With GNU awk 4 you can do this:
$ awk -v wd=2 '$wd~/[^ ]/{print $1, $wd}' FIELDWIDTHS="6 4 4 4 4 4 4" file
Name Mon
A Y
F Y
$ awk -v wd=3 '$wd~/[^ ]/{print $1, $wd}'...

info sed:
So - use the escaped \& sequence there. And, for multiple search patterns, use a group regex with the * character:
sed 's/<td> \(&nbsp; \)*/<td> \&nbsp; /g' file
<tr> some td tags...

-e is redundant here. If your SED supports extended regexps:

$ echo "&nbsp; &nbsp; &nbsp; a &nbsp; &nbsp; &nbsp;" | sed -r 's/(&nbsp; *)+/\&nbsp;/g'
&nbsp;a &nbsp;

$ The ( ) brackets group a...

Corona688 is right - use the + repetition indicator instead of the * (which indicates zero or more repetitions).

You could also try the following, which, other than copying the 1st line of your sample input file unchanged to the output, seems to create the output you said you want (and I don't understand from...

Hello thomasraj87,

As mentioned by RudiC previously, kindly put your requirements all together in a single post with proper sample Input_file and proper expected output_file.

For your current...

@OP: And please do this right from the beginning when you start the thread.

The example in post #6 should also work with the extra tr tags:
awk '{p=$0} getline<f>0{$1=$1 p}1' FS='<td>'...

paste file1 file2

$ awk 'NR==FNR{a[NR]=$0;next}{print a[FNR],$0}' file1 file2
1 text1
2 text2
3 text3
4 text4

sed 's# \{1,\}#-#g' infile

thomasraj87,

try it with tr instead:

tr -s ' ' '-' < /tmp/1.txt

-r is gnu sed only!
try

awk '{gsub(" ","-")}1' infile

Another way with "stty":

$ cat noEchoPass.sh
sttySettings=`stty -g`
echo "Password: "
stty -echo
read pass
stty "${sttySettings}"
echo "pass: [${pass}]"
$ ./noEchoPass.sh
Password:
pass:...

read -sp "password: " pass

echo $pass
