remove space between the operator, script required...

Shell Programming and Scripting

Hi...

i need a script to remove the space before and after the operator like( +, -, ||, &&).

Ex :

Input file

apple + manago

mango && fresh + apple fresh || fruit

Desired output:

apple+manago

mango&&fresh+apple fresh||fruit

Note: betwee the desired operator space should be removed, between words do not remove space.

Thanks in advance,
Vasanth

Try to build something like this...

echo "mango && fresh + apple fresh || fruit" | sed 's/\(.*\)\( && \)\(.*\)\( + \)\(.*\)\( || \)\(.*
\)/\1\&\&\3+\5||\7/'

Dear rakeshawasthi ,

i have a big file containing different names, and the operators(+,&&. -. ||) not in the a proper order. Kindly concern about the spaces near to the operators only.

And input is a file....

Thanks in advance...
