sed -i '' does not work on linux

[Þórhallur Sverrisson]

I think the sed -i '' command only works on OSX, on linux I have to remove the '' part.

Thanks... what is the equivalent for edit files in place? I am on mac, but my gsed also shows -i.

man gsed
  -i[SUFFIX], --in-place[=SUFFIX]

              edit files in place (makes backup if SUFFIX supplied)
...

man sed
  -i extension
             Edit files in-place, saving backups with the specified extension.  If a zero-
             length extension is given, no backup will be saved.  It is not recommended to
             give a zero-length extension when in-place editing files, as you risk corrup-
             tion or partial content in situations where disk space is exhausted, etc.

It is still -i, just without the ''.

so: sed -i /tmp/test.x 's/test/junk/'
