Hello All

Kindly tell me.. sed and awk command requires macros for advanced processing. If it is there, how to use that.

Kindly help me.

Thanks

Hi,

Maybe I misunderstand, but I've never used macro's (didn't know they excisted) in all the years I use sed/awk.

Can you be a bit more elaborate about what it is you heard/read.

please follow sed & awk command book -- oreilly ( page 73 )

example is to create the index page. for that they use macros like

Chapter title (.Se)
Section heading (.Ah)
Subsection heading (.Bh)

sed command is like
sed -n '
s/^\.Se /CHAPTER /p
s/^\.Ah / A. /p
s/^\.Bh / B. /p' $*

Thanks

Hi again,

Thanks for the sepcification, makes life easier

The reference to macro's have nothing to do with grep/sed (as stated on page 70, bottom paragraph). The macro file they are talking about (/usr/lib/macros/mmt) comes with troff (page 71, top) and is used in the getmac script.

These (troff) macro files migth not be installed on your box.

Hope this clears things up a bit.
