Hi All,

Thank you very much for your explaination.

@marcus121 : This is pretty clear now. just one point..

Quote:
awk -F, '{printf("%i,%s,%s,%i,%i\n",$1,$2,$3,$4,$5)}' filename | grep -v '0,,0,0,0,,'
It is clear that above will print only 5 fields ( exclude TESTING
i.e

Quote:
88562848,21-JAN-08,2741079, -1188,-7433,TESTING
88558314,21-JAN-08,2741189, -1273,-7976,TESTING
now grep -v '0,,0,0,0,,' , I guess pointing to -
1 st field - 0
2nd - null
3rd, 4th, 5th - 0
6 th - null ..

but in the resulting file, there will be no 6th field (TESTING) !!. then for what purpose, the last 2 commas are there in grep?


also, regarding the comma in 5th and 6th field in the new file..
my requirement is..

instead of 2,25 i want to print (2*100)+25 i.e 225
in general, 4th and 5th field, i want the below value

(value_before_comma*100)+value_after_comma

though I am working on it.. trying like $4*=100 but I am having problem in splitting both values for doing different calulation
I appreciate if i can get some clue.

Thanks.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
