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
Code:
awk' '{print$1}' SNA_DB_UPG.list
It does not take this as a command and further seeking for a terminator...
Further I felt better to give some file to print the output as below:
Code:
awk' '{print$1}' SNA_DB_UPG.list >> test
But Alas no luck..
Please share few more examples... I gone through with older posts as well.. But nothing clicked me..
