This cannot be done with any stream-oriented tool (sed, awk, ...). Just move the result file in place of the source file afterwards:
Surely this is false, what about:
Code:
sed -i 's/[[:blank:]]/|/g' file

Thanks, but this command replaces each space/tab with a delimiter which i dont expect. And i have removed the i option as it is not supported in my machine.

While that may be convenient, it's not doing anything in place. It creates a temp file and then clobbers the original with it. It's just a shortcut for the procedure in the post to which you are responding.

If you truly want to do it in place, you'll need to use something like ed or ex.

Thanks Alister, I was not aware of the -i implementation detail, which is interesting. Smilie

I like your passing of commands to ed to perform the edit, which seems very natural - use the editor to make edits. But I wonder why the -i implementation did not do something similar. Moreover, why all sed versions do not have this feature is strange.
