grep, awk, typeset in a shell script..
For e.g I have a file named "relation" which has three coloums i.e

JOHN MARY JACK
PETE ALISIA JONNY
TONY JACKIE VICTOR

If I do
grep -w 'JOHN' relation | awk '{print""$1" is husband of "$2" & father of "$3""}'

It gives out
JOHN i husband of MARY & father of JACK (which is desired output for me)

I put this thing into script but it stops working. All I am doing is to change the input in Upper case & using grep, awk after that.

#!/usr/bin/ksh
name=$1
print "$name"
echo "$name" | tr '[a-z]' '[A-Z]' >$NAME
print "$NAME"
grep -w "$NAME" relation |awk '{print""$1" is husband of "$2" & father of "$3""}' >$out
print "$out"
exit 0

If I run it like ./scriptname john
it gives output
john
JOHN

Can anyone plz help me to fix it..

I had given an example.

zfgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
