Full Discussion: variables use upper case? sed : output to the same file?

A1 : not necessarily, you can also use small letters in the variables.

A2 : it is not possible to use the file of input as file of output.
Unhappyly you will have that to generate a separate file for output and if to desire, rename it with the name of the file of
input.

e.g.: sed -e s/here/there/g input.file > output.file;mv output.file input.file

I hope help you
