Hi All... thanks for all your amazing replies Smilie

@kato - ur code is working absolutely fine Smilie

@sk1418 - i liked ur code for the output format... but when i tried to use it in my script it is giving error for "column -s" command

error diaplayed is :
./log_test4.ksh[23]: column: not found

i also tried to man column but it seems it is not supported here

pht025a2:/home/oper/pk264w/log_script> man column
No manual entry for column.

This is what i used...

awk '{print "|"$4"#|"$7"#|"$9"# |"}' mail_log_status.log | column -s"#" -t | awk 'BEGIN{line=""}{l=length($0);if(length(line)
==0)for(i=1;i<l;i++)line=line"-";print line;print $0}END{print line}'

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
