how to remove spaces in a string using sed.
Hello,

I have the following to remove spaces from beginning and end of a string.
infile=`echo "$infilename" | sed 's/^ *//;s/ *$//`

How do I modify the above code to remove spaces from beginning, end and in the middle of the string also.

ex:
Shell Programming is fun
Result should be:
ShellProgrammingisfun


ThankYou,
Radhika.

Bug Unix Book
A book that I've had success with is: UNIX Shells, by Ellie Quigley. It has some typos in it but it's rather good.
