hi,
try this:
i got the following output for your input:
not quite what I was expecting , My fault probably for not being clear enough with the requirement:

basically it's a case of "if there are any letters (with no spaces) directly to the left or right of the string I'm replacing, don't replace it" so the following must be left alone:
HELLORICHHELLO
HELLORICH
RICHHELLO
anything other than the above is fair game with the added condition that 'if you're doing a replace and the string being replaced is lower case, replace with lowercase, if uppercase, replace with uppercase

I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics?
Thanks!

While I do know some control characters need to be escaped, can normal characters also be escaped and still work the same way? Basically I do not know all control characters that have a special meaning, for example, ?, ., % have a meaning and have to be escaped... (11 Replies)
Hello!
I know that this expression gets rid of non-alphanumeric characters:
sed 's///g'
and I understand that it is replacing them with nothing - hence the '//'-, but I don't understand how it's doing it.
It seems it's finding strings that begin with alphanumeric and replacing them with... (2 Replies)
