Book or paper on awk or sed

mike_phi

Hi there all I am looking for some material on awk or gawk, if you wondering what I am talking about I mean awk as in the shell command.

e.g. ls | awk {print ($1,$2)}

I have read bits and peices of many shell scripting books and they always touch on awk but not in great depth the frusterating bit is most of the books

mention thet awk is almost a fully developed programming language but one never gets to see what it can do besides how it as able to select collumnst etc.

so I thought I would like to get my hands on a detailed paper I could download or a book I could buy.

another comand that has been mentioned to have allot more to it than most literature dares to describe is the "sed" command

e.g.

sed /"1"/"one"/

here the same as awk if anyone knows of any literature describing this "languae" please do send it on

for those of you who dont know what I am talking about both "awk" and "sed" are shell comands in a unix/linux based system.

cheers

Hi there me again,

I was wondering does anybody know how one could nest sed in a awk statement, trying to avoid wrpping seperate sed snd awk scripts in a shell script would like to wrap sed in awk directly

cheers

After playing around with a few awk scripts and trying all sorts of wonderfulll things, I managed to answer my question using the best posible method, i.e by Practice.

Basically for anyone interested in finding out how this can be done from an awk srcipt just do the following.

use the awk function system("<some sommand>")

and in the some commad area you can exacute any sed command you like and any other command you would like to execute of course.

cheers
