Question Help needed in character replacement in Korn Shell
How do I replace a space " " character at a particular position in a line?

e.g. I have a file below

Code:
$ cat i2
111 002 A a
33 0011 B c
2222 003 C a


I want all the 1st spaces to be replaced with forward slash "/" and the 3rd spaces to have 5 spaces to get the output below:


Code:
111/002 AAA     a
33/0011 BBB     c
2222/003 CCC     b

I created a shell which would achieve this but I'm looking for a easier way.

Code:
$ cat test.ksh
#!/bin/ksh

cut -d' ' -f1 < $1 > 1st_word
cut -d' ' -f3 < $1 > 3rd_word

while read line
do

sed -e "s/$line /$line\//g" $1 | grep $line

done < 1st_word > tmp_ouput


while read line
do

sed -e "s/$line /$line     /g" tmp_ouput1 | grep $line

done < 3rd_word


Any help will be appreciated

Steve

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
