that Amanda generates each run (e.g. amdump.1) and translates the information into a picture format
that may be used to determine how your installation is doing and if any parameters need to be changed. Amplot also prints out amdump lines
that it either does not understand or knows to be warning or error lines and a summary of the start, end and total time for each backup
image.
Amplot is a shell script that executes an awk program (amplot.awk) to scan the amdump output file. It then executes a gnuplot program
(amplot.g) to generate the graph. The awk program is written in an enhanced version of awk, such as GNU awk (gawk version 2.15 or later)
or nawk.
During execution, amplot generates a few temporary files that gnuplot uses. These files are deleted at the end of execution.
See the amanda(8) man page for more details about Amanda.
OPTIONS
-c Compress amdump_files after plotting.
-e Extend the X (time) axis if needed.
-g Direct gnuplot output directly to the X11 display (default).
-p Direct postscript output to file YYYYMMDD.ps (opposite of -g).
-l Generate landscape oriented output.
-t T Set the right edge of the plot to be T hours.
The amdump_files may be in various compressed formats (compress, gzip, pact, compact).
INTERPRETATION
The figure is divided into a number of regions. There are titles on the top that show important statistical information about the configu-
ration and from this execution of amdump. In the figure, the X axis is time, with 0 being the moment amdump was started. The Y axis is
divided into 5 regions:
QUEUES: How many backups have not been started, how many are waiting on space in the holding disk and how many have been transferred
successfully to tape.
%BANDWIDTH: Percentage of allowed network bandwidth in use.
HOLDING DISK: The higher line depicts space allocated on the holding disk to backups in progress and completed backups waiting to be
written to tape. The lower line depicts the fraction of the holding disk containing completed backups waiting to be written to tape
including the file currently being written to tape. The scale is percentage of the holding disk.
TAPE: Tape drive usage.
%DUMPERS: Percentage of active dumpers.
The idle period at the left of the graph is time amdump is asking the machines how much data they are going to dump. This process can take
a while if hosts are down or it takes them a long time to generate estimates.

Reports lines it does not recognize, mainly error cases but some are legitimate lines the program needs to be taught about.
