How to tell GNU sed or common sed(simple but I need it)

[adaaje]

Hi guys,

I tried to running some sed command in my linux something like [sed '/|$/!N;s/\n//'], but it doesn't work same as my unix sed.

I assume my linux has different sed format, I typed in my linux : "man sed"

and it said :

NAME
       sed - manual page for sed version 4.1.3
...

GNU sed also supports some special 2-address forms:
...

So, the question is how many sed format do we have and how to tell the difference ? and what sed command shoud I use to have the same result as in unix sed [sed '/|$/!N;s/\n//'] ?

Thx guys,

What Unix do you mean by "unix"? It seems to work okay on Solaris.

Yes, It works fine using "Unix solaris sed" but not with my "linux mandriva sed". So, I was just wondering what sed that I have in my linux, THX.

On Linux you will have GNU sed. sed --version will confirm it.

And as Richard Stallman said himself:
GNU is Not Unix.
