Code:
#  :<<COMMENTBLOCK
# if [ "$month -eq 3 ] || [ "$month -eq 6 ]
# then
# echo "inc = 1"
# else
# echo "inc = 2"
# fi
# COMMENTBLOCK


In case you are trying to use a HERE document, as suggested you need to get rid of the colon : in front of the sign <<, and no space at the final COMMENTBLOCK :



So if you need those lines commented out you need to use the first code.

If you are trying to achieve something else with your script, then you need to look in your script and change it accordingly, or post here what are you trying to achieve.
Hi Rubin,

Thanks for your explanation. I will write exactly what I need

Like in C or in C++, we have multiple lines of comments start like

/*
bla bla bla
*/

Likewise, I need the same kind of comments in Shell scripts. Is it possible here ?

1 #! /usr/bin/ksh
2 month=`date +"%m"`
3 echo $month
4
5 <<COMMENTBLOCk
6 if [ "$month" -eq 3] || [ "$month" -eq 6]
7 then
8 echo "inc = 1"
9 else
10 echo " inc = 2"
11 fi
12 COMMENTBLOCK
13
14 case $month in
15 3|6|9|12) echo "Yes";;
16 *) echo "No";;
17 esac
18
19 echo "This is the last line"

Query : I need to block the line number from 5 to 12 (except # option and line no from 14 to 19 should execute as usual. Can you pls give the solution for it?

Many of Unix Experts are replied for my query. Many thanks to you.

Thanks
Yamini

LEARN ABOUT LINUX

repertoiremap

REPERTOIREMAP(5)						 Linux User Manual						  REPERTOIREMAP(5)

NAME

       repertoiremap - map symbolic character names to Unicode code points

DESCRIPTION

       A  repertoire  map  defines  mappings  between  symbolic character names and Unicode code points when compiling a locale with localedef(1).
       Using a repertoire map is optional, it is needed only when symbolic names are used instead of now preferred Unicode code points.

   Syntax
       The repertoiremap file starts with a header that may consist of the following keywords:

       <comment_char>
	      is followed by a character that will be used as the comment character for the rest of the file.  It defaults to the number sign (#).

       <escape_char>
	      is followed by a character that should be used as the escape character for the rest of the file to mark characters  that	should	be
	      interpreted in a special way.  It defaults to the backslash ().

       The mapping section starts with the keyword CHARIDS in the first column.

       The mapping lines have the following form:

       <symbolic-name> <code-point> <comment>
	      This defines exactly one mapping, <comment> being optional.

       The mapping section ends with the string END CHARIDS.

FILES

       /usr/share/i18n/repertoiremaps
	      Usual default repertoire map path.

CONFORMING TO

       POSIX.2.

NOTES

       Repertoire maps are deprecated in favor of Unicode code points.
