Hi All,

I have googled and spent few hours to understand about AWK usage... But still not very much clear....

Upto my understanding 'AWK' deals with files... It reads the file takes it as a input process it and gives output or writes the output to an another file...

>> Please correct me if I am wrong OR make me more clear and precise

When I tried executing below command in the command prompt

awk' '{print$1}' SNA_DB_UPG.list

awk' '{print$1}' SNA_DB_UPG.list >> test

we need to give space between the print and $1

 
print $1

But still .. after giving space also .. It is not working for me..

just noticed..

please remove the highlighted single quote

 
awk' '{print $1}' SNA_DB_UPG.list

Now it worked!! Thank you very much...

But can you please elaborate me with the logic as well.. As i am trying to understand the 'AWK'... what is all about - I know it is huge topic but the basic understanding so that I can read it further in google

Thanks again itkamaraj.. I really feel good after executing my first command using 'awk'

you can learn more in this page ( very good for awk and sed commands )

Welcome to The UNIX Grymoire!

When I executed the below code in command prompt again the same problem.... Seeking for a delimiter and not taking the below as a executable code

BEGIN { print "SNA_DB_UPG.list"," }
{ print $8, "\t", $3}
END { print " - DONE -" }
