Hi,

One more thing. I also wanted to display the column headers for the badrec file as well.
I'm witting the above code in a bash script. Once i write the good and bad to the goodrec and badrec files and finally i'm moving the goodrecs and badrec on Hadoop HDFS. Once the process is complete it should show the sucess message, count of goodrecs and badrec records on the console. Also it should display the HDFS path where i'm storing the file. How this can be done.How the print statement written in the script file will display the result on the console
Below is my script file :
Code:
#!/bin/bash
awk -F "," 'NR == FNR {h = (h == "") ? $1 : (h FS $1); gsub("[)(]", "-", $2); split($2, a, "-"); d[NR] = a[1]; l[NR] = a[2]; n[NR] = ($3 == "NOT NULL") ? 1 : 0; next}
  FNR == 1 {print h > "goodrec"}
 {for(i = 1; i <= NF; i++)
  {if(((d[i] == "Numeric" && (($i + 0) == $i || $i == "")) || d[i] == "String") && (length($i) <= l[i]) && (length($i) >= n[i]))
      {f = 1} else {f = 0};
    if(f == 0) {print $0 > "badrec"; next}} print $0 > "goodrec"}' df.txt df.txt
hadoop fs -put /home/hduser/validate/badrec /user/hduser/Dataparse/
hadoop fs -put /home/hduser/validate/goodrec /user/hduser/Dataparse/

If i excecute the ablove code the goodrec and badrec are dumped on HDFS in the below path
Quote:
/user/hduser/Dataparse/
And on the console i would like to get :
Quote:
Parsing is Success
Count of Goodrec : 3
Count of badrec : 4
Validated records are found on the path "/user/hduser/Dataparse"
Please help me how this can be done ?

gst-complete-0.8

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
