hp ux version of sed command

[Hemang75]

wanted a similar sed command for hp ux
sed '/Pattern/,+4 d' - works fine in Linux.

[Steven E. Protter]

Shalom,

Did you try it in HP-UX?

Does it actually work differently than in Linux?

sed is kind of sed. I can't remember it acting differently in HP-UX and Linux. I'm not a heavy user but have exchanged sed scripts between the two without a second thought.

yes, I tried using with Linux and it works but not with HP-UX

Fun with regular expressions.

I thought that it worked on HP-UX, but that it was supposed to be dot relative (.+4). Could not get it to work...

Scratching my head I hopped into vi and used the colon escape ":g/Pattern/,.+4 d" and it worked just fine. Everybody is gone for the holiday, perhaps an answer will show up next week.

Hi:

Well the GNU versions of many utilities are far more feature-rich than the HP-UX ones, so this doesn't surprise me in the least.

In fact, the GNU documentaion notes that the form:

addr1,+N

...is a GNU extension that matches addr1 and the N lines following addr1.

We can emulate your 'sed' command by using a bit of Perl which in this case is easy enough to deduce:

# perl -ne 'm/Pattern/ and $i=1,next;next if $i && $j++<4;print' file

Hi (again):

If you like, you can fetch a GNU 'sed' from the Porting Centre. Be sure to get the run-time dependencies for a binary; or the build-time dependencies if you are compiling your own.
