Check out tr(1).
There are other ways, but for basic stuff, it is easy and fast.
I use it often for stripping out the extra CRs from MSDOS files.
Something like:
tr -d "\r" < dirtydos > cleanunix
does the trick.
But it will do replaces and pretty much anything. Its syntax is
a little different that regular expressions type (maybe a little
easier actually) so read the man page.
