Removing blank spaces, tab spaces from file

Hello All,

I am trying to remove all tabspaces and all blankspaces from my file using sed & awk, but not getting proper code. Please help me out.

My file is like this (<b> means one blank space, <t> means one tab space)-

$ cat file
NARESH<b><b><b>KUMAR<t><t>PRADHAN
<t><t>RAJESH<b><b><b><b><t><t>MITRA

The code should give the following output-

NARESH KUMAR PRADHAN
RAJESH MITRA

Note-

1. All the tab spaces got removed and treated as single blankspace.
2. All the blank spaces were removed and treated as single blank space.

Thanks,
Naresh

-All the tab spaces got removed and treated as single blankspace.
cat file | sed "s/\t\t*/ /g"
All the blank spaces were removed and treated as single blank space.
cat file | sed "s/ */ /g"
(look in "s/ */" are 2 spaces )
all:
cat file | sed "s/ / /g"| sed "s/\t\t/ /g"

Thank you very much, yes it's working fine now. ONe thing to note here-

In AIX if we manually edit a file to include tabspaces, then these cmd may not work fine. One alternate cmd I found-

sed 's/'"$(echo '\011')"'//g;s/ //g' file

tr change all tabs => spaces.
tr -s is also nice cmd to compress every char*N.

cat file | tr "\t" " " | tr -s " " 
cat file | tr "\011" " " | tr -s " " 
cat file | tr $'\x09' " " | tr -s " "
